The USCG are heavy users of the Marine VHF band; Channel 16 is reserved for distress, safety and calling, while channel 22A is utilized for special warnings, Marine Safety and other announcements. Other frequencies utilized vary from sector to sector.

Air Operations

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.

345.0   Operations Primary       AM Mode
237.9   Operations Secondary     AM Mode
326.15  Air-to-Ground Primary    AM Mode
379.05  Air-to-Ground Secondary  AM Mode

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.

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

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
