§  80.57   Canada/U.S.A. channeling arrangement for VHF maritime public
correspondence.

   (a) Canada/U.S.A. arrangement. Pursuant to arrangements between the
   United States and Canada, assignment of VHF frequencies in the band
   156-162 MHz to public coast stations in certain areas of Washington
   state, the Great Lakes and the east coast of the United States must be
   made in accordance with the provisions of this section.

   (b) Definitions. On the west coast, specific terms are defined as
   follows:

   (1) Inland Waters Public Correspondence Sector. A distinct geographical
   area in which one primary and one supplementary channel is allotted. A
   number of local channels may also be authorized.

   (2) Coastal Waters Public Correspondence Sector. A distinct
   geographical area in which one primary and one supplementary channel is
   allotted. Local channels may also be authorized.

   (3) Inland waters. Inland waters of western Washington and British
   Columbia bounded by 47 degrees latitude on the south, the Canada/U.S.A.
   Coordination Zone Line B on the north, and to the west by 124 degrees
   40 minutes longitude at the west entrance to the Strait of Juan de
   Fuca.

   (4) Coastal waters. Waters along the Pacific Coast of Washington state
   and Vancouver Island within the Canada/U.S.A. Coordination Zone.

   (5) Inland Waters Primary Channel. A channel intended to cover the
   greater portion of an Inland Waters Public Correspondence Sector. It
   may provide some coverage to an adjacent sector but must not provide
   coverage beyond the adjacent sector. Harmful interference beyond the
   adjacent sector must not occur. Only one primary channel will be
   authorized in any sector.

   (6) Inland waters of western Washington and British Columbia bounded by
   46DEG59'59.3" north latitude on the south, the Canada/U.S.A.
   Coordination Zone Line B on the south, and to the west by 124DEG40'4.7"
   west latitude at the west entrance to the Strait of Juan de Fuca.

   Note: All coordinates are referenced to North American Datum 1983
   (NAD83).

   (7) Inland Waters Local Channel. A channel designed to provide local
   coverage of certain bays, inlets and ports where coverage by primary or
   supplementary channels is poor or where heavy traffic loading warrants.
   A local channel must not cause harmful interference to any primary or
   supplementary channels. Coverage must be confined to the designated
   sector.

   (8) Coastal Waters Primary Channel. Same as (5) except for technical
   characteristics.

   (9) Coastal Waters Supplementary Channel. Same as (6) except for
   technical characteristics.

   (10) Coastal Waters Local Channel. Same as (7) except for technical
   characteristics.

   (c) Technical characteristics. On the west coast, technical
   characteristics of public correspondence stations will be as follows:

   (1) Inland Waters Primary and Supplementary Channels. The effective
   radiated power (ERP) must not exceed 60 watts. Antenna height must not
   exceed 152 meters (500 feet) above mean sea level (AMSL) with the
   exceptions noted in paragraph (d)(5) of this section.

   (2) Inland Waters Local Channel. ERP must not exceed 8 watts with an
   antenna height of no more than 15 meters (50 feet) AMSL or the ERP must
   not exceed 2 watts with an antenna height of no more than 30 meters
   (100 feet) AMSL.

   (3) Coastal Waters Primary and Supplementary Channels. ERP must not
   exceed 125 watts with no antenna restrictions.

   (4) Coastal Waters Local Channel. ERP must not exceed 10 watts with a
   maximum antenna height of 76 meters (250 feet) AMSL.

   (5) Harmful interference will be determined and resolved using the
   definition and procedures of the ITU Radio Regulations.

   (6) To keep the ERP and antenna elevations at a minimum and to limit
   coverage to the desired areas, an informal application may be filed for
   special temporary authority in accordance with § § 1.41 and 1.931 of
   this chapter to conduct a field survey to obtain necessary data for
   informal application. Such data may accompany the application and be
   used in lieu of theoretical calculations as required in subpart P of
   this part. The Seattle FCC District Office must be notified in advance
   of scheduled tests.

   (d) Canada/U.S.A. channeling arrangement for West Coast VHF maritime
   mobile public correspondence. (1) The provisions of the Canada/U.S.
   channeling arrangement apply to waters of the State of Washington and
   of the Province of British Columbia within the coordination boundaries
   of "Arrangement A" of the Canada/U.S.A. Frequency Coordination
   Agreement above 30 MHz. In addition, all inland waters as far south as
   Olympia are to be included. A map of these waters is contained in
   paragraph (d)(6) of this section, Figure 1.

   (2) The channeling arrangement applies to the following VHF public
   correspondence channels: Channels 24, 84, 25, 85, 26, 86, 27, 87 and
   28.

   (3) Public correspondence stations may be established by either country
   in accordance with the provisions of the arrangements. However, there
   must be an exchange of information prior to the establishment of new
   stations or a change in technical parameters of existing stations. Any
   channel except that used as primary or supplementary channel in a given
   sector is available for use as a local channel in that sector. Local
   channels are not protected from interference caused by primary or
   supplementary channels in adjacent sectors if these stations are in
   compliance with this section.

   (4) Preliminary local Canadian/U.S. coordination is required for all
   applications at variance with this section. This coordination will be
   in accordance with the provisions of Arrangement "A" of the Canada/U.S.
   Frequency Coordination Agreement over 30 MHz. Stations at variance with
   the arrangement are not protected from interference and must not cause
   interference to existing or future stations which are in accordance
   with the agreement.
