HF, or high frequency, radios provide communication beyond the range of the traditional VHF radio that many mariners rely on in coastal waters. VHF radios are typically limited to near 30 miles of range while HF radios can cover thousands of miles. There are generally two ways to take advantage of the HF spectrum while at sea: Marine Radio and Amateur Radio. Both have benefits and drawbacks. It should be noted that while we identify these radios as HF they typically include MF or medium frequency coverage as well. MF frequencies are especially important in the marine bands as they are the primary means of communicating with shore emergency services, such as the Coast Guard, when operating within 250 miles of the shore, in accordance with GMDSS.
Marine HF radio is also called SSB in some sailing circles. SSB, however, identifies the modulation of the transmission and not the actual frequencies used. This would be akin to calling your VHF radio your FM radio.
