§ 1.928   Frequency coordination, Canada.

   (a) As a result of mutual agreements, the Commission has, since May 1950 had
   an  arrangement with the Canadian Department of Communications for the
   exchange of frequency assignment information and engineering comments on
   proposed assignments along the Canada-United States borders in certain bands
   above 30 MHz. Except as provided in paragraph (b) of this section, this
   arrangement involves assignments in the following frequency bands.

MHz

   30.56-32.00    75.40-76.00
   33.00-34.00    150.80-174.00
   35.00-36.00    450-470
   37.00-38.00    806.00-960.00
   39.00-40.00    1850.0-2200.0
   42.00-46.00    2450.0-2690.0
   47.00-49.60    3700.0-4200.0
   72.00-73.00    5925.0-7125.0

GHz

   10.55-10.68    10.70-13.25

   (b) The following frequencies are not involved in this arrangement because
   of the nature of the services:

MHz

   156.3     156.95
   156.35    157.0 and 161.6
   156.4     157.05
   156.45    157.1
   156.5     157.15
   156.55    157.20
   156.6     157.25
   156.65    157.30
   156.7     157.35
   156.8     157.40.
   156.9 

   (c) Assignments proposed in accordance with the railroad industry radio
   frequency allotment plan along the United States-Canada borders utilized by
   the Federal Communications Commission and the Department of Transport,
   respectively, may be excepted from this arrangement at the discretion of the
   referring agency.

   (d) Assignments proposed in any radio service in frequency bands below 470
   MHz appropriate to this arrangement, other than those for stations in the
   Domestic Public (land mobile or fixed) category, may be excepted from this
   arrangement at the discretion of the referring agency if a base station
   assignment has been made previously under the terms of this arrangement or
   prior to its adoption in the same radio service and on the same frequency
   and  in  the local area, and provided the basic characteristics of the
   additional station are sufficiently similar technically to the original
   assignment to preclude harmful interference to existing stations across the
   border.

   (e) For bands below 470 MHz, the areas which are involved lie between Lines
   A and B and between Lines C and D, which are described as follows:

   Line  A—Begins  at Aberdeen, Wash., running by great circle arc to the
   intersection of 48 deg. N., 120 deg. W., thence along parallel 48 deg. N.,
   to the intersection of 95 deg. W., thence by great circle arc through the
   southernmost point of Duluth, Minn., thence by great circle arc to 45 deg.
   N.,  85  deg.  W.,  thence southward along meridian 85 deg. W., to its
   intersection with parallel 41 deg. N., thence along parallel 41 deg. N., to
   its  intersection with meridian 82 deg. W., thence by great circle arc
   through the southernmost point of Bangor, Maine, thence by great circle arc
   through the southern-most point of Searsport, Maine, at which point it
   terminates; and

   Line  B—Begins  at  Tofino,  B.C.,  running by great circle arc to the
   intersection of 50 deg. N., 125 deg. W., thence along parallel 50 deg. N.,
   to  the  intersection of 90 deg. W., thence by great circle arc to the
   intersection of 45 deg. N., 79 deg. 30′ W., thence by great circle arc
   through the northernmost point of Drummondville, Quebec (lat: 45 deg. 52′
   N., long: 72 deg. 30′ W.), thence by great circle arc to 48 deg. 30′ N., 70
   deg.  W., thence by great circle arc through the northernmost point of
   Campbellton, N.B., thence by great circle arc through the northernmost point
   of Liverpool, N.S., at which point it terminates.

   Line C—Begins at the intersection of 70 deg. N., 144 deg. W., thence by
   great circle arc to the intersection of 60 deg. N., 143 deg. W., thence by
   great circle arc so as to include all of the Alaskan Panhandle; and

   Line D—Begins at the intersection of 70 deg. N., 138 deg. W., thence by
   great  circle  arc to the intersection of 61 deg. 20′ N., 139 deg. W.,
   (Burwash Landing), thence by great circle arc to the intersection of 60 deg.
   45′ N., 135 deg. W., thence by great circle arc to the intersection of 56
   deg. N., 128 deg. W., thence south along 128 deg. meridian to Lat. 55 deg.
   N., thence by great circle arc to the intersection of 54 deg. N., 130 deg.
   W., thence by great circle arc to Port Clements, thence to the Pacific Ocean
   where it ends.

   (f) For all stations using bands between 470 MHz and 1000 MHz; and for any
   station of a terrestrial service using a band above 1000 MHz, the areas
   which are involved are as follows:

   (1) For a station the antenna of which looks within the 200 deg. sector
   toward the Canada-United States borders, that area in each country within 35
   miles of the borders;

   (2) For a station the antenna of which looks within the 160 deg. sector away
   from the Canada-United States borders, that area in each country within 5
   miles of the borders; and

   (3) The area in either country within coordination distance as described in
   Recommendation 1A of the Final Acts of the EARC, Geneva, 1963 of a receiving
   earth station in the other country which uses the same band.

   (g)  Proposed assignments in the space radiocommunication services and
   proposed assignments to stations in frequency bands allocated coequally to
   space  and  terrestrial  services above 1 GHz are not treated by these
   arrangements.  Such proposed assignments are subject to the regulatory
   provisions of the International Radio Regulations.

   (h) Assignments proposed in the frequency band 806-890 MHz shall be in
   accordance with the Canada-United States agreement, dated April 7, 1982.
