  §  90.715   Frequencies available.

   (a) The following table indicates the channel designations of
   frequencies available for assignment to eligible applicants under this
   subpart. Frequencies shall be assigned in pairs, with base station
   frequencies taken from the 220-221 MHz band with corresponding mobile
   and control station frequencies being 1 MHz higher and taken from the
   221-222 MHz band. Only the lower half of the frequency pair(s) is
   listed in the table. Use of these frequencies in the Mexican and
   Canadian border areas is subject to coordination with those countries.
   See paragraph (c) of this section for special provisions concerning use
   in the Mexico border area.

   (b) The 200 channels are divided into three sub-bands as follows:
   Channel No. Sub-band          Frequencies (MHz)
      1-40     A        220.0025-220.1975/221.0025-221.1975
     41-160    C        220.2025-220.7975/221.2025-221.7975
   161-200     B        220.8025-220.9975/221.8025-221.9975

   (c) U.S./Mexico border area. (1) Channels 16-30, 45-60, 76-90, 106-120,
   136-145, 156-165, 178-194 are available for primary use within the
   United States within 120 km (74.6 mi) of the Mexican border, subject to
   the power and antenna height conditions specified in § 90.729 and the
   use restrictions specified in § § 90.717-90.721.

   (2) Channels 195-200 are available to both the United States and Mexico
   in the border area on an unprotected basis. Use is limited to a maximum
   effective radiated power (ERP) of 2 watts and a maximum antenna height
   of 6.1 meters (20 ft) above ground.

   (3) Channels allotted for primary Mexican use (1-15, 31-45, 61-75,
   91-105, 121-135, 146-155, and 166-177) may be used in the border area
   subject to the condition that the power flux density not exceed−86
   dB(W/m2) at or beyond any point on the border. Stations operating under
   this provision will be considered secondary and will not be granted
   protection from harmful interference from stations that have primary
