§ 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.

(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.
