§ 87.263 Frequencies.
(a) Domestic VHF service. (1) Frequencies in the 128.8125-132.125 MHz and
136.4875-137.00 MHz bands are available to serve domestic routes, except
that the frequency 136.750 MHz is available only to aeronautical enroute
stations located at least 288 kilometers (180 miles) from the Gulf of Mexico
shoreline (outside the Gulf of Mexico region). The frequencies 136.900 MHz,
136.925 MHz, 136.950 MHz and 136.975 MHz are available to serve domestic and
international routes. Frequency assignments may be based on either 8.33 kHz
or 25 kHz spacing. Use of these frequencies must be compatible with existing
operations and must be in accordance with pertinent international treaties
and agreements.
(2) A system or network of interconnected enroute stations may employ offset
carrier techniques on the frequencies listed in paragraph (a)(1). The
carrier frequencies of the individual transmitters must not be offset by
more than ±8kHz.
(3) The frequencies 122.825 and 122.875 MHz are available for assignment to
enroute stations which provide local area service to aircraft approaching or
departing a particular airport. These frequencies will be assigned without
regard to the restrictions contained in § 87.261 (c) and (d). Only
organizations operating aircraft with a maximum capacity of 56 passengers or
8,200 kg (18,000 lbs) cargo will be authorized use of these enroute
frequencies.
(4) In Alaska, the frequencies 131.500, 131.600, 131.800 and 131.900 MHz may
be assigned to aeronautical enroute stations without regard to the
restrictions contained in § 87.261 (c) and (d).
(5) The frequency 136.750 MHz is available in the Gulf of Mexico Region to
serve domestic routes over the Gulf of Mexico and adjacent coastal areas.
Assignment of this frequency in the Gulf of Mexico Region shall be to
licensees first licensed on this frequency in the Gulf of Mexico Region
prior to January 1, 1994, their successors and assigns, and is not subject
to the conditions in § 87.261(c) and paragraph (a)(2) of this section. For
the purpose of this paragraph, the Gulf of Mexico Region is defined as an
area bounded on the east, north, and west by a line 288 km (180 miles) from
the Gulf of Mexico shore line. Inland stations must be located within
forty-eight kilometers (30 miles) of the Gulf of Mexico shore line.
(b) Domestic HF service. (1) Regular use of high frequencies for
aeronautical enroute or any aeronautical mobile (R) communications in the
domestic service within the continental United States (excluding Alaska)
will not be authorized.
(2) These frequencies (carrier) are available for assignment to serve
aircraft operating in support of offshore drilling operations in open sea
areas beyond the range of VHF propagation:

to serve domestic air routes in the Alaska area:
(i) Throughout Alaska: Shared with the FAA and assigned where an applicant
shows the need for a service not provided by the FAA.
kHz
2866.0 5631.0
(ii) Alaska Aleutian chain and feeders.

(iv) The following frequencies (carrier) are available to enroute stations
in Alaska without regard to the restrictions contained in § 87.261 (c) or
(d). These frequencies may also be used for communications between enroute
stations concerning matters directly affecting aircraft with which they are
engaged. Enroute stations located at an uncontrolled airport shall not
transmit information concerning runway, wind or weather conditions during
the operating hours of a unicom.
kHz
3449.0 5472.0
5167.5^1 5490.0
^1The frequency 5167.5 kHz is available to any station for emergency
communications in Alaska. No airborne operations are permitted. Peak
envelope power of stations operating on this frequency must not exceed 150
watts. This frequency may also be used by Alaska private fixed stations for
calling purposes, but only for establishing communications.
(c) International VHF service. Frequencies in the 128.825-132.000 and
136.000-137.000 MHz bands are available to enroute stations serving
international flight operations. Frequency assignments are based on either
8.33 kHz or 25 kHz channel spacing. Proposed operations must be compatible
with existing operations in the band.
(d) International HF service. High frequencies (carrier) available to
enroute stations serving international flight operations on the Major World
