§ 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
   123.125^2 123.275^3 123.425^3 123.550^3
   123.150^2 123.325^3 123.475^3 123.575^2
   123.250^3 123.350^3 123.525^3

   ^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.

   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) Aeronautical mobile telemetry (AMT) operations are conducted in the
   1435-1525 MHz, 2345-2395 MHz, and 5091-5150 MHz bands on a co-equal basis
   with U.S. Government stations.

   (1) Frequencies in the 1435-1525 MHz and 2360-2395 MHz bands 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. Until January 1, 2020, the 2345-2360 MHz band is also
   available to licensees holding a valid authorization on April 23, 2015 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
   1435-1525 MHz band, the following frequencies are shared on a co-equal basis
   with flight telemetering mobile stations: 1444.5, 1453.5, 1501.5, 1515.5,
   and 1524.5 MHz. In the 2360-2395 MHz band, 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. All other mobile telemetry uses of
   the 2360-2395 MHz band shall be on a non-interfering and unprotected basis
   to the above uses.

   (2) Frequencies in the 5091-5150 MHz band are assigned in the aeronautical
   mobile service on a primary basis for flight testing of aircraft. AMT use of
   these  frequencies  is restricted to aircraft stations transmitting to
   aeronautical stations (AMT ground stations) in the flight test areas listed
   in 47 CFR 2.106, footnote US111.

   (3) The authorized bandwidths for stations that operate in the 1435-1525
   MHz, 2345-2395 MHz, or 5091-5150 MHz bands are normally 1, 3 or 5 MHz.
   Applications for greater bandwidths will be considered in accordance with
   the provisions of § 87.135. Each assignment will be centered on a frequency
   between 1435.5 MHz and 1524.5 MHz, between 2345.5 MHz and 2394.5 MHz, or
   between 5091.5 MHz and 5149.5 MHz, with 1 MHz channel spacing.

   (e) 121.500 MHz: Emergency and distress only.

   (f) Frequency assignments for Flight Test VHF Stations may be based on
   either  8.33 kHz or 25 kHz spacing. Assignable frequencies include the
   interstitial  frequencies  8.33 kHz from the VHF frequencies listed in
   paragraphs (a) and (b) of this section. Each 8.33 kHz interstitial frequency
   is subject to the same eligibility criteria and limitations as the nearest
   frequency listed in paragraphs (a) and (b) of this section.
