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\

\1\ When R3E, H3E or J3E emission is used, the assigned frequency will
  be 3282.4 kHz (3281.0 kHz carrier frequency).
\2\ This frequency is available only to itinerant stations that have a
  requirement to be periodically transferred to various locations.
\3\ Mobile 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.

   (d)(1) Frequencies in the bands 1435–1525 MHz and 2360–2395 MHz are assigned
   primarily for telemetry and telecommand operations associated with the
   flight testing of aircraft and missiles, or their major components. The
   bands 1525–1535 MHz and 2310–2360 MHz are also available for these purposes
   on a secondary basis. Permissible uses of these bands include telemetry and
   telecommand transmissions 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 1435–1530 MHz, the following
   frequencies are shared with flight telemetry mobile stations: 1444.5,
   1453.5, 1501.5, 1515.5, 1524.5, and 1525.5 MHz. In the band 2360–2390 MHz,
   the following frequencies may be assigned on a co-equal basis for telemetry
   and associated telecommand operations in fully operational or 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 are secondary to the above stated launch vehicle 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.
