Sec.  87.303   Frequencies.

   (a) These frequencies are available for assignment to flight test land and
   aircraft stations:
     kHz       MHz       MHz       MHz
   3281.0^1 123.175^2 123.225^3 123.400^2
            123.200^3 123.375^3 123.450^3

   (b) These additional frequencies are available for assignment only to flight
   test stations of aircraft manufacturers:
      MHz       MHz       MHz        MHz
   123.125^2 123.275^3 S123.425^3 123.550^3
   123.150^2 123.325^3 S123.475^3 123.575^2
   123.250^3 123.350^3 S123.525^3

   ^1When R3E, H3E or J3E emission is used, the assigned frequency will be
   3282.4 kHz (3281.0 kHz carrier frequency).

   ^2This  frequency  is available only to itinerant stations that have a
   requirement to be periodically transferred to various locations.

   ^3Mobile station operations on these frequencies are limited to an area
   within 320 km (200 mi) of an associated flight test land station.

   (c) These frequencies are available for equipment test, emergency and backup
   use with aircraft beyond the range of VHF propagation. Either H2B, J3E, J7B
   or J9W emission may be used.

   3443.0 11288.0

   (d)(1) Frequencies in the bands 1435–1525 MHz and 2360–2395 MHz are assigned
   in the mobile service primarily for aeronautical telemetry and associated
   telecommand operations for flight testing of aircraft and missiles, or their
   major  components.  The bands 2310–2320 MHz and 2345–2360 MHz are also
   available for these purposes on a secondary basis. Permissible uses of these
   bands include telemetry and associated telecommand operations associated
   with the launching and reentry into the Earth's atmosphere, as well as any
   incidental orbiting prior to reentry, of objects undergoing flight tests. In
   the band 1435–1525 MHz, the following frequencies are shared with flight
   telemetry mobile stations: 1444.5, 1453.5, 1501.5, 1515.5, and 1524.5 MHz.
   In the band 2360–2395 MHz, the following frequencies may be assigned for
   telemetry and associated telecommand operations of expendable and re-usable
   launch vehicles, whether or not such operations involve flight testing:
   2364.5, 2370.5 and 2382.5 MHz. In the band 2360–2395 MHz, all other mobile
   telemetry uses shall not cause harmful interference to, or claim protection
   from interference from, the above uses.

   (2)  The  authorized  bandwidths  for  stations operating in the bands
   1435.0–1525.0 MHz, 1525.0–1535.0 MHz and 2310.0–2390.0 MHz are normally 1, 3
   or  5  MHz.  Applications for greater bandwidths will be considered in
   accordance with the provisions of  Sec. 87.135. Each assignment will be centered
   on a frequency between 1435.5 MHz and 1534.5 MHz or between 2310.5 MHz and
   2389.5 MHz, with 1 MHz channel spacing.

   (e) 121.500 MHz: Emergency and distress only.
