§ 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 are based on 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:

(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 25
kHz channel spacing. Proposed operations must be compatible with
existing operations in the band.
