  §  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.

   (4) Frequencies in the bands 1435-1525 MHz are also available for low
   power auxiliary station use on a secondary basis.

   (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.
