   ^1Unlimited hours of use from December 15 to April 1 and day only from
   April 1 to December 15. Harmful interference must not be caused to any
   station in the Great Lakes region.

   ^2In the Great Lakes region 2206 kHz is not available for transmission
   to U.S. ships except in the case of distress. U.S. coast stations in
   the Great Lakes area may use 2514, 2550 and 2582 kHz on a shared basis
   with coast stations of Canada. Except in the case of distress, the
   frequency 2550 kHz must not be used for transmission to ship stations
   of Canada since the associated ship station transmit frequency 2158 kHz
   is not available to Canadian ship stations for transmission and 2582
   kHz must not be used for public correspondence transmissions to U.S.
   ship stations since the associated ship transmit frequency 2206 kHz is
   not available to U.S. ship stations for transmissions except in the
   case of distress.

   ^3Limited to a peak envelope power of 150 watts.

   ^4Harmful interference must not be caused to any coast station in the
   Caribbean region.

   ^5 But see section 80.373(c)(3) of this chapter.

   (b) Working frequencies in the 4000-27500 kHz band. This paragraph
   describes the working carrier frequencies in the 4000-27500 kHz band.
   With respect to frequencies that are assignable in more than one
   geographical area, once the frequency is assigned to one licensee, any
   subsequent license will be authorized on a secondary, non-interference
   basis with respect to the incumbent license's existing operation. If
   the first licensee later seeks authorization to operate in an
   additional geographic area, such authorization will be on a secondary,
   non-interference basis to other co-channel licensees.

   (1) The following table specifies the carrier frequencies available for
   assignment to public coast stations. The paired ship frequencies are
   available for use by authorized ship stations. The specific frequency
   assignment available to public coast stations for a particular
   geographic area is indicated by an "x" under the appropriate column.
   The allotment areas are in accordance with the "Standard Defined Areas"
   as identified in the International Radio Regulations, Appendix 25
   Planning System, and indicated in the preface to the International
   Frequency List (IFL).

   (2) The following table specifies the non-paired carrier frequencies
   that are available for assignment to public coast stations for simplex
   operations. These frequencies are available for use by authorized ship
   stations for transmissions to coast stations (simplex operations).
   Assignments on these frequencies must accept interference. They are
   shared with government users and are considered "common use"
   frequencies under the international Radio Regulations. They cannot be
   notified for inclusion in the Master International Frequency Register,
   which provides stations with interference protection, but may be listed
   in the international List of Coast Stations. ( See Radio Regulation No.
   1220 and Recommendation 304.)

   ^1For special assignment of frequencies in this band in certain areas
   of Washington State, the Great Lakes and the east coast of the United
   States pursuant to arrangements between the United States and Canada,
   see subpart B of this part.

   ^2The frequency pair 157.275/161.875 MHz is available on a primary
   basis to ship and public coast stations. In Alaska it is also available
   on a secondary basis to private mobile repeater stations.

   ^3The frequency 161.975 MHz is available only for Automatic
   Identification System communications. No license authorizing a
   site-based VHF Public Coast Station or a Private Land Mobile Radio
   Station to operate on the frequency 161.975 MHz in VHF Public Coast
   Service Areas (VPCSAs) 1-9 will be renewed unless the license is or has
   been modified to remove frequency 161.975 MHz as an authorized
   frequency. In VPCSAs 10-42, site-based stations licensed to operate on
   frequency 161.975 MHz prior to March 2, 2009 may continue to operate on
   a co-primary basis on that frequency until March 2, 2024. Licenses
   authorizing geographic stations to operate on frequency 161.975 MHz
   will be modified on March 2, 2011 to replace the frequency with either
   frequency pair 157.225/161.825 MHz (VPCSAs 10-15, 23-30, 33-34, 36-39,
   and 41-42) or frequency pair 157.275/161.875 MHz (VPCSAs 16-22, 31-32,
   35, and 40), unless an application to so modify the license is granted
   before that date.

   ^4The frequency 162.025 MHz is available only for Automatic
   Identification System communications. One hundred twenty kilometers (75
   miles) from the United States/Canada border, the frequency 157.425 MHz
   is available for intership and commercial communications. Outside the
   Puget Sound area and its approaches and the Great Lakes, 157.425 MHz is
   available for communications between commercial fishing vessels and
   associated aircraft while engaged in commercial fishing activities.

   ^5In VPCSAs 10-42, the working carrier frequency pair 157.250/161.850
   MHz (Channel 25) is not available for assignment under part 80.

   (ii) Service areas in the marine VHF 156-162 MHz band are VHF Public
   Coast Service Areas (VPCSAs). As listed in the table in this paragraph,
   VPCSAs are based on, and composed of one or more of, the U.S.
   Department of Commerce's 172 Economic Areas (EAs). See  60 FR 13114 
   (March 10, 1995). In addition, the Commission shall treat Guam and the
   Northern Mariana Islands, Puerto Rico and the United States Virgin
   Islands, American Samoa, and the Gulf of Mexico as EA-like areas, and
   has assigned them EA numbers 173-176, respectively. Maps of the EAs and
   VPCSAs are available for public inspection and copying at the FCC
   Public Reference Room, Room CY-A257, 445 12th Street, SW., Washington,
   DC 20554, 1-888-225-5322. In addition to the EAs listed in the table in
   this paragraph, each VPCSA also includes the adjacent waters under the
   jurisdiction of the United States. In VPCSAs 10-42, the working carrier
   frequency pair 157.250 MHz/161.850 MHz (Channel 25) is not available
   for assignment under part 80.

   (iii) Subject to paragraph (c)(3) of this section, each licensee may
   also operate on 12.5 kHz offset frequencies in areas where the licensee
   is authorized on both frequencies adjacent to the offset frequency, and
   in areas where the licensee on the other side of the offset frequency
   consents to the licensee's use of the adjacent offset frequency.
   Coordination with Canada is required for offset operations under any
   circumstance in which operations on either adjoining 25 kHz channel
   would require such coordination. See § 80.57 of this part.

   (2) Any recovered channel pairs will revert automatically to the holder
   of the VPCSA license within which such channels are included, except
   the channel pairs listed in the table in paragraph (c)(1)(i) of this
   section. Those channel pairs, and any channel pairs recovered where
   there is no VPCSA licensee, will be retained by the Commission for
   future licensing.

   (3) VPCSA licensees may not operate on Channel 228B (162.0125 MHz),
   which is available for use in the Coast Guard's Ports and Waterways
   Safety System (PAWSS). In addition, VPCSA licensees may not operate on
   Channel AIS 1 (161.975 MHz) or Channel AIS 2 (162.025 MHz), which are
   designated exclusively for Automatic Identification Systems (AIS),
   except to receive AIS communications to the same extent, and subject to
   the same limitations, as other shore stations participating in AIS. See
   note 3 to the table in paragraph (c)(1) of this section regarding use
   of Channel AIS 1 by VPCSA licensees in VPCSAs 10-42.

   (4) Subject to the requirements of § 1.924 of this chapter and § 80.21,
   each VPCSA licensee may place stations anywhere within its region
   without obtaining prior Commission approval provided:

   (i) It provides to co-channel coast station incumbent licensees, and
   incumbent Private Land Mobile Radio licensees authorized under part 90
   of this chapter on a primary basis, protection as defined in subpart P
   of this part. VPCSA licensees that share a common border may either
   distribute the available frequencies upon mutual agreement or request
   that the Commission assign frequencies along the common border.

   (ii) The locations and/or technical parameters of the transmitters are
   such that individual coordination of the channel assignment(s) with a
   foreign administration, under applicable international agreements and
   rules in this part, is not required.

   (iii) For any construction or alteration that would exceed the
   requirements of § 17.7 of this chapter, licensees must notify the
   appropriate Regional Office of the Federal Aviation Administration (FAA
   Form 7460-1) and file a request for antenna height clearance and
   obstruction marking and lighting specifications (FCC Form 854) with the
   FCC, Attn: Information Processing Branch, 1270 Fairfield Rd.,
   Gettysburg, PA 17325-7245.

   (iv) The transmitters must not have a significant environmental effect
   as defined by § § 1.1301 through 1.1319 of this chapter.

   (d) Working frequencies in the Mississippi River System. The
   Mississippi River System includes the Mississippi River and connecting
   navigable waters other than the Great Lakes. The following simplex
   frequencies are available for assignment to public coast stations
   serving the Mississippi River System for radiotelephony communications.
   These simplex frequencies also are available for use by authorized ship
   stations within communication service range, whether or not the ship is
   operating within the confines of the Mississippi River System.
