US Coast Guard Frequencies






UNITED STATES COAST GUARD COMMUNICATIONS
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  This frequency list is derived from USCG sources. It should be noted
that certain law enforcement operations utilize "discrete" frequencies,
that are not depicted in any publicly available listings.
When conditions warrant, specific elements of USCG law enforcement
show up on the listed frequencies, employing tactical callsigns and
coded messages.
  Although this listing is the stated usage (for individual freqs),
on a when needed basis, the USCG is at liberty to utilize its HF
frequencies, for whatever purpose they deem necessary.
   The list itself will show in this order the following data:
(1) Frequency, (2) Transmission mode, (3) Xmsm type,
(4) station/usage, (5) Notes.
(1) Frequency - shown are the allocated Carrier freqs. Some freqs may
be shown more than once.
(2) In a single usage mode, the word in parentheses will be used.
Multiple usage will use the single letter codes.
  V (voice) normally USB
  C (CW)
  R (RTTY) - 170 or 850 shift. 2.0 khz above the listed carrier freq.
  F (FAX) - facsimile. 1.9 khz above listed carrier freq.
  P (pulse) - Navigational signals from Omega or Loran-C nets.

(3 Transmission types
  spx - simplex
  dpx - duplex
  both - either spx or dpx when required
  --  - pulse - Omega or Loran-C

(4) Station/Usage - Main USCG Communication facilities are:
NMA - Miami FL      NMO - Honolulu HI
NMC - San Francisco NMR - San Juan, PR
NMF - Boston, MA    NOJ - Kodiak, AK
NMG - New Orleans   NRV - Barrigada, Guam
NMN - Portsmouth, VA
COMMON indicates used by all of the above facilities.
UNITS - any CG cutter or aircraft.

(5) Notes - if applicable will show duplex freq or a numerical
footnote.

Notes to the USCG Communications List:
(1) OMEGA Network....There are eight stations around the world that
transmit pulse type signals, on specific frequencies, and at
precise time lengths and intervals. Omega is used for general purpose
navigation. Since VLF signals travel great distances, it is possible
to receive most of the Omega sites, no matter where you are. For this
purpose, there are special receivers, designed to interpret the
Omega pulses and then display your position (via receiver micro-
processor).
The eight stations are located at:
ALFA    - Bratland, Norway
BRAVO   - Monrovia, Liberia
CHARLIE - Kaneohe, Oahu, Hawaii
DELTA   - La Moure, North Dakota
ECHO    - Reunion Island
FOXTROT - Trewlew, Argentina
GOLF    - Yarram, Australia
HOTEL   - Tsushima Island, Japan

(2) Also can be used by merchant ships. In fact, many of the USCG
frequencies in the 4,6,8,12,13,16,17,22,25, & 26 MHz bands can likewise
be used in communications with merchant vessels.
(3) The IMO (International Maritime Organization) is recommending a
standard worldwide automated broadcast system, to transmit urgent
maritime navigational warnings and notice to mariners.  518 KHz is the
selected frequency, and such a system is now operational in Northern
Europe. The USCG, in late 1983, will run a series of tests to evaluate
the system. Coast Guard COMMSTA Boston will conduct the tests.
(4) Disaster Communications Network - Composed of both government and
non-government radio stations. Has been established to provide
communications, in the event that a major disaster destroys normal
communications facilities. Channel 9 - Scene of disaster only.
(5)  CG District operations involve any shore station or cutter within
the boundries of the district.
(6)  USCG Emergency Command Network.  = This is a point to point
network for communications during emergencies, or for handling
high priority traffic. When Atlantic or Pacific is not mentioned,
frequency is used by both areas.

Atlantic Area Stations:
NMA - Miami, FL                 NMN - Portsmouth, VA
NMF - Boston, MA                NMR - San Juan, PR
NMG - New Orleans, LA           NOZ - Elizabeth City, NC

Pacific Area Stations:
NMC - San Francisco, CA         NOJ - Kodiak, AK
NMO - Honolulu, HI              NRV - Barrigada, Guam
