                     Subpart J--Flight Test Stations
 
Sec. 87.303  Frequencies.

    (a) These frequencies are available for assignment to flight test 
land and aircraft stations:

    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:

   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.
    Frequencies (carrier) available kHz:

                                   kHz
2851.0                               8822.0
3004.0                               10045.0
3443.0                               11288.0
5451.0                               11306.0
5469.0                               13312.0
5571.0                               17964.0
6550.0                               21931.0


    (d)(1) Frequencies in the bands 1435-1525 MHz and 2360-2390 MHz are 
assigned primarily for telemetry and telecommand operations associated 
with the flight testing of manned or unmanned aircraft and missiles, or 
their major components. The band 1525-1535 MHz is also available for 
these purposes on a secondary basis. In the band 2320-2345 MHz, the 
mobile and radiolocation services are allocated on a primary basis until 
a Broadcast-Satellite (sound) service has been brought into use in such 
a manner as to affect or be affected by the mobile and radiolocation 
services in those service areas. 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 manned or unmanned objects undergoing 
flight tests. In the 1435-1530 MHz band, 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 2320-2345 MHz and 2360-2390 MHz 
bands, 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: 2332.5, 2364.5, 2370.5 and 2382.5 MHz. In the 
2360-2390 MHz band, all other telemetry and telecommand 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.
