   frequency of the carrier is not fixed but changes at fixed intervals under
   the direction of a coded sequence. The wide RF bandwidth needed by such a
   system is not required by spreading of the RF energy about the carrier but
   rather  to  accommodate  the range of frequencies to which the carrier
   frequency can hop. The test of a frequency hopping system is that the near

§ 2.102   Assignment of frequencies.

   top

   (a)  Except  as  otherwise provided in this section, the assignment of
   frequencies and bands of frequencies to all stations and classes of stations
   and the licensing and authorizing of the use of all such frequencies between
   9  kHz  and  275  GHz,  and  the  actual  use  of such frequencies for
   radiocommunication or for any other purpose, including the transfer of
   energy  by  radio,  shall be in accordance with the Table of Frequency
   Allocations in §2.106.

   (b)  On  the condition that harmful interference will not be caused to
   services operating in accordance with the Table of Frequency Allocations the
   following exceptions to paragraph (a) of this section may be authorized:

   (1) In individual cases the Commission may, without rule making proceedings,
   authorize  on  a  temporary  basis only, the use of frequencies not in
   accordance with the Table of Frequency Allocations for projects of short
   duration  or  emergencies where the Commission finds that important or
   exceptional circumstances require such utilization. Such authorizations are
   not intended to develop a service to be operated on frequencies other than
   those allocated such service.

   (2) A station for the development of techniques or equipment to be employed
   by services set forth in column 5 of the Table of Frequency Allocations may
   be authorized the use of frequencies allocated to those services or classes
   of stations.

   (3)  Experimental stations, pursuant to part 5 of this chapter, may be
   authorized  the use of any frequency or frequency band not exclusively
   allocated to the passive services (including the radio astronomy service).

   (4) In the event a band is reallocated so as to delete its availability for
   use by a particular service, the Commission may provide for the further
   interim  use  of the band by stations in that service for a temporary,
   specific period of time.

   (c) Non-Federal stations may be authorized to use Federal frequencies in the
   bands above 25 MHz if the Commission finds, after consultations with the
   appropriate Federal agency or agencies, that such use is necessary for
   coordination of Federal and non-Federal activities: Provided, however, that:

   (1) Non-Federal operation on Federal frequencies shall conform with the
   conditions agreed upon by the Commission and NTIA (the more important of
   which  are  contained in paragraphs (c)(2), (c)(3), and (c)(4) of this
   section);

   (2) Such operations shall be in accordance with NTIA rules governing the
   service to which the frequencies involved are allocated;

   (3) Such operations shall not cause harmful interference to Federal stations
   and, should harmful interference result, that the interfering non-Federal
   operation shall immediately terminate; and

   (4) Non-Federal operation has been certified as necessary by the Federal
   agency involved and this certification has been furnished, in writing, to
   the non-Federal licensee with which communication is required.

   (d) Aircraft stations may communicate with stations of the maritime mobile
   service. They shall then conform to those provisions of the international
   Radio Regulations which relate to the maritime mobile service. For this
   purpose  aircraft stations should use the frequencies allocated to the
   maritime mobile service. However, having regard to interference which may be
   caused by aircraft stations at high altitudes, maritime mobile frequencies
   in the bands above 30 MHz shall not be used by aircraft stations in any
   specific area without the prior agreement of all administrations of the area
   in  which interference is likely to be caused. In particular, aircraft
   stations operating in Region 1 should not use frequencies in the bands above
   30 MHz allocated to the maritime mobile service by virtue of any agreement
   between administrations in that Region.

   (e) Non-Federal services operating on frequencies in the band 25–50 MHz must
   recognize that it is shared with various services of other countries; that
   harmful interference may be caused by skywave signals received from distant
   stations of all services of the United States and other countries radiating
   power on frequencies in this band; and that no protection from such harmful
   interference generally can be expected. Persons desiring to avoid such
   harmful interference should consider operation on available frequencies
   higher  in  the  radio  spectrum not generally subject to this type of
   difficulty.

   (f) The stations of a service shall use frequencies so separated from the
   limits  of  a  band  allocated to that service as not to cause harmful
   interference to allocated services in immediately adjoining frequency bands.

   (g) In the bands above 25 MHz which are allocated to the non-Federal land
   mobile  service,  fixed  stations  may  be authorized on the following
   conditions:

   (1) That such stations are authorized in the service shown in Column 5 of
   the Table of Frequency Allocations in the band in question;

   (2) That harmful interference will not be caused to services operating in
   accordance with the Table of Frequency Allocations.

   (h) Special provisions regarding the use of spectrum allocated to the fixed
   and land mobile services below 25 MHz by non-Federal stations.

   (1)  Only in the following circumstances will authority be extended to
   stations in the fixed service to operate on frequencies below 25 MHz.

   (i) With respect to aeronautical fixed stations, only when a showing can be
   made that more suitable facilities are not available.

   (ii) With respect to fixed stations, except aeronautical fixed stations,
   only to:

   (A) Provide communication circuits in emergency and/or disaster situations,
   where safety of life and property are concerned;

   (B) Provide standby and/or backup facilities to satellite and cable circuits
   used for international public correspondence;

   (C)  Provide  standby and/or backup communications circuits to regular
   domestic communication circuits which have been disrupted by disasters
   and/or emergencies;

   (D) Provide communication circuits wholly within the State of Alaska and the
   United States insular areas in the Pacific; and

   (E) Provide communication circuits to support operations which are highly
   important   to   the  national  interest  and  where  other  means  of
   telecommunication are unavailable.

   (2)  Only in the following circumstances will authority be extended to
   stations in the land mobile service to operate below 25 MHz.

   (i) Provide communication circuits in emergency and/or disaster situations,
   where safety of life and property are concerned;

   (ii)  Provide standby and/or backup communications circuits to regular
   domestic communication circuits which have been disrupted by disasters
   and/or emergencies;

   (iii) Provide communication circuits wholly within the State of Alaska and
   the United States insular areas in the Pacific; and

   (iv) Provide communication circuits to support operations which are highly
   important   to   the  national  interest  and  where  other  means  of
   telecommunication are unavailable.

   (3) Except in the State of Alaska and the United States Pacific insular
   areas, the Commission does not intend to seek international protection for
   assignments made pursuant to paragraphs (h) (1)(ii) and (2) of this section;
   this results in the following constraints upon the circuits/assignments.

   (i) The Commission will not accept responsibility for protection of the
   circuits from harmful interference caused by foreign operations.

   (ii) In the event that a complaint of harmful interference resulting from
   operation of these circuits is received from a foreign source, the offending
   circuit(s) must cease operation on the particular frequency concerned.

   (iii) In order to accommodate the situations described in paragraphs (h)(3)
   (i) and (ii) of this section, equipments shall be capable of transmitting
   and receiving on any frequency in the bands assigned to the particular
   operation and capable of immediate change among the frequencies.

   (a) Federal stations may be authorized to use non-Federal frequencies in the
   bands above 25 MHz (except the 764–776 MHz and 794–806 MHz public safety
   bands) if the Commission finds that such use is necessary for coordination
   of Federal and non-Federal activities: Provided, however, that:

   (1) Federal operation on non-Federal frequencies shall conform with the
   conditions agreed upon by the Commission and NTIA (the more important of
   which  are  contained  in paragraphs (a)(2), (a)(3) and (a)(4) of this
   section);

   (2) Such operations shall be in accordance with Commission rules governing
   the service to which the frequencies involved are allocated;

   (3) Such operations shall not cause harmful interference to non-Federal
   stations and, should harmful interference result, that the interfering
   Federal operation shall immediately terminate; and

   (4) Federal operation has been certified as necessary by the non-Federal
   licensees involved and this certification has been furnished, in writing, to
   the Federal agency with which communication is required.

   (b) Federal stations may be authorized to use channels in the 764–776 MHz,
   794–806 MHz and 4940–4990 MHz public safety bands with non-Federal entities
   if the Commission finds such use necessary; where:

   (1)   The  stations  are  used  for  interoperability  or  part  of  a
   Federal/non-Federal shared or joint-use system;

   (2) The Federal entity obtains the approval of the non-Federal (State/local
   government) licensee(s) or applicant(s) involved;

   (3) Federal operation is in accordance with the Commission's Rules governing
   operation of this band and conforms with any conditions agreed upon by the
   Commission and NTIA; and

   (4) Interoperability, shared or joint-use systems are the subject of a
   mutual agreement between the Federal and non-Federal entities. This section
   does not preclude other arrangements or agreements as permitted under part
   90 of the rules. See 47 CFR 90.179 and 90.421 of this chapter.

§ 2.104   International Table of Frequency Allocations.

   top

   (a) The International Table of Frequency Allocations is subdivided into the
   Region  1  Table (column 1 of §2.106), the Region 2 Table (column 2 of
   §2.106), and the Region 3 Table (column 3 of §2.106). The International
   Table is included for informational purposes only.

   (b)  Regions.  For  the  allocation  of  frequencies the International
   Telecommunication Union (ITU) has divided the world into three Regions^1 as
   shown in Figure 1 of this section and described as follows:

   ^1 It should be noted that where the words “regions” or “regional” are
   without a capital “R,” they do not relate to the three Regions here defined
   for purposes of frequency allocation.

   (1) Region 1. Region 1 includes the area limited on the east by line A
   (lines A, B and C are defined below) and on the west by line B, excluding
   any of the territory of the Islamic Republic of Iran which lies between
   these  limits. It also includes the whole of the territory of Armenia,
   Azerbaijan,  the  Russian  Federation,  Georgia, Kazakhstan, Mongolia,
   Uzbekistan, Kyrgyzstan, Tajikistan, Turkmenistan, Turkey and Ukraine and the
   area to the north of the Russian Federation which lies between lines A and
   C.

   (2) Region 2. Region 2 includes the area limited on the east by line B and
   on the west by line C.

   (3) Region 3. Region 3 includes the area limited on the east by line C and
   on the west by line A, except any of the territory of Armenia, Azerbaijan,
   the  Russian  Federation,  Georgia,  Kazakhstan, Mongolia, Uzbekistan,
   Kyrgyzstan, Tajikistan, Turkmenistan, Turkey and Ukraine and the area to the
   north of the Russian Federation. It also includes that part of the territory
   of the Islamic Republic of Iran lying outside of those limits.

   (4) The lines A, B and C are defined as follows:

   (i) Line A. Line A extends from the North Pole along meridian 40° East of
   Greenwich  to  parallel  40°  North; thence by great circle arc to the
   intersection of meridian 60° East and the Tropic of Cancer; thence along the
   meridian 60° East to the South Pole.

   (ii) Line B. Line B extends from the North Pole along meridian 10° West of
   Greenwich to its intersection with parallel 72° North; thence by great
   circle arc to the intersection of meridian 50° West and parallel 40° North;
   thence by great circle arc to the intersection of meridian 20° West and
   parallel 10° South; thence along meridian 20° West to the South Pole.

   (iii) Line C. Line C extends from the North Pole by great circle arc to the
   intersection of parallel 65°30' North with the international boundary in
   Bering Strait; thence by great circle arc to the intersection of meridian
   165° East of Greenwich and parallel 50° North; thence by great circle arc to
   the intersection of meridian 170° West and parallel 10° North; thence along
   parallel 10° North to its intersection with meridian 120° West; thence along
   meridian 120° West to the South Pole.

   (c) Areas. To further assist in the international allocation of the radio
   spectrum, the ITU has established five special geographical areas and they
   are defined as follows:

   (1) The term “African Broadcasting Area” means:

   (i)  African  countries, parts of countries, territories and groups of
   territories situated between the parallels 40° South and 30° North;

   (ii) Islands in the Indian Ocean west of meridian 60° East of Greenwich,
   situated between the parallel 40° South and the great circle arc joining the
   points 45° East, 11°30' North and 60° East, 15° North; and

   (iii) Islands in the Atlantic Ocean east of line B, situated between the
   parallels 40° South and 30° North.

   (2) The “European Broadcasting Area” is bounded on the west by the western
   boundary of Region 1, on the east by the meridian 40° East of Greenwich and
   on the south by the parallel 30° North so as to include the northern part of
   Saudi Arabia and that part of those countries bordering the Mediterranean
   within  these  limits.  In addition, Iraq, Jordan and that part of the
   territory of the Syrian Arab Republic, Turkey and Ukraine lying outside the
   above limits are included in the European Broadcasting Area.

   (3) The “European Maritime Area” is bounded to the north by a line extending
   along parallel 72° North from its intersection with meridian 55° East of
   Greenwich to its intersection with meridian 5° West, then along meridian 5°
   West to its intersection with parallel 67° North, thence along parallel 67°
   North to its intersection with meridian 32° West; to the west by a line
   extending along meridian 32° West to its intersection with parallel 30°
   North; to the south by a line extending along parallel 30° North to its
   intersection with meridian 43° East; to the east by a line extending along
   meridian 43° East to its intersection with parallel 60° North, thence along
   parallel 60° North to its intersection with meridian 55° East and thence
   along meridian 55° East to its intersection with parallel 72° North.

   (4) The “Tropical Zone” (see Figure 1 of this section) is defined as:

   (i) The whole of that area in Region 2 between the Tropics of Cancer and
   Capricorn.

   (ii)  The  whole of that area in Regions 1 and 3 contained between the
   parallels 30° North and 35° South with the addition of:

   (A)  The area contained between the meridians 40° East and 80° East of
   Greenwich and the parallels 30° North and 40° North; and

   (B) That part of Libyan Arab Jamahiriya north of parallel 30° North.

   (iii) In Region 2, the Tropical Zone may be extended to parallel 33° North,
   subject to special agreements between the countries concerned in that Region
   (see Article 6 of the ITU Radio Regulations ).

   (5) A sub-Region is an area consisting of two or more countries in the same
   Region.

   (d)  Categories of services and allocations. (1) Primary and secondary
   services. Where, in a box of the International Table in §2.106, a band is
   indicated as allocated to more than one service, either on a worldwide or
   Regional basis, such services are listed in the following order:

   (i) Services the names of which are printed in “capitals” (example: FIXED);
   these are called “primary” services; and

   (ii)  Services  the  names of which are printed in “normal characters”
   (example: Mobile); these are called “secondary” services (see paragraph
   (d)(3) of this section).

   (2) Additional remarks shall be printed in normal characters (example:
   MOBILE except aeronautical mobile).

   (3) Stations of a secondary service:

   (i) Shall not cause harmful interference to stations of primary services to
   which  frequencies are already assigned or to which frequencies may be
   assigned at a later date;

   (ii) Cannot claim protection from harmful interference from stations of a
   primary service to which frequencies are already assigned or may be assigned
   at a later date; and

   (iii) Can claim protection, however, from harmful interference from stations
   of  the same or other secondary service(s) to which frequencies may be
   assigned at a later date.

   (4) Where a band is indicated in a footnote of the International Table as
   allocated to a service “on a secondary basis” in an area smaller than a
   Region,  or  in a particular country, this is a secondary service (see
   paragraph (d)(3) of this section).

   (5) Where a band is indicated in a footnote of the International Table as
   allocated to a service “on a primary basis”, in an area smaller than a
   Region, or in a particular country, this is a primary service only in that
   area or country.

   (e) Additional allocations. (1) Where a band is indicated in a footnote of
   the International Table as “also allocated” to a service in an area smaller
   than  a  Region,  or  in a particular country, this is an “additional”
   allocation,  i.e. an allocation which is added in this area or in this
   country to the service or services which are indicated in the International
   Table.

   (2) If the footnote does not include any restriction on the service or
   services  concerned  apart  from  the restriction to operate only in a
   particular area or country, stations of this service or these services shall
   have equality of right to operate with stations of the other primary service
   or services indicated in the International Table.

   (3) If restrictions are imposed on an additional allocation in addition to
   the restriction to operate only in a particular area or country, this is
   indicated in the footnote of the International Table.

   (f) Alternative allocations. (1) Where a band is indicated in a footnote of
   the International Table as “allocated” to one or more services in an area
   smaller  than  a  Region,  or  in  a  particular  country,  this is an
   “alternative” allocation, i.e. an allocation which replaces, in this area or
   in this country, the allocation indicated in the Table.

   (2) If the footnote does not include any restriction on stations of the
   service or services concerned, apart from the restriction to operate only in
   a particular area or country, these stations of such a service or services
   shall have an equality of right to operate with stations of the primary
   service or services, indicated in the International Table, to which the band
   is allocated in other areas or countries.

   (3)  If  restrictions are imposed on stations of a service to which an
   alternative allocation is made, in addition to the restriction to operate
   only in a particular country or area, this is indicated in the footnote.

   (g) Miscellaneous provisions. (1) Where it is indicated in the International
   Table that a service or stations in a service may operate in a specific
   frequency  band subject to not causing harmful interference to another
   service or to another station in the same service, this means also that the
   service which is subject to not causing harmful interference cannot claim
   protection from harmful interference caused by the other service or other
   station in the same service.

   (2) Where it is indicated in the International Table that a service or
   stations in a service may operate in a specific frequency band subject to
   not claiming protection from another service or from another station in the
   same service, this means also that the service which is subject to not
   claiming  protection shall not cause harmful interference to the other
   service or other station in the same service.

   (3) Except if otherwise specified in a footnote, the term “fixed service”,
   where appearing in the International Table, does not include systems using
   ionospheric scatter propagation.

   (h) Description of the International Table of Frequency Allocations. (1) The
   heading of the International Table includes three columns, each of which
   corresponds to one of the Regions (see paragraph (b) of this section). Where
   an allocation occupies the whole of the width of the Table or only one or
   two of the three columns, this is a worldwide allocation or a Regional
   allocation, respectively.

   (2) The frequency band referred to in each allocation is indicated in the
   left-hand top corner of the part of the Table concerned.

   (3) Within each of the categories specified in paragraph (d)(1) of this
   section, services are listed in alphabetical order according to the French
   language. The order of listing does not indicate relative priority within
   each category.

   (4) In the case where there is a parenthetical addition to an allocation in
   the International Table, that service allocation is restricted to the type
   of operation so indicated.

   (5) The footnote references which appear in the International Table below
   the allocated service or services apply to more than one of the allocated
   services, or to the whole of the allocation concerned.

   (6) The footnote references which appear to the right of the name of a
   service are applicable only to that particular service.

§ 2.105   United States Table of Frequency Allocations.

   top

   (a) The United States Table of Frequency Allocations (United States Table)
   is subdivided into the Federal Table of Frequency Allocations (Federal
   Table,  column  4  of  §2.106)  and the non-Federal Table of Frequency
   Allocations (non-Federal Table, column 5 of §2.106). The United States Table
   is based on the Region 2 Table because the relevant area of jurisdiction is
   located primarily in Region 2^1 ( i.e. , the 50 States, the District of
   Columbia, the Caribbean insular areas,^2 and some of the Pacific insular
   areas).^3 ^4 The Federal Table is administered by NTIA^5 and the non-Federal
   Table is administered by the Federal Communications Commission (FCC).^6

   ^1 See 2.104(b) for definitions of the ITU Regions.

   ^2 The Caribbean insular areas are Puerto Rico, the United States Virgin
   Islands, and Navassa Island.

   ^3 The Pacific insular areas located in Region 2 are Johnston Atoll and
   Midway Atoll.

   ^4 The operation of stations in the Pacific insular areas located in Region
   3 are generally governed by the Region 3 Table ( i.e. , column 3 of 2.106).
   The Pacific insular areas located in Region 3 are American Samoa, Guam, the
   Northern Mariana Islands, Baker Island, Howland Island, Jarvis Island,
   Kingman Reef, Palmyra Island, and Wake Island.

   ^5 Section 305(a) of the Communications Act of 1934, as amended. See Public
   Law 102–538, 106 Stat. 3533 (1992).

   ^6 The Communications Act of 1934, as amended.

   (b) In the United States, radio spectrum may be allocated to either Federal
   or non-Federal use exclusively, or for shared use. In the case of shared
   use, the type of service(s) permitted need not be the same [ e.g. , Federal
   FIXED,  non-Federal MOBILE]. The terms used to designate categories of
   services and allocations^7 in columns 4 and 5 of §2.106 correspond to the
   terms in the ITU Radio Regulations. 

   ^7 The radio services are defined in §2.1.

   (c) Category of services. (1) Any segment of the radio spectrum may be
   allocated to the Federal and/or non-Federal sectors either on an exclusive
   or shared basis for use by one or more radio services. In the case where an
   allocation has been made to more than one service, such services are listed
   in the following order:

   (i) Services, the names of which are printed in “capitals” [example: FIXED];
   these are called “primary” services;

   (ii)  Services,  the names of which are printed in “normal characters”
   [example: Mobile]; these are called “secondary” services.

   (2) Stations of a secondary service:

   (i) Shall not cause harmful interference to stations of primary services to
   which  frequencies are already assigned or to which frequencies may be
   assigned at a later date;

   (ii) Cannot claim protection from harmful interference from stations of a
   primary service to which frequencies are already assigned or may be assigned
   at a later date; and

   (iii) Can claim protection, however, from harmful interference from stations
   of  the same or other secondary service(s) to which frequencies may be
   assigned at a later date.

   (d) Format of the United States Table and the Rule Part Cross Reference
   Column. (1) The frequency band referred to in each allocation, column 4 for
   Federal operations and column 5 for non-Federal operations, is indicated in
   the left-hand top corner of the column. If there is no service or footnote
   indicated for a band of frequencies in column 4, then the Federal sector has
   no access to that band except as provided for by §2.103. If there is no
   service or footnote indicated for a band of frequencies in column 5, then
   the non-Federal sector has no access to that band except as provided for by
   §2.102.

   (2) When the Federal Table and the non-Federal Table are exactly the same
   for a shared band, the line between columns 4 and 5 is deleted and the
   allocations are shown once.

   (3) The Federal Table, given in column 4, is included for informational
   purposes only.

   (4) In the case where there is a parenthetical addition to an allocation in
   the United States Table [example: FIXED-SATELLITE (space-to-earth)], that
   service allocation is restricted to the type of operation so indicated.

   (5) The following symbols are used to designate footnotes in the United
   States Table:

   (i) Any footnote consisting of “5.” followed by one or more digits, e.g. ,
   5.53, denotes an international footnote. Where an international footnote is
   applicable,  without  modification,  to  both  Federal and non-Federal
   operations, the Commission places the footnote in both the Federal Table and
   the non-Federal Table (columns 4 and 5) and the international footnote is
   binding on both Federal users and non-Federal licensees. If, however, an
   international footnote pertains to a service allocated only for Federal or
   non-Federal use, the international footnote will be placed only in the
   affected Table. For example, footnote 5.142 pertains only to the amateur
   service, and thus, footnote 5.142 is shown only in the non-Federal Table.

   (ii) Any footnote consisting of the letters “US” followed by one or more
   digits,  e.g.  , US7, denotes a stipulation affecting both Federal and
   non-Federal operations. United States footnotes appear in both the Federal
   Table and the non-Federal Table.

   (iii) Any footnote consisting of the letters “NG” followed by one or more
   digits, e.g. , NG2, denotes a stipulation applicable only to non-Federal
   operations. Non-Federal footnotes appear solely in the non-Federal Table
   (column 5).

   (iv) Any footnote consisting of the letter “G” following by one or more
   digits,  e.g.  ,  G2, denotes a stipulation applicable only to Federal
   operations. Federal footnotes appear solely in the Federal Table (column 4).

   (e) Rule Part Cross References. If a frequency or frequency band has been
   allocated to a radiocommunication service in the non-Federal Table, then a
   cross reference may be added for the pertinent FCC Rule part (column 6 of
   §2.106). For example, the band 849–851 MHz is allocated to the aeronautical
   mobile service for non-Federal use, rules for the use of the 849–851 MHz
   band have been added to Part 22—Public Mobile Services (47 CFR part 22), and
   a cross reference, Public Mobile (22), has been added in column 6 of §2.106.
   The exact use that can be made of any given frequency or frequency band (
   e.g. , channelling plans, allowable emissions, etc.) is given in the FCC
   Rule  part(s)  so indicated. The FCC Rule parts in this column are not
   allocations and are provided for informational purposes only. This column
   also may contain explanatory notes for informational purposes only.

   (f) The Commission updates §2.106 shortly after a final rule that revises
   that section is released. The address for the FCC Radio Spectrum Home Page,
   which includes the FCC Online Table of Frequency Allocations and the FCC
   Allocation History File, is http://www.fcc.gov/oet/spectrum/.

   Iran (Islamic Republic of), Japan, Pakistan, Papua New Guinea and Sri Lanka,
   the allocation of the band 415–495 kHz to the aeronautical radionavigation
   service is on a primary basis. Administrations in these countries shall take
   all practical steps necessary to ensure that aeronautical radionavigation
   stations in the band 435–495 kHz do not cause interference to reception by
   coast stations of ship stations transmitting on frequencies designated for
   ship stations on a worldwide basis (see No. 52.39).

   5.78   Different category of service: in Cuba, the United States of America
   and Mexico, the allocation of the band 415–435 kHz to the aeronautical

   Region 2) by the maritime mobile service is limited to radiotelegraphy.

   5.79A  When  establishing  coast stations in the NAVTEX service on the
   frequencies 490 kHz, 518 kHz and 4209.5 kHz, administrations are strongly
   recommended to coordinate the operating characteristics in accordance with
   the  procedures  of the International Maritime Organization (IMO) (see
   Resolution 339 (Rev.WRC–97))^3 .

   5.80  In Region 2, the use of the band 435–495 kHz by the aeronautical
   radionavigation service is limited to non-directional beacons not employing
   voice transmission.

   5.82  In the maritime mobile service, the frequency 490 kHz is, from the
   date of full implementation of the GMDSS (see Resolution 331 (Rev.WRC–97))^3
   ,  to  be  used  exclusively for the transmission by coast stations of
   navigational and meteorological warnings and urgent information to ships, by
   means of narrow-band direct-printing telegraphy. The conditions for use of
   the frequency 490 kHz are prescribed in Articles 31 and 52. In using the
   band   415–495  kHz  for  the  aeronautical  radionavigation  service,
   administrations are requested to ensure that no harmful interference is
   caused to the frequency 490 kHz.

   ^3 Note by the Secretariat: This Resolution was revised by WRC–03.

   5.83  The  frequency  500 kHz is an international distress and calling
   frequency  for  Morse  radiotelegraphy. The conditions for its use are
   prescribed in Articles 31 and 52, and in Appendix 13.

   allocation to the fixed service in the band 31–31.3 GHz may also be used by
   systems using high altitude platform stations (HAPS) in the ground-to-HAPS
   direction. The use of the band 31–31.3 GHz by systems using HAPS is limited
   to the territory of the countries listed above and shall not cause harmful
   interference to, nor claim protection from, other types of fixed-service
   systems, systems in the mobile service and systems operated under No. 5.545.
   Furthermore, the development of these services shall not be constrained by
   HAPS. Systems using HAPS in the band 31–31.3 GHz shall not cause harmful
   interference to the radio astronomy service having a primary allocation in
   the band 31.331.8 GHz, taking into account the protection criterion as
   given in Recommendation ITU–R RA.769. In order to ensure the protection of
   satellite passive services, the level of unwanted power density into a HAPS
   ground station antenna in the band 31.331.8 GHz shall be limited to −106
   dB(W/MHz)  under clear-sky conditions, and may be increased up to −100
   dB(W/MHz)  under rainy conditions to take account of rain attenuation,
   provided the effective impact on the passive satellite does not exceed the
   impact  under  clear-sky conditions as given above. See Resolution 145
   (WRC–03).

   5.544  In the band 31–31.3 GHz the power flux-density limits specified in
   Article 21, Table 21–4 shall apply to the space research service.

   5.545   Different category of service: In Armenia, Azerbaijan, Georgia,
   Mongolia, Kyrgyzstan, Tajikistan and Turkmenistan, the allocation of the
   band 31–31.3 GHz to the space research service is on a primary basis (see
   No. 5.33).

   5.546   Different category of service: In Saudi Arabia, Armenia, Azerbaijan,
   Belarus,  Egypt, the United Arab Emirates, Spain, Estonia, the Russian
   Federation, Finland, Georgia, Hungary, Iran (Islamic Republic of), Israel,
   Jordan, Latvia, Lebanon, Moldova, Mongolia, Uzbekistan, Poland, the Syrian
   Arab  Republic, Kyrgyzstan, Romania, the United Kingdom, South Africa,
   Tajikistan, Turkmenistan and Turkey, the allocation of the band 31.531.8
   GHz to the fixed and mobile, except aeronautical mobile, services is on a
   primary basis (see No. 5.33).

   5.547  The bands 31.833.4 GHz, 37–40 GHz, 40.5–43.5 GHz, 51.4–52.6 GHz,
   55.78–59 GHz and 64–66 GHz are available for high-density applications in
   the  fixed  service (see Resolutions 75 (WRC–2000) and 79 (WRC–2000)).
   Administrations should take this into account when considering regulatory
   provisions in relation to these bands. Because of the potential deployment
   of high-density applications in the fixed-satellite service in the bands
   39.5–40 GHz and 40.5–42 GHz (see No. 5.516B), administrations should further
   take into account potential constraints to high-density applications in the
   fixed service, as appropriate.

   5.547A  Administrations should take practical measures to minimize the
   potential interference between stations in the fixed service and airborne
   stations in the radionavigation service in the 31.8–33.4 GHz band, taking
   into account the operational needs of the airborne radar systems.

   5.547B   Alternative allocation: in the United States, the band 31.8–32 GHz
   is  allocated  to  the radionavigation and space research (deep space)
   (space-to-Earth) services on a primary basis.

   5.547C   Alternative allocation: In the United States, the band 32–32.3 GHz
   is  allocated  to  the radionavigation and space research (deep space)
   (space-to-Earth) services on a primary basis.

   primary basis.

   5.547E   Alternative allocation: in the United States, the band 33–33.4 GHz
   is allocated to the radionavigation service on a primary basis.

   5.548  In designing systems for the inter-satellite service in the band
   32.3–33 GHz, for the radionavigation service in the band 32–33 GHz, and for
   the  space  research  service  (deep space) in the band 31.832.3 GHz,
   administrations  shall  take all necessary measures to prevent harmful
   interference between these services, bearing in mind the safety aspects of
   the radionavigation service (see Recommendation 707).

   and Turkmenistan, the allocation of the band 34.735.2 GHz to the space
   research service is on a primary basis (see No. 5.33).

   5.551F   Different category of service: in Japan, the allocation of the band
   41.5–42.5 GHz to the mobile service is on a primary basis (see No. 5.33).

   5.551H  The  equivalent power flux-density (epfd) produced in the band
   42.5–43.5 GHz by all space stations in any non-geostationary-satellite
   system  in  the  fixed-satellite  service  (space-to-Earth), or in the

   These  epfd  values  shall be evaluated using the methodology given in
   Recommendation  ITU-R S.1586 and the reference antenna pattern and the
   maximum  gain  of  an  antenna in the radio astronomy service given in
   Recommendation ITU-R RA.1631 and shall apply over the whole sky and for
   elevation  angles  higher  than the minimum operating angle Θminof the
   radiotelescope (for which a default value of 5° should be adopted in the
   absence of notified information).

   These values shall apply at any radio astronomy station that either:

   5.552  The allocation of the spectrum for the fixed-satellite service in the
   bands 42.543.5 GHz and 47.250.2 GHz for Earth-to-space transmission is
   greater than that in the band 37.539.5 GHz for space-to-Earth transmission
   in  order  to  accommodate  feeder  links  to broadcasting satellites.
   Administrations are urged to take all practicable steps to reserve the band
   47.2–49.2  GHz for feeder links for the broadcasting-satellite service

   such   transmissions   are   used   to   extend   or   supplement  the
   satellite-to-aircraft links. Transmissions in the band 1646.51660.5 MHz
   from aircraft stations in the aeronautical mobile (R) service directly to
   terrestrial aeronautical stations, or between aircraft stations, are also
   authorized when such transmissions are used to extend or supplement the
   aircraft-to-satellite links.

   US310  In the band 14.89615.121 GHz, non-Federal space stations in the
   space research service may be authorized on a secondary basis to transmit to
   Tracking and Data Relay Satellites subject to such conditions as may be
   applied on a case-by-case basis. Such transmissions shall not cause harmful
   interference to authorized Federal stations. The power flux-density produced
   by such non-Federal stations at the Earth's surface in any 1 MHz band for
   all conditions and methods of modulation shall not exceed:
   −124 dB(W/m^2)          for 0° <Θ ≤5°.
   −124 + (Θ−5)/2dB(W/m^2) for 5° <Θ ≤ 25°.
   −114 dB(W/m^2)          for 25° <Θ ≤90°.

   where Θ is the angle of arrival of the radio-frequency wave (degrees above
   the horizontal). These limits relate to the power flux-density and angles of
   arrival which would be obtained under free-space propagation conditions.

   US311  Radio astronomy observations may be made in the bands 1350–1400 MHz,
   1718.8–1722.2  MHz,  and  4950–4990 MHz on an unprotected basis at the

   and 38°00' N and between longitudes 118°00' W and 118°50' W.

   In the bands 1350–1400 MHz and 4950–4990 MHz, every practicable effort will
   be made to avoid the assignment of frequencies to stations in the fixed and
   mobile services that could interfere with radio astronomy observations
   within the geographic areas given above. In addition, every practicable
   effort will be made to avoid assignment of frequencies in these bands to
   stations in the aeronautical mobile service which operate outside of those
   geographic areas, but which may cause harmful interference to the listed
   observatories. Should such assignments result in harmful interference to
   these  observatories,  the  situation  will  be remedied to the extent
   practicable.

   US312  The frequency 173.075 MHz may also be authorized on a primary basis
   to non-Federal stations in the Public Safety Radio Pool, limited to police
   licensees, for stolen vehicle recovery systems (SVRS). As of May 27, 2005,
   new SVRS licenses shall be issued for an authorized bandwidth not to exceed
   12.5 kHz. Stations that operate as part of a stolen vehicle recovery system
   that was authorized and in operation prior to May 27, 2005 may operate with

   and 400.15–401 MHz by the mobile-satellite service is limited to non-voice,
   non-geostationary satellite systems and may include satellite links between
   land earth stations at fixed locations.

   US321  The band 535–1705 kHz is also allocated to the non-Federal mobile
   service  on  a  secondary basis for the distribution of public service
   information from Travelers' Information Stations operating in accordance
   with the provisions of 47 CFR 90.242 on 10 kilohertz spaced channels from
   540 kHz to 1700 kHz.

   US323 In the 148–149.9 MHz band, no individual mobile earth station shall
   transmit, on the same frequency being actively used by fixed and mobile
   stations and shall transmit no more than 1% of the time during any 15 minute
   period; except, individual mobile earth stations in this band that do not
   avoid frequencies actively being used by the fixed and mobile services shall
   not exceed a power density of −16 dBW/4kHz and shall transmit no more than
   0.25% of the time during any 15 minute period. Any single transmission from

   US325  In the band 148–149.9 MHz fixed and mobile stations shall not claim
   protection from land earth stations in the mobile-satellite service that
   have  been  previously  coordinated; Federal fixed and mobile stations
   exceeding 27 dBW EIRP, or an emission bandwidth greater than 38 kHz, will be
   coordinated with existing mobile-satellite service space stations.

   US327  The band 2310–2360 MHz is allocated to the broadcasting-satellite
   service (sound) and complementary terrestrial broadcasting service on a
   primary basis. Such use is limited to digital audio broadcasting and is
   subject to the provisions of Resolution 528.

   US334  In  the  band  17.820.2  GHz,  Federal  space stations in both
   geostationary  (GSO) and non-geostationary satellite orbits (NGSO) and
   associated earth stations in the fixed-satellite service (space-to-Earth)
   may be authorized on a primary basis. For a Federal geostationary satellite
   network to operate on a primary basis, the space station shall be located
   outside the arc, measured from east to west, 70 West Longitude to 120 West
   Longitude.  Coordination  between  Federal fixed-satellite systems and
   non-Federal space and terrestrial systems operating in accordance with the
   United States Table of Frequency Allocations is required.

   (a) In the sub-band 17.819.7 GHz, the power flux-density at the surface of

   band:

   (1) –115—X dB(W/m^2 ) for δ between 0° and 5°,

   (2) –115—X + ((10 + X)/20)(δ—5) dB(W/m^2 ) for δ between 5° and 25°, and

   (3) –105 dB(W/m^2 ) for δ between 25° and 90°; where X is defined as a
   function  of  the number of satellites, n, in an NGSO constellation as
   follows:

   For n ≤ 288, X = (5/119) (n—50) dB; and

   For n > 288, X = (1/69) (n + 402) dB.

   US335  The primary Federal and non-Federal allocations for the various
   segments of the 220–222 MHz band are divided as follows:

   (1)     The     220.0–220.55/221.0–221.55,    220.6–220.8/221.6–221.8,
   220.85–220.90/221.85–221.90  and 220.925221.0/221.925222.0 MHz bands
   (Channels 1–110, 121–160, 171–180 and 186–200, respectively) are available
   for exclusive non-Federal use;

   (2)  The  220.55–220.60/221.55–221.60 MHz bands (Channels 111–120) are
   available for exclusive Federal use; and

   (3) The 220.80–220.85/221.80–221.85 and 220.900220.925/221.900221.925 MHz
   bands (Channels 161–170 and 181–185, respectively) are available for shared
   Federal and non-Federal use. The exclusive non-Federal band segments are
   also available for temporary fixed geophysical telemetry operations on a
   secondary basis to the fixed and mobile services.

   US337  In the band 13.7513.80 GHz, earth stations in the fixed-satellite
   service shall be coordinated on a case-by-case basis through the frequency
   assignment subcommittee in order to minimize harmful interference to the
   Tracking and Data Relay Satellite System's forward space-to-space link
   (TDRSS forward link-to-LEO).

   US338  In the 2305–2310 MHz band, space-to-Earth operations are prohibited.
   Additionally, in the 2305–2320 MHz band, all Wireless Communications Service
   (WCS) operations within 50 kilometers of 35°20" North Latitude and 116°53"
   West  Longitude  shall be coordinated through the Frequency Assignment
   Subcommittee of the Interdepartment Radio Advisory Committee in order to

   aeronautical telemetering and associated telecommand operations for flight
   testing of manned or unmanned aircraft, missiles or major components thereof
   on a secondary basis to the Wireless Communications Service. The following
   two frequencies are shared on a co-equal basis by Federal and non-Federal
   stations  for  telemetering  and  associated telecommand operations of
   expendable and re-usable launch vehicles whether or not such operations
   involve flight testing: 2312.5 and 2352.5 MHz. Other mobile telemetering
   uses may be provided on a non-interference basis to the above uses. The
   broadcasting-satellite service (sound) during implementation should also
   take cognizance of the expendable and reusable launch vehicle frequencies
   2312.5 and 2352.5 MHz, to minimize the impact on this mobile service use to
   the extent possible.

   US340  The band 2–30 MHz is available on a non-interference basis to Federal
   and non-Federal maritime and aeronautical stations for the purposes of
   measuring the quality of reception on radio channels. See 47 CFR 87.149 for
   the list of protected frequencies and bands within this frequency range.
   Actual communications shall be limited to those frequencies specifically
   allocated to the maritime mobile and aeronautical mobile services.

   observations), all practicable steps shall be taken to protect the radio
   astronomy service from harmful interference. Emissions from spaceborne or
   airborne stations can be particularly serious sources of interference to the
   radio astronomy service (see Nos. 4.5 and 4.6 and Article 29 of the ITU
   Radio Regulations ).

   US343  Differential-Global-Positioning-System (DGPS) Stations, limited to
   ground-based transmitters, may be authorized on a primary basis in the bands

   fixed-satellite service (Earth-to-space) shall be coordinated through the
   Frequency Assignment Subcommittee (see Recommendation ITU–R S.1342). In
   order to better protect the operation of the international standard system
   (microwave landing system) in the band 5000–5091 MHz, non-Federal tracking
   and telecommand operations should be conducted in the band 5150–5250 MHz.

   US345  In the band 402–405 MHz, the mobile, except mobile aeronautical,
   service  is allocated on a secondary basis and is limited to, with the
   exception  of  military  tactical  mobile  stations,  Medical  Implant
   Communications Service (MICS) operations. MICS stations are authorized by
   rule on the condition that harmful interference is not caused to stations in
   the   meteorological   aids,   meteorological-satellite,   and   earth
   exploration-satellite services, and that MICS stations accept interference
   from stations in the meteorological aids, meteorological-satellite, and
   earth exploration-satellite services.

   US346  Except as provided for below and by footnote US222, Federal use of
   the band 2025–2110 MHz by the space operation service (Earth-to-space),
   Earth exploration-satellite service (Earth-to-space), and space research
   service  (Earth-to-space)  shall  not  constrain the deployment of the
   Television Broadcast Auxiliary Service, the Cable Television Relay Service,
   or the Local Television Transmission Service. To facilitate compatible
   operations between non-Federal terrestrial receiving stations at fixed sites
   and  Federal  earth station transmitters, coordination is required. To
   facilitate   compatible  operations  between  non-Federal  terrestrial
   transmitting stations and Federal spacecraft receivers, the terrestrial

   (30° 21' 28" N, 87° 16' 26" W). All fixed and fixed satellite operations
   within  80  kilometers of these sites shall be coordinated through the
   Frequency Assignment Subcommittee of the Interdepartmental Radio Advisory
   Committee on a case-by-case basis.

   US349  The band 3650–3700 MHz is also allocated to the Federal radiolocation
   service on a non-interference basis for use by ship stations located at
   least 44 nautical miles in off-shore ocean areas on the condition that
   harmful interference is not caused to non-Federal operations.

   US350  In the band 1427–1432 MHz, Federal use of the land mobile service and

   US356  In the band 13.75–14 GHz, an earth station in the fixed-satellite
   service shall have a minimum antenna diameter of 4.5 m and the e.i.r.p. of
   any emission should be at least 68 dBW and should not exceed 85 dBW. In
   addition the e.i.r.p., averaged over one second, radiated by a station in
   the radiolocation service shall not exceed 59 dBW. Receiving space stations
   in the fixed-satellite service shall not claim protection from radiolocation
   transmitting stations operating in accordance with the United States Table
   of Frequency Allocations. ITU Radio Regulation No. 5.43A does not apply.

   US357  In the band 13.75–14 GHz, geostationary space stations in the space
   research service for which information for advance publication has been
   received by the ITU Radiocommunication Bureau (Bureau) prior to 31 January
   1992 shall operate on an equal basis with stations in the fixed-satellite
   service; after that date, new geostationary space stations in the space
   research  service  will  operate  on  a  secondary  basis. Until those
   geostationary  space  stations in the space research service for which
   information for advance publication has been received by the Bureau prior to
   31 January 1992 cease to operate in this band:

   a.  The  e.i.r.p.  density  of emissions from any earth station in the
   fixed-satellite   service   operating   with   a   space   station  in
   geostationary-satellite orbit shall not exceed 71 dBW in any 6 MHz band from
   13.77 to 13.78 GHz;

   fixed-satellite   service   operating   with   a   space   station  in
   non-geostationary-satellite orbit shall not exceed 51 dBW in any 6 MHz band
   from 13.77 to 13.78 GHz.

   Automatic power control may be used to increase the e.i.r.p. density in any
   6 MHz band in these frequency ranges to compensate for rain attenuation, to
   the extent that the power flux-density at the fixed-satellite service space
   station does not exceed the value resulting from use by an earth station of
   an  e.i.r.p. of 71 dBW or 51 dBW, as appropriate, in any 6 MHz band in
   clear-sky conditions.

   US359  In the band 15.4315.63 GHz, use of the fixed-satellite service
   (Earth-to-space) is limited to non-Federal feeder links of non-geostationary
   systems in the mobile-satellite service. These non-Federal earth stations
   shall be coordinated through the Frequency Assignment Subcommittee (see
   Annex 3 of Recommendation ITU–R S.1340).

   US360  In  the  band  33–36  GHz,  the Federal fixed-satellite service
   (space-to-Earth) is also allocated on a primary basis. Coordination between
   Federal fixed-satellite service systems and non-Federal systems operating in
   accordance  with  the  United States Table of Frequency Allocations is

   such  operations will, insofar as practicable, be adjusted to meet the
   requirements of the aeronautical radionavigation service.

   G19  Use of the band 9000–9200 MHz by military fixed and shipborne air
   defense radiolocation installations will be fully coordinated with the
   aeronautical radionavigation service, recognizing fully the safety aspects
   of the latter. Military air defense installations will be accommodated
   ultimately  outside  this  band.  Until  such time as military defense
   installations can be accommodated satisfactorily elsewhere in the spectrum
   such  operations will, insofar as practicable, be adjusted to meet the

   GHz, all Federal non-military radiolocation shall be secondary to military
   radiolocation,  except  in  the sub-band 15.716.2 GHz airport surface
   detection equipment (ASDE) is permitted on a co-equal basis subject to
   coordination with the military departments.

   G100  The bands 235–322 MHz and 335.4399.9 MHz are also allocated on a
   primary  basis  to  the  mobile-satellite service, limited to military
   operations.

   G104  In the bands 7450–7550 and 8175–8215 MHz, it is agreed that although
   the military space radio communication systems, which include earth stations
   near the proposed meteorological-satellite installations will precede the
   meteorological-satellite installations, engineering adjustments to either

   G118  Federal fixed stations may be authorized in the band 1700–1710 MHz
   only if spectrum is not available in the band 1755–1850 MHz.

   G120  Development of airborne primary radars in the band 2360–2390 MHz with
   peak transmitter power in excess of 250 watts for use in the United States
   is not permitted.

   4940–4990 MHz, Federal operations may be authorized on a non-interference
   basis to authorized non-Federal operations, and shall not constrain the
   implementation of any non-Federal operations.

   G124  The band 2417–2450 MHz was identified for reallocation, effective
   August 10, 1995, for mixed Federal and non-Federal use under Title VI of the

   top

   (a) Pursuant to No. 1492 of Article 13 and Section F of Appendix 3 to the
   international Radio Regulations (Geneva, 1982), operators of radio astronomy
   stations desiring international recognition of their use of specific radio
   astronomy frequencies or bands of frequencies for reception, should file the
   following  information with the Commission for inclusion in the Master
   International Frequency Register:

   (1) The center of the frequency band observed, in kilohertz up to 28,000 kHz
   inclusive, in megahertz above 28,000 kHz to 10,500 MHz inclusive and in
   gigahertz above 10,500 MHz.

   (2) The date (actual or foreseen, as appropriate) when reception of the
   frequency band begins.

   (3) The name and location of the station, including geographical coordinates
   in degrees and minutes.

   (4) The width of the frequency band (in kHz) observed by the station.

   (5) The antenna type and dimensions, effective area and angular coverage in
   azimuth and elevation.

   (6) The regular hours of reception (in UTC) of the observed frequency.

   (7) The overall receiving system noise temperature (in kelvins) referred to
   the output of the receiving antenna.

   (8) The class of observations to be taken. Class A observations are those in
   which the sensitivity of the equipment is not a primary factor. Class B
   observations are those of such a nature that they can be made only with
   advanced low-noise receivers using the best techniques.

   (9) The name and mailing address of the operator.

   (b) The permanent discontinuance of observations, or any change to the
   information above, should also be filed with the Commission.

   (c) Observations being conducted on frequencies or frequency bands not
   allocated to the radio astronomy service should be reported as in paragraph
   (a) of this section for information purposes. Information in this category
   will  not be submitted for entry in the Master International Frequency
   Register  and  protection  from interference will not be afforded such
   operations by stations in other services.

§ 2.108   Policy regarding the use of the fixed-satellite allocations in the
3.6–3.7, 4.5–4.8, and 5.855.925 GHz bands.

   top

   The use of the fixed-satellite allocations in the United States in the above
   bands will be governed by footnote US245. Use of the fixed-satellite service
   allocations in these bands is for the international fixed-satellite service,
   that is, for international inter-continental communications. Case-by-case
   electromagnetic compatibility analysis is required with all users of the
   bands.  It  is anticipated that one earth station on each coast can be
   successfully coordinated. Specific locations of these earth stations depend
   upon service requirements and case-by-case EMC analyses that demonstrate
   compatible operations.

   for  that emission, as given above, shall be preceded by the necessary
   bandwidth of the emission as indicated in §2.202(b)(1).

   [ 49 FR 48697 , Dec. 14, 1984]

§ 2.202   Bandwidths.

   top

   (a) Occupied bandwidth. The frequency bandwidth such that, below its lower
   and above its upper frequency limits, the mean powers radiated are each
   equal to 0.5 percent of the total mean power radiated by a given emission.
   In some cases, for example multichannel frequency-division systems, the
   percentage of 0.5 percent may lead to certain difficulties in the practical
   application of the definitions of occupied and necessary bandwidth; in such
   cases a different percentage may prove useful.

   (b) Necessary bandwidth. For a given class of emission, the minimum value of
   the occupied bandwidth sufficient to ensure the transmission of information
   at the rate and with the quality required for the system employed, under
   specified conditions. Emissions useful for the good functioning of the
   receiving equipment as, for example, the emission corresponding to the
   carrier of reduced carrier systems, shall be included in the necessary
   bandwidth.

   (1) The necessary bandwidth shall be expressed by three numerals and one
   letter. The letter occupies the position of the decimal point and represents
   the unit of bandwidth. The first character shall be neither zero nor K, M or
   G.

   (2) Necessary bandwidths:

   between 0.001 and 999 Hz shall be expressed in Hz (letter H);

   between 1.00 and 999 kHz shall be expressed in kHz (letter K);

   between 1.00 and 999 MHz shall be expressed in MHz (letter M);

   between 1.00 and 999 GHz shall be expressed in GHz (letter G).

   (3) Examples:

   0.002 Hz—H002
   0.1 Hz—H100
   25.3 Hz—25H3
   400 Hz—400H
   2.4 kHz—2K40
   6 kHz—6K00
   12.5 kHz—12K5
   180.4 kHz—180K
   180.5 kHz—181K
   180.7 kHz—181K
   1.25 MHz—1M25
   2 MHz—2M00
   10 MHz—10M0
   202 MHz—202M
   5.65 GHz—5G65

   (c)  The necessary bandwidth may be determined by one of the following
   methods:

   (1) Use of the formulas included in the table, in paragraph (g) of this
   section, which also gives examples of necessary bandwidths and designation
   of corresponding emissions;

   (2) For frequency modulated radio systems which have a substantially linear
   relationship between the value of input voltage to the modulator and the
   resulting frequency deviation of the carrier and which carry either single
   sideband suppressed carrier frequency division multiplex speech channels or
   television, computation in accordance with provisions of paragraph (f) of
   this section and formulas and methods indicated in the table, in paragraph
   (g) of this section;

   (3) Computation in accordance with Recommendations of the International
   Radio Consultative Committee (C.C.I.R.);

   (4) Measurement in cases not covered by paragraph (c) (1), (2), or (3) of
   this section.

   (d) The value so determined should be used when the full designation of an
   emission is required. However, the necessary bandwidth so determined is not
   the only characteristic of an emission to be considered in evaluating the
   interference that may be caused by that emission.

   (e) In the formulation of the table in paragraph (g) of this section, the
   following terms are employed:

   B[n]= Necessary bandwidth in hertz

   B = Modulation rate in bauds

   N = Maximum possible number of black plus white elements to be transmitted
   per second, in facsimile

   M = Maximum modulation frequency in hertz

   C = Sub-carrier frequency in hertz

   D = Peak frequency deviation, i.e., half the difference between the maximum
   and  minimum  values of the instantaneous frequency. The instantaneous
   frequency in hertz is the time rate of change in phase in radians divided by
   2

   t = Pulse duration in seconds at half-amplitude

   t[r]= Pulse rise time in seconds between 10% and 90% of maximum amplitude

   K = An overall numerical factor which varies according to the emission and
   which depends upon the allowable signal distortion.

   N[c]= Number of baseband telephone channels in radio systems employing
   multichannel multiplexing

   P = Continuity pilot sub-carrier frequency (Hz) (continuous signal utilized
   to verify performance of frequency-division multiplex systems).

   (f) Determination of values of D and B [n]for systems specified in paragraph
   (c)(2) of this section:

   (1) Determination of D in systems for multichannel telephony:

   (i) The rms value of the per-channel deviation for the system shall be
   specified.  (In  the  case  of  systems employing preemphasis or phase
   modulation, this value of per-channel deviation shall be specified at the
   characteristic baseband frequency.)

   (ii) The value of D is then calculated by multiplying the rms value of the
   per-channel deviation by the appropriate factors, as follows:
   Number of message circuits Multiplying factors Limits of X (P[avg](dBmO))
   More than 3, but less than 12 4.47×[a factor specified by the equipment
   manufacturer or station licensee, subject to Commission approval]
      3.76 antilog (X+2 log[10]N[c])
   At least 12, but less than 60 ————————————— X: −2to +2.6.
      20
      3.76 antilog (X+4 log[10]N[c])
   At least 60, but less than 240 ————————————— X: −5.6to −1.0.
      20
      3.76 antilog (X+10 log[10]N[c])
   240 or more ————————————— X: −19.6to −15.0.
      20

   Where X represents the average power in a message circuit in dBmO; N[c]is
   the number of circuits in the multiplexed message load; 3.76 corresponds to
   a peak load factor of 11.5 dB.

   (2)  The  necessary  bandwidth  (  B [n]) normally is considered to be
   numerically equal to:

   (i) 2 M +2 DK, for systems having no continuity pilot subcarrier or having a
   continuity pilot subcarrier whose frequency is not the highest modulating
   the main carrier;

   (ii) 2 P +2 DK, for systems having a continuity pilot subcarrier whose
   frequency exceeds that of any other signal modulating the main carrier,
   unless the conditions set forth in paragraph (f)(3) of this section are met.

   (3) As an exception to paragraph (f)(2)(ii) of this section, the necessary
   bandwidth ( B [n]) for such systems is numerically equal to 2 P or 2 M +2 DK
   , whichever is greater, provided the following conditions are met:

   (i) The modulation index of the main carrier due to the continuity pilot
   subcarrier does not exceed 0.25, and

   (ii)  In  a  radio system of multichannel telephony, the rms frequency
   deviation of the main carrier due to the continuity pilot subcarrier does
   not exceed 70 percent of the rms value of the per-channel deviation, or, in
   a radio system for television, the rms deviation of the main carrier due to
   the pilot does not exceed 3.55 percent of the peak deviation of the main
   carrier.

   (ii)  Instead  of  obtaining  a  special temporary authorization or an
   experimental  license,  a  manufacturer  may  operate  its product for
   demonstration or evaluation purposes under the authority of a local FCC
   licensed service provider. However, the licensee must grant permission to
   the manufacturer to operate in this manner. Further, the licensee continues
   to remain responsible for complying with all of the operating conditions and
   requirements associated with its license.

   (4) Marketing, as used in this section, includes sale or lease, or offering
   for sale or lease, including advertising for sale or lease, or importation,
   shipment, or distribution for the purpose of selling or leasing or offering
   for sale or lease.

   (5) Products operating under the provisions of this paragraph (e) shall not
   be recognized to have any vested or recognizable right to continued use of
   any  frequency. Operation is subject to the conditions that no harmful
   interference is caused and that any interference received must be accepted.
   Operation shall be required to cease upon notification by a Commission
   representative that the device is causing harmful interference and shall not
   resume until the condition causing the harmful interference is corrected.

   (f) For radio frequency devices subject to verification and sold solely to

   environment), parties responsible for verification of the devices shall have
   the  option  of  ensuring  compliance  with  the  applicable technical
   specifications  of  this  chapter  at  each  end user's location after
   installation, provided that the purchase or lease agreement includes a
   proviso  that  such  a  determination of compliance be made and is the
   responsibility of the party responsible for verification of the equipment.
   If the purchase or lease agreement contains this proviso and the responsible
   party  has the product measured to ensure compliance at the end user's
   location, the product does not need to be labelled with the statement in
   paragraph (c) of this section.

   (g) The provisions in paragraphs (b) through (f) of this section apply only
   to  devices  that  are designed to comply with, and to the best of the
   responsible party's knowledge will, upon testing, comply with all applicable
   requirements in this chapter. The provisions in paragraphs (b) through (f)
   of this section do not apply to radio frequency devices that could not be
   authorized or legally operated under the current rules. Such devices shall
   not be operated, advertised, displayed, offered for sale or lease, sold or
   leased, or otherwise marketed absent a license issued under part 5 of this
   chapter or a special temporary authorization issued by the Commission.

   (h) The provisions in subpart K of this part continue to apply to imported
   radio frequency devices.

§ 2.925   Identification of equipment.

   top

   (a) Each equipment covered in an application for equipment authorization
   shall bear a nameplate or label listing the following:

   (1)  FCC  Identifier consisting of the two elements in the exact order
   specified in §2.926. The FCC Identifier shall be preceded by the term FCC ID
   in capital letters on a single line, and shall be of a type size large
   enough to be legible without the aid of magnification.

   Example:   FCC ID XXX123. XXX—Grantee Code 123—Equipment Product Code

   (2) Any other statements or labeling requirements imposed by the rules
   governing the operation of the specific class of equipment, except that such
   statement(s) of compliance may appear on a separate label at the option of
   the applicant/grantee.

   (3) Equipment subject only to registration will be identified pursuant to
   part 68 of this chapter.

   (b) Any device subject to more than one equipment authorization procedure
   may be assigned a single FCC Identifier. However, a single FCC Identifier is
   required to be assigned to any device consisting of two or more sections
   assembled in a common enclosure, on a common chassis or circuit board, and
   with common frequency controlling circuits. Devices to which a single FCC
   Identifier has been assigned shall be identified pursuant to paragraph (a)
   of this section.

   (1) Separate FCC Identifiers may be assigned to a device consisting of two
   or  more  sections assembled in a common enclosure, but constructed on
   separate sub-units or circuit boards with independent frequency controlling
   circuits. The FCC Identifier assigned to any transmitter section shall be
   preceded by the term TX FCC ID, the FCC Identifier assigned to any receiver
   section shall be preceded by the term RX FCC ID and the identifier assigned
   to any remaining section(s) shall be preceded by the term FCC ID .

   (2) Where telephone equipment subject to part 68 of this chapter, and a
   radiofrequency device subject to equipment authorization requirements are
   assembled in a common enclosure, the nameplate/label shall display the FCC
   Registration  Number  in  the  format specified in part 68 and the FCC
   Identifier in the format specified in paragraph (a) of this section.

   (3) Applications filed on or after May 1, 1981, and applications filed
   earlier  requesting equipment authorization using the single system of
   identification pursuant to section (a)(1) will receive a review of the
   identification  portion by the Commission's Laboratory with respect to
   nameplate/label design within 30 days after receipt at the Laboratory.
   Failure by the Laboratory to reject a nameplate design proposed in any
   particular application within this time period will constitute de-facto
   acceptance of the nameplate/label design for that particular equipment. Such
   de  facto  acceptance  will be limited to the equipment covered by the
   particular application and will not be considered to establish a precedent
   for other applications. This review deadline applies only to the proposed
   nameplate/label design, not to the remainder of the application.

   (4)  For  a  transceiver,  the receiver portion of which is subject to
   verification  pursuant  to §15.101 of this chapter, the FCC Identifier
   required for the transmitter portion shall be preceded by the term FCC ID .

   (c) [Reserved]

   (d) In order to validate the grant of equipment authorization, the nameplate
   or label shall be permanently affixed to the equipment and shall be readily
   visible to the purchaser at the time of purchase.

   (1) As used here, permanently affixed means that the required nameplate data
   is etched, engraved, stamped, indelibly printed, or otherwise permanently
   marked  on  a  permanently  attached  part of the equipment enclosure.
   Alternatively, the required information may be permanently marked on a
   nameplate of metal, plastic, or other material fastened to the equipment
   enclosure by welding, riveting, etc., or with a permanent adhesive. Such a
   nameplate must be able to last the expected lifetime of the equipment in the
   environment in which the equipment will be operated and must not be readily
   detachable.

   (2) As used here, readily visible means that the nameplate or nameplate data
   must  be  visible  from  the outside of the equipment enclosure. It is
   preferable that it be visible at all times during normal installation or
   use, but this is not a prerequisite for grant of equipment authorization.

   (e) A software defined radio may be equipped with a means such as a user
   display screen to display the FCC identification number normally contained
   in the nameplate or label. The information must be readily accessible, and
   the user manual must describe how to access the electronic display.

   (f) Where it is shown that a permanently affixed nameplate is not desirable
   or is not feasible, an alternative method of positively identifying the
   equipment  may  be  used  if  approved by the Commission. The proposed
   alternative method of identification and the justification for its use must
   be included with the application for equipment authorization.

   Note: As an example, a device intended to be implanted within the body of a
   test  animal  or  person would probably require an alternate method of
   identification.

   (g) The term FCC ID and the coded identification assigned by the Commission
   shall be in a size of type large enough to be readily legible, consistent
   with the dimensions of the equipment and its nameplate. However, the type
   size for the FCC Identifier is not required to be larger than eight-point.

   Internet at https://gullfoss2.fcc.gov/prod/oet/cf/eas/index.cfm. The code
   may  be obtained at any time prior to submittal of the application for
   equipment  authorization. However, the fee required by §1.1103 of this
   chapter must be submitted and validated within 30 days of the issuance of
   the grantee code, or the code will be removed from the Commission's records
   and a new grantee code will have to be obtained.

   (1) After assignment of a grantee code each grantee will continue to use the
   same grantee code for subsequent equipment authorization applications.

   In the event the grantee name is changed or ownership is transferred, the
   circumstances shall be reported to the Commission so that a new grantee code
   can  be assigned, if appropriate. See §§2.934 and 2.935 for additional
   information.

   (2) [Reserved]

   (d) The equipment product code assigned by the grantee shall consist of a
   series of Arabic numerals, capital letters or a combination thereof, and may
   include  the dash or hyphen (-). The total of Arabic numerals, capital
   letters and dashes or hyphens shall not exceed 14 and shall be one which has
   not been previously used in conjunction with:

   (1) The same grantee code, or

   (2) An application denied pursuant to §2.919 of this chapter.

   (e) No FCC Identifier may be used on equipment to be marketed unless that
   specific identifier has been validated by a grant of equipment authorization
   issued  by the Commission. This shall not prohibit placement of an FCC
   identifier on a transceiver which includes a verified receiver subject to
   §15.101,  provided that the transmitter portion of such transceiver is
   covered  by a valid grant of type acceptance or certification. The FCC
   Identifier is uniquely assigned to the grantee and may not be placed on the
   equipment without authorization by the grantee. See §2.803 for conditions
   applicable to the display at trade shows of equipment which has not been
   granted  equipment authorization where such grant is required prior to
   marketing. Labelling of such equipment may include model or type numbers,
   but shall not include a purported FCC Identifier.

§ 2.962   Requirements for Telecommunication Certification Bodies.

   top

   (a)  Telecommunication  certification  bodies (TCBs) designated by the
   Commission, or designated by another authority pursuant to an effective
   bilateral or multilateral mutual recognition agreement or arrangement to
   which  the  United  States is a party, shall comply with the following
   requirements.

   (b) Certification methodology. (1) The certification system shall be based
   on type testing as identified in sub-clause 1.2(a) of ISO/IEC Guide 65.

   (2)  Certification shall normally be based on testing no more than one
   unmodified  representative  sample  of  each  product  type  for which
   certification is sought. Additional samples may be requested if clearly
   warranted,  such  as  when certain tests are likely to render a sample
   inoperative.

   (c) Criteria for Designation. (1) To be designated as a TCB under this
   section,  an  entity  shall,  by  means of accreditation, meet all the
   appropriate specifications in ISO/IEC Guide 65 for the scope of equipment it
   will certify. The accreditation shall specify the group of equipment to be
   certified and the applicable regulations for product evaluation.

   (2) The TCB shall demonstrate expert knowledge of the regulations for each
   product with respect to which the body seeks designation. Such expertise
   shall  include  familiarity with all applicable technical regulations,
   administrative provisions or requirements, as well as the policies and
   procedures used in the application thereof.

   (3) The TCB shall have the technical expertise and capability to test the
   equipment it will certify and shall also be accredited in accordance with
   ISO/IEC Standard 17025 to demonstrate it is competent to perform such tests.

   (4) The TCB shall demonstrate an ability to recognize situations where
   interpretations of the regulations or test procedures may be necessary. The
   appropriate key certification and laboratory personnel shall demonstrate a
   knowledge  of  how  to obtain current and correct technical regulation
   interpretations. The competence of the Telecommunication Certification Body
   shall be demonstrated by assessment. The general competence, efficiency,
   experience, familiarity with technical regulations and products included in
   those technical regulations, as well as compliance with applicable parts of
   the ISO/IEC Standard 17025 and Guide 65, shall be taken into consideration.

   (5) A TCB shall participate in any consultative activities, identified by
   the  Commission  or  NIST,  to  facilitate  a common understanding and
   interpretation of applicable regulations.

   (6) The Commission will provide public notice of the specific methods that
   will be used to accredit TCBs, consistent with these qualification criteria.

   (7) A TCB shall be reassessed for continued accreditation on intervals not
   exceeding two years.

   (d) Sub-contractors. (1) In accordance with the provisions of sub-clause 4.4
   of ISO/IEC Guide 65, the testing of a product, or a portion thereof, may be
   performed by a sub-contractor of a designated TCB, provided the laboratory
   has  been  assessed by the TCB as competent and in compliance with the
   applicable provisions of ISO/IEC Guide 65 and other relevant standards and
   guides.

   (2) When a subcontractor is used, the TCB shall be responsible for the test
   results and shall maintain appropriate oversight of the subcontractor to
   ensure  reliability  of the test results. Such oversight shall include
   periodic audits of products that have been tested.

   (e) Designation of a TCB. (1) The Commission will designate as a TCB any
   organization that meets the qualification criteria and is accredited by NIST
   or its recognized accreditor.

   (2) The Commission will withdraw the designation of a TCB if the TCB's
   accreditation by NIST or its recognized accreditor is withdrawn, if the
   Commission determines there is just cause for withdrawing the designation,
   or  if  the  TCB  requests that it no longer hold the designation. The
   Commission  will provide a TCB with 30 days notice of its intention to
   withdraw the designation and provide the TCB with an opportunity to respond.

   (3) A list of designated TCBs will be published by the Commission.

   (f) Scope of responsibility. (1) A TCB shall certify equipment in accordance
   with the Commission's rules and policies.

   (2)  A  TCB  shall  accept  test  data from any source, subject to the
   requirements in ISO/IEC Guide 65, and shall not unnecessarily repeat tests.

   (3)  A  TCB may establish and assess fees for processing certification
   applications and other tasks as required by the Commission.

   (4) A TCB may rescind a grant of certification within 30 days of grant for
   administrative errors. After that time, a grant can only be revoked by the
   Commission through the procedures in §2.939 of this part. A TCB shall notify
   both the applicant and the Commission when a grant is rescinded.

   (5) A TCB may not:

   (i)  Grant  a  waiver of the rules, or certify equipment for which the
   Commission rules or requirements do not exist or for which the application
   of the rules or requirements is unclear.

   (ii) Take enforcement actions; or

   (iii) Authorize a transfer of control of a grantee.

   (6) All TCB actions are subject to Commission review.

   (g) Post-certification requirements. (1) A TCB shall supply an electronic
   copy of each approved application form and grant of certification to the
   Commission.

   (2)  In accordance with ISO/IEC Guide 65, a TCB is required to conduct
   appropriate post-market surveillance activities. These activities shall be
   based on type testing a few samples of the total number of product types
   which the certification body has certified. Other types of surveillance
   activities of a product that has been certified are permitted, provided they
   are  no more onerous than testing type. The Commission may at any time
   request a list of products certified by the certification body and may
   request and receive copies of product evaluation reports. The Commission may
   also request that a TCB perform post-market surveillance, under Commission
   guidelines, of a specific product it has certified.

   (3)  If  during post market surveillance of a certified product, a TCB
   determines that a product fails to comply with the applicable technical
   regulations, the Telecommunication Certification Body shall immediately
   notify the grantee and the Commission. A follow-up report shall also be
   provided within thirty days of the action taken by the grantee to correct
   the situation.

   (4) Where concerns arise, the TCB shall provide a copy of the application
   file to the Commission within 30 calendar days of a request for the file
   made by the Commission to the TCB and the manufacturer. Where appropriate,
   the file should be accompanied by a request for confidentiality for any
   material that may qualify for confidential treatment under the Commission's
   Rules. If the application file is not provided within 30 calendar days, a
   statement  shall  be provided to the Commission as to why it cannot be
   provided.

   (h) In case of a dispute with respect to designation or recognition of a TCB
   and the testing or certification of products by a TCB, the Commission will
   be the final arbiter. Manufacturers and designated TCBs will be afforded at
   least 30 days to comment before a decision is reached. In the case of a TCB
   designated or recognized, or a product certified pursuant to an effective
   bilateral or multilateral mutual recognition agreement or arrangement (MRA)
   to which the United States is a party, the Commission may limit or withdraw
   its  recognition  of  a  TCB designated by an MRA party and revoke the
   certification of products using testing or certification provided by such a
   TCB. The Commission shall consult with the Office of the United States Trade
   Representative (USTR), as necessary, concerning any disputes arising under
   an MRA for compliance with the Telecommunications Trade Act of 1988 (Section
   1371–1382 of the Omnibus Trade and Competitiveness Act of 1988).

§ 2.1043   Changes in certificated equipment.

   top

   (a) Except as provided in paragraph (b)(3) of this section, changes to the
   basic frequency determining and stabilizing circuitry (including clock or
   data rates), frequency multiplication stages, basic modulator circuit or
   maximum power or field strength ratings shall not be performed without
   application  for  and  authorization  of a new grant of certification.
   Variations  in electrical or mechanical construction, other than these
   indicated items, are permitted provided the variations either do not affect
   the  characteristics  required to be reported to the Commission or the
   variations are made in compliance with the other provisions of this section.
   Changes to the software installed in a transmitter that do not affect the
   radio frequency emissions do not require a filing with the Commission and
   may be made by parties other than the holder of the grant of certification.

   (b)  Three  classes  of permissive changes may be made in certificated
   equipment  without  requiring  a  new  application  for  and  grant of
   certification. None of the classes of changes shall result in a change in
   identification.

   (1)  A  Class  I permissive change includes those modifications in the
   equipment  which  do  not  degrade the characteristics reported by the
   manufacturer and accepted by the Commission when certification is granted.
   No filing with the Commission is required for a Class I permissive change.

   (2) A Class II permissive change includes those modifications which degrade
   the performance characteristics as reported to the Commission at the time of
   the initial certification. Such degraded performance must still meet the
   minimum requirements of the applicable rules. When a Class II permissive
   change is made by the grantee, the grantee shall supply the Commission with
   complete  information  and the results of tests of the characteristics
   affected by such change. The modified equipment shall not be marketed under
   the  existing  grant  of certification prior to acknowledgement by the
   Commission that the change is acceptable.

   (3) A Class III permissive change includes modifications to the software of
   a  software defined radio transmitter that change the frequency range,
   modulation type or maximum output power (either radiated or conducted)
   outside the parameters previously approved, or that change the circumstances
   under which the transmitter operates in accordance with Commission rules.
   When a Class III permissive change is made, the grantee shall supply the
   Commission with a description of the changes and test results showing that
   the equipment complies with the applicable rules with the new software
   loaded, including compliance with the applicable RF exposure requirements.
   The  modified software shall not be loaded into the equipment, and the
   equipment  shall  not be marketed with the modified software under the
   existing grant of certification, prior to acknowledgement by the Commission
   that the change is acceptable. Class III changes are permitted only for
   equipment in which no Class II changes have been made from the originally
   approved device.

   Note to paragraph (b)(3): Any software change that degrades spurious and
   out-of-band emissions previously reported to the Commission at the time of
   initial  certification  would  be  considered a change in frequency or
   modulation and would require a Class III permissive change or new equipment
   authorization application.

   (4) Class I and Class II permissive changes may only be made by the holder
   of the grant of certification, except as specified below.

   (c) A grantee desiring to make a change other than a permissive change shall
   file an application on FCC Form 731 accompanied by the required fees. The
   grantee  shall  attach a description of the change(s) to be made and a
   statement  indicating  whether the change(s) will be made in all units
   (including previous production) or will be made only in those units produced
   after the change is authorized.

   (d) A modification which results in a change in the identification of a
   device with or without change in circuitry requires a new application for,
   and  grant of certification. If the changes affect the characteristics
   required to be reported, a complete application shall be filed. If the
   characteristics required to be reported are not changed the abbreviated
   procedure of §2.933 may be used.

   (e) Equipment that has been certificated or formerly type accepted for use
   in the Amateur Radio Service pursuant to the requirements of part 97 of this
   chapter  may be modified without regard to the conditions specified in
   paragraph (b) of this section, provided the following conditions are met:

   (1) Any person performing such modifications on equipment used under part 97
   of this chapter must possess a valid amateur radio operator license of the
   class required for the use of the equipment being modified.

   (2) Modifications made pursuant to this paragraph are limited to equipment
   used at licensed amateur radio stations.

   (3) Modifications specified or performed by equipment manufacturers or
   suppliers must be in accordance with the requirements set forth in paragraph
   (b) of this section.

   (4) Modifications specified or performed by licensees in the Amateur Radio
   Service on equipment other than that at specific licensed amateur radio
   stations must be in accordance with the requirements set forth in paragraph
   (b) of this section.

   (5) The station licensee shall be responsible for ensuring that modified
   equipment used at his station will comply with the applicable technical
   standards in part 97 of this chapter.

   (f) For equipment other than that operating under parts 15 or 18, when a
   Class  II  permissive  change  is  made  by  other than the grantee of
   certification, the information and data specified in paragraph (b)(2) of
   this section shall be supplied by the person making the change. The modified
   equipment shall not be operated under an authorization of the Commission
   prior to acknowledgement by the Commission that the change is acceptable.

   (g) The interconnection of a certificated or formerly type accepted AM
   broadcast stereophonic exciter-generator with a certificated or formerly
   type accepted AM broadcast transmitter in accordance with the manufacturer's
   instructions and upon completion of measurements showing that the modified
   transmitter meets the emission limitation requirements of §73.44 is defined
   as a Class I permissive change for compliance with this section.

   (h) The interconnection of a multiplexing exciter with a certificated or
   formerly type accepted AM broadcast transmitter in accordance with the
   manufacturer's instructions without electrical or mechanical modification of
   the  transmitter  circuits  and  completion  of  equipment performance
   measurements  showing  the  transmitter  meets the minimum performance
   requirements applicable thereto is defined as a Class I permissive change
   for compliance with this section.

   (i) The addition of TV broadcast subcarrier generators to a certificated or
   formerly  type accepted TV broadcast transmitter or the addition of FM
   broadcast subcarrier generators to a type accepted FM broadcast transmitter,
   provided  the transmitter exciter is designed for subcarrier operation
   without  mechanical  or electrical alterations to the exciter or other
   transmitter circuits.

   (j) The addition of TV broadcast stereophonic generators to a certificated
   or formerly type accepted TV broadcast transmitter or the addition of FM
   broadcast  stereophonic  generators to a certificated or formerly type
   accepted FM broadcast transmitter, provided the transmitter exciter is
   designed for stereophonic sound operation without mechanical or electrical
   alterations to the exciter or other transmitter circuits.

   (k) The addition of subscription TV encoding equipment for which the FCC has
   granted advance approval under the provisions of §2.1400 in subpart M and
   §73.644(c)  of  part  73  to  a certificated or formerly type accepted
   transmitter is considered a Class I permissive change.

   (l) Notwithstanding the provisions of this section, broadcast licensees or
   permittees are permitted to modify certificated or formerly type accepted
   equipment pursuant to §73.1690 of the FCC's rules.

§ 2.1046   Measurements required: RF power output.

   top

   (a) For transmitters other than single sideband, independent sideband and
   controlled carrier radiotelephone, power output shall be measured at the RF
   output terminals when the transmitter is adjusted in accordance with the
   tune-up procedure to give the values of current and voltage on the circuit
   elements specified in §2.1033(c)(8). The electrical characteristics of the
   radio frequency load attached to the output terminals when this test is made
   shall be stated.

   (b)  For  single  sideband,  independent sideband, and single channel,
   controlled carrier radiotelephone transmitters the procedure specified in
   paragraph  (a) of this section shall be employed and, in addition, the
   transmitter shall be modulated during the test as follows. In all tests, the
   input level of the modulating signal shall be such as to develop rated peak
   envelope power or carrier power, as appropriate, for the transmitter.

   (1) Single sideband transmitters in the A3A or A3J emission modes—by two
   tones  at  frequencies  of  400 Hz and 1800 Hz (for 3.0 kHz authorized
   bandwidth), or 500 Hz and 2100 Hz (3.5 kHz authorized bandwidth), or 500 Hz
   and 2400 Hz (for 4.0 kHz authorized bandwidth), applied simultaneously, the
   input levels of the tones so adjusted that the two principal frequency
   components of the radio frequency signal produced are equal in magnitude.

   (2) Single sideband transmitters in the A3H emission mode—by one tone at a
   frequency of 1500 Hz (for 3.0 kHz authorized bandwidth), or 1700 Hz (for 3.5
   kHz authorized bandwidth), or 1900 Hz (for 4.0 kHz authorized bandwidth),
   the level of which is adjusted to produce a radio frequency signal component
   equal in magnitude to the magnitude of the carrier in this mode.

   (3) As an alternative to paragraphs (b) (1) and (2) of this section other
   tones besides those specified may be used as modulating frequencies, upon a
   sufficient  showing  of need. However, any tones so chosen must not be
   harmonically related, the third and fifth order intermodulation products
   which occur must fall within the −25 dB step of the emission bandwidth
   limitation curve, the seventh and ninth order intermodulation product must
   fall within the 35 dB step of the referenced curve and the eleventh and all

   three independent channels—when modulated by the full complement of signals
   for which the transmitter is rated. The level of modulation for each channel
   should be set to that prescribed in rule parts applicable to the services

   sideband, independent sideband, and controlled carrier transmitters shall be
   modulated under the conditions specified in paragraph (c) of §2.1049, as
   appropriate. For equipment operating on frequencies below 890 MHz, an open
   field test is normally required, with the measuring instrument antenna
   located in the far-field at all test frequencies. In the event it is either
   impractical or impossible to make open field measurements (e.g. a broadcast
   transmitter installed in a building) measurements will be accepted of the
   equipment  as  installed.  Such  measurements must be accompanied by a
   description  of  the site where the measurements were made showing the
   location of any possible source of reflections which might distort the field
   strength measurements. Information submitted shall include the relative
   radiated power of each spurious emission with reference to the rated power
   output of the transmitter, assuming all emissions are radiated from halfwave
   dipole antennas.

   (b) The measurements specified in paragraph (a) of this section shall be
   made for the following equipment:

   (1) Those in which the spurious emissions are required to be 60 dB or more
   below the mean power of the transmitter.

   Radio Broadcast Services under part 73 of this chapter.

   (b) Frequency measurements shall be made at the extremes of the specified
   temperature range and at intervals of not more than 10° centigrade through
   the range. A period of time sufficient to stabilize all of the components of
   the oscillator circuit at each temperature level shall be allowed prior to
   frequency measurement. The short term transient effects on the frequency of
   the transmitter due to keying (except for broadcast transmitters) and any
   heating element cycling normally occurring at each ambient temperature level
   also  shall  be shown. Only the portion or portions of the transmitter
   containing the frequency determining and stabilizing circuitry need be
   subjected to the temperature variation test.

   (c) In addition to all other requirements of this section, the following
   information is required for equipment incorporating heater type crystal
   oscillators to be used in mobile stations, for which type acceptance is
   first requested after March 25, 1974, except for battery powered, hand
   carried, portable equipment having less than 3 watts mean output power.

   stabilization  at  each  of  the ambient temperature levels; the lower
   temperature limit, 0° centigrade and +30° centigrade with no primary power
   applied.

   (2) Beginning at each temperature level specified in paragraph (c)(1) of
   this  section, the frequency shall be measured within one minute after
   application of primary power to the transmitter and at intervals of no more
   than  one  minute  thereafter  until ten minutes have elapsed or until
   sufficient measurements are obtained to indicate clearly that the frequency
   has stabilized within the applicable tolerance, whichever time period is
   greater. During each test, the ambient temperature shall not be allowed to
   rise  more  than 10° centigrade above the respective beginning ambient
   temperature level.

   (3) The elapsed time necessary for the frequency to stabilize within the
   applicable  tolerance from each beginning ambient temperature level as
   determined from the tests specified in this paragraph shall be specified in
   the instruction book for the transmitter furnished to the user.

   (4) When it is impracticable to subject the complete transmitter to this
   test because of its physical dimensions or power rating, only its frequency
   determining and stabilizing portions need be tested.

   (d) The frequency stability shall be measured with variation of primary
   supply voltage as follows:

   (1) Vary primary supply voltage from 85 to 115 percent of the nominal value
   for other than hand carried battery equipment.

   (2) For hand carried, battery powered equipment, reduce primary supply
   voltage to the battery operating end point which shall be specified by the
   manufacturer.

   (3) The supply voltage shall be measured at the input to the cable normally
   provided with the equipment, or at the power supply terminals if cables are
   not normally provided. Effects on frequency of transmitter keying (except
   for broadcast transmitters) and any heating element cycling at the nominal
   supply voltage and at each extreme also shall be shown.

   (e) When deemed necessary, the Commission may require tests of frequency
   stability under conditions in addition to those specifically set out in

§ 2.1091   Radiofrequency radiation exposure evaluation: mobile devices.

   top

   (a)  Requirements  of  this  section  are  a consequence of Commission
   responsibilities under the National Environmental Policy Act to evaluate the
   environmental significance of its actions. See subpart I of part 1 of this
   chapter, in particular §1.1307(b).

   (b)  For  purposes  of  this  section, a mobile device is defined as a
   transmitting device designed to be used in other than fixed locations and to
   generally be used in such a way that a separation distance of at least 20
   centimeters is normally maintained between the transmitter's radiating
   structure(s) and the body of the user or nearby persons. In this context,
   the term “fixed location” means that the device is physically secured at one
   location  and  is  not  able  to  be easily moved to another location.
   Transmitting devices designed to be used by consumers or workers that can be
   easily re-located, such as wireless devices associated with a personal
   computer, are considered to be mobile devices if they meet the 20 centimeter
   separation requirement.

   (c) Mobile devices that operate in the Cellular Radiotelephone Service, the
   Personal Communications Services, the Satellite Communications Services, the
   General  Wireless  Communications Service, the Wireless Communications
   Service, the Maritime Services and the Specialized Mobile Radio Service
   authorized under subpart H of part 22 of this chapter, parts 24, 25, 26 and
   27 of this chapter, part 80 of this chapter (ship earth stations devices
   only) and part 90 of this chapter are subject to routine environmental
   evaluation for RF exposure prior to equipment authorization or use if they
   operate at frequencies of 1.5 GHz or below and their effective radiated
   power (ERP) is 1.5 watts or more, or if they operate at frequencies above
   1.5 GHz and their ERP is 3 watts or more. Unlicensed personal communications
   service devices, unlicensed millimeter wave devices and unlicensed NII
   devices authorized under §§15.253, 15.255, and 15.257, and subparts D and E
   of  part  15 of this chapter are also subject to routine environmental
   evaluation for RF exposure prior to equipment authorization or use if their
   ERP is 3 watts or more or if they meet the definition of a portable device
   as specified in §2.1093(b) requiring evaluation under the provisions of that
   section.  All  other  mobile  and  unlicensed transmitting devices are
   categorically excluded from routine environmental evaluation for RF exposure
   prior to equipment authorization or use, except as specified in §§1.1307(c)
   and 1.1307(d) of this chapter. Applications for equipment authorization of
   mobile and unlicensed transmitting devices subject to routine environmental
   evaluation must contain a statement confirming compliance with the limits
   specified in paragraph (d) of this section as part of their application.
   Technical information showing the basis for this statement must be submitted
   to the Commission upon request.

   (d) The limits to be used for evaluation are specified in §1.1310 of this
   chapter. All unlicensed personal communications service (PCS) devices and
   unlicensed  NII  devices  shall  be  subject to the limits for general
   population/uncontrolled exposure.

   (1)  For  purposes  of analyzing mobile transmitting devices under the
   occupational/controlled criteria specified in §1.1310 of this chapter,
   time-averaging provisions of the guidelines may be used in conjunction with
   typical maximum duty factors to determine maximum likely exposure levels.

   (2)  Time-averaging  provisions may not be used in determining typical
   exposure  levels  for devices intended for use by consumers in general
   population/uncontrolled environments as defined in §1.1310 of this chapter.
   However, “source-based” time-averaging based on an inherent property or
   duty-cycle of a device is allowed. An example of this is the determination
   of  exposure  from  a  device  that  uses digital technology such as a
   time-division multiple-access (TDMA) scheme for transmission of a signal. In
   general, maximum average power levels must be used to determine compliance.

   (3) If appropriate, compliance with exposure guidelines for devices in this
   section can be accomplished by the use of warning labels and by providing
   users  with  information  concerning minimum separation distances from
   transmitting structures and proper installation of antennas.

   (4) In some cases, e.g., modular or desktop transmitters, the potential
   conditions of use of a device may not allow easy classification of that
   device as either mobile or portable (also see §2.1093). In such cases,
   applicants are responsible for determining minimum distances for compliance
   for the intended use and installation of the device based on evaluation of
   either specific absorption rate (SAR), field strength or power density,
   whichever is most appropriate.

§ 2.1093   Radiofrequency radiation exposure evaluation: portable devices.

   top

   (a)  Requirements  of  this  section  are  a consequence of Commission
   responsibilities under the National Environmental Policy Act to evaluate the
   environmental significance of its actions. See subpart I of part 1 of this
   chapter, in particular §1.1307(b).

   (b)  For  purposes  of this section, a portable device is defined as a
   transmitting device designed to be used so that the radiating structure(s)
   of the device is/are within 20 centimeters of the body of the user.

   (c) Portable devices that operate in the Cellular Radiotelephone Service,
   the Personal Communications Service (PCS), the Satellite Communications
   Services,  the  General  Wireless Communications Service, the Wireless
   Communications Service, the Maritime Services, the Specialized Mobile Radio
   Service, the 4.9 GHz Band Service, the Wireless Medical Telemetry Service
   (WMTS) and the Medical Implant Communications Service (MICS), authorized
   under subpart H of part 22 of this chapter, parts 24, 25, 26, 27, 80 and 90
   of this chapter, subparts H and I of part 95 of this chapter, and unlicensed
   personal communication service, unlicensed NII devices and millimeter wave
   devices authorized under subparts D and E, §§15.253, 15.255 and 15.257 of
   this chapter are subject to routine environmental evaluation for RF exposure
   prior to equipment authorization or use. All other portable transmitting
   devices are categorically excluded from routine environmental evaluation for
   RF exposure prior to equipment authorization or use, except as specified in
   §§1.1307(c)  and 1.1307(d) of this chapter. Applications for equipment
   authorization  of  portable  transmitting  devices  subject to routine
   environmental evaluation must contain a statement confirming compliance with
   the limits specified in paragraph (d) of this section as part of their
   application. Technical information showing the basis for this statement must
   be submitted to the Commission upon request.

   (d) The limits to be used for evaluation are based generally on criteria
   published by the American National Standards Institute (ANSI) for localized
   specific absorption rate (“SAR”) in Section 4.2 of “IEEE Standard for Safety
   Levels with Respect to Human Exposure to Radio Frequency Electromagnetic
   Fields, 3 kHz to 300 GHz,” ANSI/IEEE C95.1–1992, Copyright 1992 by the
   Institute of Electrical and Electronics Engineers, Inc., New York, New York
   10017. These criteria for SAR evaluation are similar to those recommended by
   the National Council on Radiation Protection and Measurements (NCRP) in
   “Biological Effects and Exposure Criteria for Radiofrequency Electromagnetic
   Fields,” NCRP Report No. 86, Section 17.4.5. Copyright NCRP, 1986, Bethesda,
   Maryland 20814. SAR is a measure of the rate of energy absorption due to
   exposure to an RF transmitting source. SAR values have been related to
   threshold levels for potential biological hazards. The criteria to be used
   are specified in paragraphs (d)(1) and (d)(2) of this section and shall
   apply for portable devices transmitting in the frequency range from 100 kHz
   to 6 GHz. Portable devices that transmit at frequencies above 6 GHz are to
   be  evaluated  in terms of the MPE limits specified in §1.1310 of this
   chapter. Measurements and calculations to demonstrate compliance with MPE
   field strength or power density limits for devices operating above 6 GHz
   should be made at a minimum distance of 5 cm from the radiating source.

   (1) Limits for Occupational/Controlled exposure: 0.4 W/kg as averaged over
   the whole-body and spatial peak SAR not exceeding 8 W/kg as averaged over
   any 1 gram of tissue (defined as a tissue volume in the shape of a cube).
   Exceptions are the hands, wrists, feet and ankles where the spatial peak SAR
   shall not exceed 20 W/kg, as averaged over an 10 grams of tissue (defined as
   a tissue volume in the shape of a cube). Occupational/Controlled limits
   apply when persons are exposed as a consequence of their employment provided
   these persons are fully aware of and exercise control over their exposure.
   Awareness of exposure can be accomplished by use of warning labels or by
   specific training or education through appropriate means, such as an RF
   safety program in a work environment.

   (2)  Limits for General Population/Uncontrolled exposure: 0.08 W/kg as
   averaged over the whole-body and spatial peak SAR not exceeding 1.6 W/kg as
   averaged over any 1 gram of tissue (defined as a tissue volume in the shape
   of a cube). Exceptions are the hands, wrists, feet and ankles where the
   spatial peak SAR shall not exceed 4 W/kg, as averaged over any 10 grams of
   tissue  (defined  as  a tissue volume in the shape of a cube). General
   Population/Uncontrolled limits apply when the general public may be exposed,
   or when persons that are exposed as a consequence of their employment may
   not be fully aware of the potential for exposure or do not exercise control
   over their exposure. Warning labels placed on consumer devices such as
   cellular telephones will not be sufficient reason to allow these devices to
   be evaluated subject to limits for occupational/controlled exposure in
   paragraph (d)(1) of this section.

   (3) Compliance with SAR limits can be demonstrated by either laboratory
   measurement techniques or by computational modeling. Methodologies and
   references  for  SAR  evaluation  are  described in numerous technical
   publications including “IEEE Recommended Practice for the Measurement of
   Potentially  Hazardous  Electromagnetic Fields—RF and Microwave,” IEEE
   C95.3–1991.

   (4)  For purposes of analyzing portable transmitting devices under the
   occupational/controlled criteria, the time-averaging provisions of the MPE
   guidelines identified in §1.1310 of this chapter can be used in conjunction
   with typical maximum duty factors to determine maximum likely exposure
   levels.

   (5) Time-averaging provisions of the MPE guidelines identified in §1.1310 of
   this chapter may not be used in determining typical exposure levels for
   portable devices intended for use by consumers, such as hand-held cellular
   telephones,    that    are    considered   to   operate   in   general
   population/uncontrolled   environments   as  defined  above.  However,
   “source-based” time-averaging based on an inherent property or duty-cycle of
   a  device is allowed. An example of this would be the determination of
   exposure from a device that uses digital technology such as a time-division
   multiple-access (TDMA) scheme for transmission of a signal. In general,
   maximum average power levels must be used to determine compliance.

§ 2.1201   Purpose.

   top

   (a) In order to carry out its responsibilities under the Communications Act
   and the various treaties and international regulations, and in order to
   promote efficient use of the radio spectrum, the Commission has developed
   technical standards for radio frequency equipment. The technical standards
   applicable to individual types of equipment are found in that part of the
   rules governing the service wherein the equipment is to be operated. In
   addition to the technical standards, the rules governing the service may
   require that such equipment receive an equipment authorization from the
   Commission as a prerequisite for marketing and importing this equipment into
   the U.S.A. The marketing rules, §2.801 et seq., were adopted pursuant to the
   authority in section 302 of the Communications Act of 1934, as amended (47
   U.S.C. 302).

   (b) The rules in this section set out the conditions under which radio
   frequency devices as defined in §2.801 that are capable of causing harmful
   interference to radio communications may be imported into the U.S.A.

   (c) Nothing in this section prevents importers from shipping goods into
   foreign trade zones or Customs bonded warehouses, such as is the prescribed
   procedure under §2.1204(a)(5). Radio frequency devices capable of causing
   harmful interference, however, cannot be withdrawn from these areas except
   in accordance with the provisions of this section.

   other similar unintentional radiators which utilize low level battery power
   and which do not contain provisions for operation while connected to AC
   power lines.

   (b) Unintentional radiators which are exempted from technical standards and
   other requirements as specified in §15.103 of this chapter.

   (c) Radio frequency devices manufactured and assembled in the U.S.A. that
   meet applicable FCC technical standards and which have not been modified or
   received further assembly.

   (d) Radio frequency devices previously properly imported that have been
   exported for repair and re-imported for use.

   (e) Subassemblies, parts, or components of radio frequency devices unless
   they constitute an essentially completed device which requires only the
   addition of cabinets, knobs, speakers, or similar minor attachments before
   marketing or use. Form 740 information will be required to be submitted for
   computer circuit boards that are actually peripheral devices as defined in
   §15.3(r) of this chapter and all devices that, by themselves, are subject to
   FCC marketing rules.

General

   top

§ 2.1501   Introduction.

   top

   The procedure described herein sets forth uniform methods for testing Class
   A,  B  and  S  Emergency Position Indicating Radiobeacons (EPIRBs) for
   compliance with the applicable portions of the FCC Rules and Regulations.
   Other  methods  and  test  results may be used provided they are fully
   documented and deemed by the Commission to yield results equivalent to the
   procedures set forth in this section.

§ 2.1503   Test environment.

   top

   (a) Measurement sites. Radiated emission tests for peak effective radiated
   power  (PERP), spurious emissions and power in the test mode are to be
   performed on an open field test site as shown in Figure 1. The site is to be
   located on level ground with an obstruction-free, 60 m by 52 m, elliptical
   area. The site is to be equipped with an antenna mast capable of adjustment
   from 1 to 4 m. The center of a metal ground plane at least one wavelength in
   diameter at 121.5 MHz (2.47 m) is to be located 30 m from the receiving
   antenna. The ground plane is to have provisions for mounting removable
   quarter-wave verticle elements to produce a monopole antenna at both 121.5
   and 243 MHz with the VSWR of less than 1.5.

   Note: It is desirable that the level of radiated ambient EME at the test
   site be at least 6 dB below the FCC limits applicable to the EPIRB. It is,
   of course, not always possible to meet this condition. If the ambient field
   strength at some frequencies within the specified measurement ranges is too
   high, it is recommended that one or more of the following corrective steps
   be employed:

   (1) Perform measurements in critical frequency bands during hours when
   broadcast  and  other radio stations are off-the-air and ambients from
   industrial equipment are lower.

   (2) Insofar as is possible, orient the axis of an open area test site to
   discriminate against strong ambient signals.

   (3) Vary the bandwidth of the measuring instrument to separate ambient EME
   from emissions from the EPIRB.

   (b) Temperature. Except as otherwise noted, the ambient temperature during
   testing is to be within the range of 4 to 35 °C (40 to 95 °F).

§ 2.1505   Test instrumentation and equipment.

   top

   (a) Receiver (field intensity meter). A calibrated field intensity meter
   (FIM) with a frequency range of 30 to 1000 MHz is required for measuring
   radiated emission levels. This instrument should be capable of making peak
   measurements with a bandwidth of 100 kHz.

   (b) Spectrum analyzer. Spectral measurements are to be made with a spectrum
   analyzer with a minimum resolution bandwidth no greater than 10 Hz. The
   video filter, if used, should have a bandwidth wide enough so as to not
   affect peak readings. A linear video output is desirable for performing
   measurements of modulation characteristics.

   (c) Storage oscilloscope. Measurements of modulation characteristics are to
   be made using a calibrated storage oscilloscope. This instrument is to be DC
   coupled and capable of manually triggered single sweeps.

   (d) Frequency counter. A frequency counter with an accuracy of at least 5
   parts per million is required for measuring the carrier frequency.

   (e) Signal generator. A calibrated signal generator with an output of at
   least 75 mW at 121.5 and 243 MHz is required for generating a reference
   signal for site calibration.

   (f) Antenna. Radiated emissions are to be measured with calibrated, tuned,
   half-wave dipole antennas covering the frequency range of 30 to 1000 MHz.

   (g)  Temperature chamber. Tests which call for subjecting the EPIRB to
   temperature levels other than the ambient temperature are to be performed in
   a temperature test chamber which can be adjusted to stable temperatures from
   −20 to +55 °C. This chamber is to be of sufficient size to accommodate the
   EPIRB under test.

   (h) Vibration table. A vibration table capable of vibrating the EPIRB with a
   sinusoidal motion is required. The table must be capable of varying the
   frequency of vibration either linearly or logarithmically over a range of 4
   to 33 Hz with maximum peak amplitudes of up to 2.5 mm.

   (i)  Salt  fog  chamber.  A chamber capable of producing salt fog at a
   temperature of 35 °C for 48 hours is required. This chamber is to be of
   sufficient size to accommodate the EPIRB under test.

   (j) Drop test facility. A facility which will permit dropping an EPIRB from
   a height of 20 m into water is required. The water must be deep enough so
   that the EPIRB will not touch bottom when dropped.

Environmental and Operational Test Procedures

   top

§ 2.1507   Test frequencies.

   top

   Testing of an EPIRB for compliance outside a shielded room on a distress
   frequency  is  prohibited,  since  this  may  interfere with emergency
   communications. Therefore, all compliance testing outside a shielded room
   should be conducted on one of the pairs of alternate frequencies specified
   below:

   121.600/243.200 MHz

   121.650/243.300 MHz

   121.700/243.400 MHz

   121.750/243.500 MHz

   121.800/243.600 MHz

   121.850/243.700 MHz

   121.900/243.800 MHz

   The above frequencies are to be used for limited testing of EPIRBs for
   compliance with FCC Rules, subject to the following conditions:

   (a)  The  testing  shall  not cause harmful interference to authorized
   communications on these frequencies.

   (b) The testing shall be coordinated with the nearest FCC district office.

   For simplicity, 121.5 MHz and 243 MHz will be used throughout this test
   procedure to indicate the alternate test frequency.

§ 2.1509   Environmental and duration tests.

   top

   The environmental and operational tests in §2.1509 (a) through (e) are to be
   conducted on a single test unit in the order given below. This sequence of
   tests also includes the electrical tests in §§2.1511, 2.1513 and 2.1515 of
   this part. The test unit is not to be adjusted, nor is the battery to be
   replaced  during  these  tests, and a log of battery on-time should be
   maintained. The above tests are to be performed on the same test unit. The
   tests  in §2.1509 (f) through (i) may be run in any sequence or may be
   performed on separate test units.

   (a) Vibration test. 

   Step (1) Secure the EPIRB to the vibration table. The EPIRB is not to be
   operated and should not activate while being vibrated.

   Step (2) Subject the EPIRB to sinusoidal motion parallel to one of the three
   major orthogonal axes under the following conditions:
   A. Frequency (Hz) Peak amplitude (mm)
         4–10                2.5
         10–15               0.8
         15–25               0.4
         25–33               0.2

   B. The frequency is to be changed either linearly or logarithmically with
   time between 4 Hz and 33 Hz such that a complete cycle (4 Hz to 33 Hz to 4
   Hz) takes approximately 5 minutes.

   C. The EPIRB is to be vibrated for at least 30 minutes or six complete
   cycles.

   Step (3) Remount the EPIRB, if necessary, and repeat step 2 for each of the
   other two major orthogonal axes.

   Step  (4)  Upon completion of the test, perform an exterior mechanical
   inspection and verify operation by turning the unit on and observing the RF
   power indicator on the unit or monitoring the transmission with a receiver.
   Record test results.

   (b) Thermal shock tests. These tests are to be performed on EPIRBs which are
   required or intended to float. (1) Low temperature thermal shock test. 

   Step (1) Place the EPIRB in a temperature chamber for at least 3 hours at
   −20 °C or colder. The EPIRB is not to be operated while being cooled.

   Step (2) Immediately place the EPIRB in water that has been maintained at
   +10 °C or warmer.

   Step (3) After 15 minutes, perform as exterior mechanical inspection and
   verify operation by turning the unit on and observing the RF power indicator
   on the unit or monitoring the transmission with a receiver. Record test
   results.

   (2) High temperature thermal shock test. 

   Step (1) Place the EPIRB in a temperature chamber for at least 3 hours at
   +55 degrees C or warmer. The EPIRB is not to be operated while being heated.

   Step (2) Immediately float the EPIRB in water that is maintained at +25
   degrees C or colder.

   Step (3) After 15 minutes, perform an exterior mechanical inspection and
   verify operation by turning the unit on and observing the RF power indicator
   on the unit or monitoring the transmission with a receiver. Record test
   results.

   (c) Salt fog test. 

   Step (1) Place the EPIRB in a salt fog chamber for a period of at least 2
   hours at a temperature of 35 °C (±2 °C) before exposing it to salt fog. The
   EPIRB is to be turned off during this test.

   Step (2) With the chamber temperature maintained at 35 °C, introduce salt
   fog at the saturation point for 48 hours. The salt fog is to be prepared
   from a 5% (±1%) salt (sodium chloride solution. For detailed guidance on the
   preparation of the solution and the apparatus for generating salt fog, refer
   to MIL-STD-810D (19 July 1983), method 509.2.

   Step  (3) Upon completion of the salt fog exposure, the EPIRB is to be
   airdried at room temperature for 12 hours and operation verified by turning
   the unit on and observing the RF power indicator on the unit or monitoring
   the transmission with a receiver. Record observations.

   (d) Drop test. This test is to be performed on EPIRB which are required or
   intended to float.

   Step (1) Turn the EPIRB on, log the time and drop it three times into water
   from a height of 20 meters. The water is to be deep enough so that the EPIRB
   does not touch bottom when dropped. Each drop should be initiated from a
   different orientation as follows: antenna vertical up; antenna vertical
   down; antenna horizontal.

   Step (2) Upon completion of the drop test, an exterior mechanical inspection
   is  to  be  performed and operation verified by observing the RF power
   indicator on the unit or monitoring the transmission with a receiver. Record
   observations. Turn the test unit off and log the total on-time.

   (e) Forty-eight hour operational test. This test includes the battery life
   test and all the electrical tests given in §§2.1511, 2.1513 and 2.1515 of
   this part, at various temperatures. The tests are to be performed on the
   same EPIRB in the sequence specified herein. Be sure to record the on-time
   of the unit during each test. No more than 8 hours of total on-time is
   permitted  before  commencing  step 4. When operating the EPIRB in the
   environmental chamber, a non-radiating load may be substituted for the
   antenna provided it is electrically equivalent to the standard antenna and
   does not reduce the battery current drain.

   Step (1) Perform the radiated emissions test in §2.1511 of this part.

   Step (2) Perform the modulation characteristic tests in §2.1513 of this
   part.

   Step (3) Perform the spectral tests in §2.1515 of this part.

   Step (4) With the EPIRB off, place unit in an environmental chamber at a
   temperature of −20 °C for at least 2 hours.

   Step (5) With the EPIRB in the chamber, repeat the carrier frequency test in
   §2.1515(d) of this part. (Leave the EPIRB turned on.)

   Step (6) Near the end of 48 hours of total on-time for the EPIRB, repeat the
   carrier frequency test in §2.1515(d) of this part.

   Step (7) At the end of 48 hours of total on-time, remove EPIRB from the
   chamber and immediately repeat the PERP test for the fundamental emissions
   in §2.1511(c) of this part. The unit should be maintained at −20 °C to the
   extent possible for this test.

   (f) Float free and activation test. This test is required only for Class A
   EPIRBs.

   Step (1) The EPIRB is to be installed in the automatic release mechanism and
   the assembly is to be mounted on a fixture simulating a deck or bulkhead as
   per manufacturer' installation instructions.

   Step (2) Submerge the fixture in water in its normal mounted orientation.
   The EPIRB must float free before reaching a depth of 4 meters and should
   automatically activate. Activation is to be verified by observing the RF
   power indicator on the unit or monitoring the transmission with a receiver.

   If the EPIRB is equipped with an automatically deployable antenna, the
   antenna must properly deploy during each immersion. Record observations.

   (g) Stability and buoyancy test. This test is to be performed on EPIRBs
   which are required or intended to float. This test is to be conducted in
   fresh water.

   Step  (1)  With the antenna deployed in its normal operating position,
   submerge the EPIRB in a horizontal position just below the surface of the
   water.

   Step (2) Release the EPIRB and observe the amount of time required for it to
   come to an upright position. It must reach its upright position within one
   second from each position.

   The EPIRB must have a reserve buoyancy of at least 5% of its gross weight.
   It must also float upright in calm water with the base of the antenna a
   minimum of 5 cm above the water. Record the time required for the test unit
   to right itself.

   (h) Temperature/frequency test. The frequency stability shall be measured
   over an ambient temperature from −20° to +55 °C at intervals of not more
   than 10 °C. A period of time sufficient to stabilize all of the components
   of the oscillator circuit at each temperture level shall be allowed prior to
   frequency measurement.

   Step (1) Place the EPIRB in the environmental test chamber.

   Step  (2)  Adjust  the  temperature in the chamber to +20 °C and allow
   sufficient time for the oscillator to stabilize at that temperature.

   Step (3) Measure the carrier frequency in accordance with the procedure in
   §2.1515(d) of this part. Record the carrier frequency in Hertz. The carrier
   frequency  at  +20  °C  is the reference for determining the frequency
   tolerance.

   Step  (4)  Increase the temperature in the chamber to +55 °C and allow
   sufficient time for the oscillator to stabilize at that temperature. Measure
   the carrier frequency using the procedure in §2.1515(d) of this part.

   Step (5) Reduce the temperature in the chamber in 10 °C maximum increments
   until −20 °C is reached. At each new temperature, allow sufficient time for
   the oscillator to stabilize at that temperature. Measure the temperature and
   frequency in each case and plot the frequency vs temperature from −20° to
   +55 °C.

   (i) Leakage and immersion test. 

   Step (1) Completely submerge the EPIRB in water for 48 hours. The EPIRB is
   to be turned off during this test.

   Step (2) Remove the EPIRB from the water and wipe dry.

   Step (3) Verify operation by briefly turning the EPIRB on and observing the
   RF  power  indicator on the unit or monitoring the transmission with a
   receiver.

   Step (4) Open the EPIRB for examination. There is to be no water inside the
   unit. Record observations.

§ 2.1511   Measurements of radiated emissions.

   top

   The Commission's Rules require that the peak efficetive radiated power
   (PERP) of a Class A, B or S EPIRB not be less than 75 mW under certain
   specified conditions. The PERP of an EPIRB transmitter is determined by
   comparing its level to a reference PERP generated by a standard quarter-wave
   monopole antenna located on a one wavelength minimum diameter metal ground
   plane. The Rules also require that all spurious and harmonic emissions be
   attenuated by a specified amount with respect to the reference PERP. In
   addition, there is a limit on the PERP of radiated emissions with the switch
   in the test mode. These measurements are to be made in accordance with the
   following procedure.

   (a) General set-up instructions. Measurements of radiated electromagnetic
   emissions (EME) are to be performed on the 30 meter open field test site
   described in §2.1503(a) of this part and on one of the pair of frequencies
   listed in §2.1507 of this part. A receiver, tuned dipole antennas and a
   calibrated  signal  generator as described in §2.1505 of this part are
   required. The EPIRB should be powered by its own internal battery with its
   standard antenna attached and deployed.

   (b) Set-up for radiated EME tests. 

   Step (1) Place a 121.5 MHz quarter-wave vertical antenna element at the
   center of the ground plane and connect the output of the calibrated signal
   generator to the antenna.

   Step  (2) Mount the tuned dipole antenna on the antenna mast, tune the
   elements to 121.5 MHz and connect the antenna to the receiver.

   Step (3) After an appropriate warm up, turn the receiver to the frequency of
   the test unit, set the detector to peak mode and the bandwidth to 100 kHz.

   (Note: It is sometimes helpful to monitor the receiver audio output with a
   speaker. The EPIRB signal may be identified by its distinctive modulation.)

   (c) Radiated EME tests. 

   Fundamental emissions-peak effective radiated power

   Step (1) Turn on the signal generator and adjust the output to 75 mW at
   121.5 MHz.

   Step (2) Vary the antenna height from one to four meters in both vertical
   and horizontal polarization. Record the highest receiver reading in dBm as
   the reference level.

   Step  (3) Disconnect the signal generator and replace the quarter-wave
   vertical element on the ground plane with the EPIRB under test. The EPIRB is
   to be positioned directly on the surface of and in the center of the metal
   ground plane.

   Step (4) Activate the EPIRB.

   Step (5) Vary the receive antenna height from one to four meters in both
   vertical and horizontal polarization. Record the highest receiver reading in
   dBm and the instrument settings, antenna height and direction for maximum
   radiation, antenna polarization and conversion factors, if any, associated
   with that reading.

   Step (6) Repeat Step 5 with the EPIRB switch in the test position. Return
   the switch to the normal operation position.

   Step (7) Rotate the EPIRB 30 degrees and repeat Steps 5 and 6. Repeat this
   step for all successive 30 degrees segments of a full, 360 degree rotation
   of the EPIRB.

   Step (8) Repeat §2.1511(b) and Steps 1 through 7 for 243 MHz.

   Step (9) Compute the peak effective radiated power for the maximum level of
   each measured emission using the following formula:
   [MATH:  :MATH]

   where:

   dBm[meas]is the measured receiver reading in dBm, and

   dBm[ref]is the reference receiver reading found in step 2 of §2.1511(c).

   Step (10) Record the PERP in mW. The FCC limit for minimum power in the
   normal operation mode (i.e., with the EPIRB switch in the normal operating
   position) is 75 mW. The FCC limit for maximum power in the test mode is
   0.0001 mW.

   Spurious emissions

   Step (11) Reset the signal generator to operate at 121.5 MHz.

   Step (12) For each spurious and harmonic emission to be measured, retune the
   receive antenna to the appropriate frequency and repeat Steps 5 and 7.

   Step (13) Determine the FCC limit on power for spurious emissions on the
   frequency of each measured emission as follows:

   The rules require that spurious emissions be attenuated at least 30 decibels
   below the transmit power level. Therefore, the maximum received power limit
   for a spurious emission can be calculated from the formula:

   dBm[spur]= dBm[meas]+AF[121.5]−AF[spurfreq]−30

   where:

   dBm[meas]= measured receiver reading (Section 2.1511(c), step 5).

   AF[121.5]= tuned dipole antenna factor at 121.5 MHz.

   AF[spurfreq]= tuned dipole antenna factor at spurious freq.

   Step (14) Record in dB below the fundamental emissions the level of all
   spurious and harmonic emissions within 10 dB of the FCC limits.

§ 2.1513   Measurements of modulation characteristics.

   top

   (a) Set-up. Test of modulation characteristics are to be performed in an RF
   shielded room.

   Step (1) Place the EPIRB directly on a metal ground plane, such as the
   shielded room floor.

   Step (2) Place a suitable receiving antenna at a convenient distance from
   the EPIRB and connect it to the input of the spectrum analyzer or receiver
   to observe the radiated signal from the EPIRB.

   Step (3) Set the spectrum analyzer or receiver controls as follows:

   I.F. bandwidth: 300 kHz minimum

   Video filter: OFF or as wide as possible

   Amplitude scale: Linear

   Frequency: 121.5 MHz

   Scan width: 0 Hz

   Step (4) Connect the detected output of the spectrum analyzer or receiver to
   the input of the storage oscilloscope.

   Step (5) Set the oscilloscope controls as necessary to allow the demodulated
   waveform to be viewed. The input signal is to be DC coupled.

   (b) Measurement of Audio Frequencies. 

   Step (1) Activate the EPIRB.

   Step (2) Trigger the oscilloscope and store at least one complete cycle of
   the audio waveform.

   Step (3) Measure the period (T) of the waveform. The period is the time
   difference between the half voltage points at the beginning and end of one
   complete cycle of the waveform. See Figure 2.

   Step (4) Calculate the frequency (F), where:

   F=1/T.

   Step  (5)  Repeat Steps 2 through 4 until the highest and lowest audio
   frequencies are found.

   Note: The lowest and highest frequencies may occur several cycles before or
   after the transition from low to high frequency.)

   Step (6) Determine the audio frequency range (F[range]), where:

   F[range]=F[high]−F[low]

   Step  (7)  Record instrument settings and the lowest and highest audio
   frequencies. Record the audio frequency range in Hertz.

   Step (8) Repeat Steps 1–7, above, for 243 MHz.

   (c) Modulation factor. 

   Step (1) Activate the EPIRB.

   Step (2) Trigger the oscilloscope and store at least one complete cycle of
   the  audio waveform. The input signal is to be DC coupled or erroneous
   results will be obtained.

   Step (3) Measure the maximum voltage (V[max]), and the minimum voltage
   (V[min]) for the cycle. The modulation factor (M) is calculated from the
   following formula:
   [MATH:  :MATH]

   See Figure 2.

   Step (4) Repeat Steps 2 and 3 until the lowest modulation factor is found.

   Step  (5) Record instrument settings and the lowest modulation factor,
   expressed as a ratio between 0 and 1.

   Step (6) Repeat the above measurements for 243 MHz.

   (d) Modulation duty cycle. 

   Step (1) Activate the EPIRB.

   Step (2) Trigger the oscilloscope and store at least one complete cycle of
   the audio waveform.

   Step (3) Measure the period (T) of the waveform. The period is the time
   difference between the half voltage points at the beginning and end of one
   cycle of the waveform. See Figure 2.

   Step (4) Measure the pulse width (t[p]) of the waveform. The pulse width is
   the  time difference between the half voltage points on the rising and
   falling portions of the waveform. See Figure 2.

   Step (5) Calculate the duty cycle (D) as follows:
   [MATH:  :MATH]

   Step (6) Repeat Steps 2 through 5 a sufficient number of times to determine
   the highest and lowest duty cycles.

   Step (7) Record instrument settings and the highest and lowest duty cycles
   in percent.

   Step (8) Repeat Steps 1–7 for 243 MHz.

   (e) Sweep repetition rate. 

   Step (1) Connect a speaker to the detected output of the spectrum analyzer
   or receiver so the audio frequencies are audible. Alternatively, an FM radio
   tuned to 108 MHz placed in the vicinity of the EPIRB may be used.

   Step (2) Activate the EPIRB.

   Step (3) Time the number of audio sweeps (N) for a one minute interval.

   Step (4) Calculate the audio sweep rate (R) using R=N/60.

   Step (5) Record instrument settings and the sweep repetition rate in Hertz.

§ 2.1515   Spectral measurements.

   top

   (a) Set-up. Spectral measurements are to be performed in a shielded room.

   Step (1) Place the EPIRB directly on a metal ground plane, such as the
   shielded room floor. The EPIRB should be powered by its own internal battery
   with its standard antenna attached and deployed.

   Step (2) Place a suitable receiving antenna at a convenient distance from
   the EPIRB and connect it to the input of the spectrum analyzer to observe
   the radiated signal from the EPIRB. A signal generator and frequency counter
   capable of operating at 121.5 and 243 MHz are also required for these tests.

   (b) Occupied bandwidth test. 

   Step (1) Activate the EPIRB and observe the fundamental frequency on a
   spectrum  analyzer.  Adjust location of receiving antenna and spectrum
   analyzer controls to obtain a suitable signal level (i.e., a level which
   will not overload the spectrum analyzer, but is far enough above the noise
   floor to allow determination of whether or not the sidebands are attenuated
   by at least the amount required in the rules).

   Step (2) Set spectrum analyzer controls as follows:

   I.F. bandwidth: 10 kHz

   Video filter: OFF or as wide as possible

   Scan time: 100 ms./div.

   Amplitude scale: 10 dB/div.

   Scan width: 20 Hz/div.

   Center frequency: 121.5 MHz

   Step (3) Record the signal level in dbm.

   Step (4) Calculate the mean power reference level by adding 10 log[10](D),
   where D is the modulation duty cycle determined in section 2.1513(d) of this
   part, to the recorded signal level.

   Step (5) Set spectrum analyzer controls as follows:

   I.F. bandwidth: 100 Hz

   Video filter: OFF or as wide as possible

   Scan time: 10 sec./div.

   Amplitude scale: 10 dB/div.

   Scan width: 20 kHz/div.

   Step (6) Check the modulation sidebands for compliance with the required
   attenuation below the mean power reference level specified in §80.211 of the
   rules.

   Step (7) Record how the test was performed, instrument settings and the
   occupied bandwidth in kHz and the 3 dB bandwidth of the carrier in Hz. (See
   §2.1517 of this part).

   Step (8) Repeat Steps 1 through 7 for the signal at 243 MHz.

   (c) Signal enhancement test. The setup specified in §2.1515(a) is to be used
   in this method of measuring signal enhancement. Other methods may be used if
   shown to give results equivalent to or more accurate than this method.

   Step (1) Activate the EPIRB and locate the carrier frequency at 121.5 MHz on
   the spectrum analyzer. Adjust location of receiving antenna and spectrum
   analyzer controls to obtain a suitable signal level (i.e., a level which
   will not overload the analyzer, but is far enough above the noise floor to
   allow sidebands at least 40 dB below the carrier to be viewed).

   Step (2) Set the spectrum analyzer controls as follows:

   I.F. bandwidth: 10 kHz

   Video filter: OFF or as wide as possible

   Scan time: 100 ms./div.

   Amplitude scale: 5 dB/div.

   Scan width: 10 kHz/div.

   Center frequency: 121.5 MHz

   Step (3) Record the amplitude in dBm.

   Step (4) Calculate the total power output by adding 10 log(D), where D is
   the modulation duty cycle determined in §2.1513(d) of this part, to the
   recorded signal level.

   Step (5) Set the spectrum analyzer controls as follows:

   I.F. bandwidth: 60 Hz or less

   Video filter: OFF or as wide as possible

   Scan time: 10 sec./div.

   Amplitude scale: 5 dB/div.

   Scan width: 20 Hz/div.

   Center frequency: 121.5 MHz

   Step  (6) Measure and record the carrier power dBm as displayed on the
   spectrum analyzer.

   Step (7) Calculate the ratio of carrier power to total power from Steps 4
   and 6 using the following formula:
   [ec03jn91.004.gif]

   dB[C]= carrier power in step 6

   dB[T]= total power in step 4

   Step (8) Record instrument settings, sample calculation and the percent of
   power  within  ±30 Hz at 121.5 MHz or ±60 Hz at 243 MHz of the carrier
   frequency.

   Step (9) Repeat the above measurement Steps 1 through 8 for 243 MHz. For the
   higher frequency, the I.F. bandwidth in step 5 must be 120 Hz or less.

   (d) Carrier frequency test. The setup specified in §2.1515(a) is to be used
   in measuring the carrier frequency.

   Step (1) Activate the EPIRB and locate the 121.5 MHz signal on the spectrum
   analyzer.  Adjust  location of receiving antenna and spectrum analyzer
   controls to obtain a suitable signal level.

   Step (2) Set the spectrum analyzer controls as follows:

   I.F. bandwidth: 100 Hz

   Video filter: OFF or as wide as possible

   Scan time: 10 sec./div.

   Amplitude scale: 10 dB/div.

   Scan width: 20 Hz/div.

   Center frequency: 121.5 MHz

   Step (3) Combine the output of the signal generator with the EPIRB signal at
   the input to the spectrum analyzer.

   Step  (4) Adjust amplitude and frequency of signal generator output to
   determine center of carrier frequency component.

   Step (5) Measure signal generator frequency with frequency counter with
   accuracy of 5 PPM or better and record as carrier frequency.

   Step (6) If applicable, change the type of modulation of the EPIRB and
   record the shift in carrier frequency as observed on the spectrum analyzer
   display.

   Step (7) Repeat the above measurement Steps 1 through 6 for 243 MHz.
