2671.4(2670) 157.1 MHz
Note: The carrier frequency 2670 kHz and 157.1 MHz are designated as
the Coast Guard and NON-Government (NG) ship stations liaison
frequencies. They are available for use by ship stations to communicate
with the Coast Guard and to receive marine information and certain
weather broadcast information. Policy for public use is:
1. The Coast Guard encourages NG MF and VHF-FM equipped ship
stations to install these frequencies for communications
with the Coast Guard only. In accordance with FCC Rules,
2670 kHz and 157.1 MHz are available to ship stations when
authorized by their station license. Concurrence from the
Coast Guard is not required.
2. The District Commanders may issue a letter of concurrence to
support applications to the FCC for use of these
frequencies by NG coast stations to communicate with Coast
Guard mobile units, when the NG coast station belongs to a
government organization whose operations are closely allied
to operations of the Coast Guard and, in the judgement of
the District Commander, whose suport is frequently
necessary to more effectively carry out Coast Guard
missions. When an agreement for NG coast station use is
given it is subject to the following conditions which
should be included in the letter of concurrence:
a. Use shall by limited to communications with the Coast
guard on matters related to safety and emergencies.
b. Use will be on a not-to-interfere basis with Coast
Guard usage of the frequency.
c. Usage authorization is on a temporary basis for a
period no longer than 5 years.
d. Temporary periods are renewable and require a new
letter of concurrence from the District Commander.
e. Letters of concurrence are issued subject to acceptance
by licensee of the condition that use of this frequency
will be immediately terminated on request of the Coast
Guard operationsr require such action.
f. The Coast Guard will not support any use of 2670 kHz
and/or 157.1 MHz for communications between two
NON-Coast Guard users. Whenever a District Commander
authorizes a NG coast station use of 2670 kHz or 157.1
MHz he will forward a copy of the letter of concurrence
to Commandant (G-TTM).
