Sec.  73.507   Minimum distance separations between stations.

   (a) Minimum distance separations. No application for a new station, or
   change in channel or transmitter site or increase in facilities of an
   existing station, will be granted unless the proposed facilities will be
   located so as to meet the adjacent channel distance separations specified in
    Sec. 73.207(a) for the class of station involved with respect to assignment on
   Channels 221, 222, and 223 listed in  Sec. 73.201 (except where in the case of an
   existing station the proposed facilities fall within the provisions of
    Sec. 73.207(b)), or where a Class D station is changing frequency to comply with
   the requirements of  Sec. 73.512.

   (b) Stations authorized as of September 10, 1962, which do not meet the
   requirements of paragraph (a) of this section and  Sec. 73.511, may continue to
   operate as authorized; but any application to change facilities will be
   subject to the provisions of this section.

   (c)(1) Stations separated in frequency by 10.6 or 10.8 MHz (53 or 54
   channels) from allotments or assignments on non-reserved channels will not
   be authorized unless they conform to the separations in Table A given in
    Sec. 73.207.

   (2) Under the United States-Mexican FM Broadcasting Agreement, for stations
   and assignments differing in frequency by 10.6 to 10.8 MHz (53 or 54
   channels), U.S. noncommercial educational FM allotments and assignments must
   meet the separations given in Table C of  Sec. 73.207 to Mexican allotments or
   assignments in the border area.
