  § 87.421   Frequencies.

   The Commission will assign VHF frequencies after coordination with the
   FAA. Frequencies in the following bands are available to control towers
   and RCOs. Channel spacing is 25 kHz.

   118.000-121.400 MHz

   121.600-121.925 MHz

   123.600-128.800 MHz

   132.025-135.975 MHz

   (a) The frequency 123.100 MHz is available for use by control towers
   and RCOs at special aeronautical events on the condition that no
   harmful interference is caused to search and rescue operations in the
   locale involved.

   (b) Frequencies in the bands 200.0-285.0 and 325.0-405.0 kHz will
   normally be assigned only to control towers and RCOs authorized to
   operate on at least one VHF frequency. The Commission may assign
   frequencies in these bands to entities that do not provide VHF service
   in cases where granting such an application will not adversely affect
   life and property in the air.

   (c) Frequencies listed in the introductory paragraph of this section
   are available to control towers and RCOs for communications with ground
   vehicles and aircraft on the ground. The antenna heights shall be
   restricted to the minimum necessary to achieve the required coverage.
   Channel spacing is 25 kHz.

   (d) 121.500 MHz: emergency and distress only.
