New nationwide United States Coast Guard frequencies, as of January 1, 2005, are listed below. The frequencies were changed due to the mandate to vacate 380-400 MHz so that the spectrum could be used for military trunked radio systems.

HF Operations
The US Coast Guard uses 4 different types of mechanisms for HF Radio Communications.
The first method is the use of the Dept of Homeland Security HF COTHEN ALE Network. This network supports most normal flight operations and flight following for US Coast Guard aircraft and helos and is the primary HF communications method for USCG assets.
The second method is the use of a backup USCG HF Radio network that primarly supports aircraft and helos that do not have ALE capable HF radios. The following frequencies are typically used:
5696 8983 11201
Third, the USCG uses a set of HF frequencies for tactical radio communications between aircraft, base stations, and USCG Cutters
5320.0 8337.6 10993.6 11197.4 (Mobile AL)
And finally, the USCG has a network called TISCOM which operates on the following frequencies:
3053 4730 6709 8057 8859 8980 9034 11196 13221 15082 17988 20135.5 23072.5

USCG Auxiliary
The USCG has moved to Narrowband channels and abandoned the older wideband channels.
150.7000 is the Repeater with 149.2000 as the input.
Other Simplex channels are:
138.4750 TAC-1
142.8250 TAC-2
143.4750 Nationwide Simplex
