§ 73.504   Channel assignments in the Mexican border area.

   (a) NCE-FM stations within 199 miles (320 km) of the United States-Mexican
   border shall comply with the separation requirements and other provisions of
   the “Agreement between the United States of America and the United Mexican
   States Concerning Frequency Modulation Broadcasting in the 88 to 108 MHz
   Band” as amended.

   (b) Applicants for noncommercial educational FM stations within 199 miles
   (320 km) of the United States-Mexican border shall propose at least Class A
   minimum facilities (see § 73.211(a)). However, existing Class D noncommercial
   educational stations may apply to change frequency within the educational
   portion of the FM band in accordance with the requirements set forth in
   § 73.512.

   (c)  Section  73.208  of this chapter shall be complied with as to the
   determination  of  reference  points and distance computations used in
   applications for new or changed facilities. However, if it is necessary to
   consider a Mexican channel assignment or authorization, the computation of
   distance will be determined as follows: if a transmitter site has been
   established, on the basis of the coordinates of the site; if a transmitter
   site has not been established, on the basis of the reference coordinates of
   the community, town, or city.
