SSB Radio

Known as SSB (single sideband) radios in the sailing community, these radios provide both voice and data communications over thousands of miles utilizing HF, or high frequency, and MF, or medium frequency, spectrum. Marine MF/HF radios, when properly configured with a MMSI, are a part of the GMDSS utilizing DSC.

Unlike Amateur Radio, marine MF/HF radios use specific channels for communicating - similar to the marine VHF radio. Some channels are specifically designated for distress and safety calling while others can be used to contact commercial shore stations that provide telephone and data connectivity. Prior to transmitting on a channel it is important to understand the purpose of the channel to avoid interfering with other communications.

Other services found on marine HF and MF frequencies are weather broadcasts directly from government sources in the form of voice, SITOR, and facsimile formats. These broadcasts can be received with a simple shortwave receiver and, in the case of SITOR and facsimile, a computer with a sound card.

Many sailors keep in contact with each other and shore stations by the use of nets. These nets are simply a time of day when operators will monitor a certain frequency to hear if there is anyone trying to make contact with them. Nets may also pass weather information and can be useful for asking specific questions of conditions in certain locations.

Licensing

Operation of a HF/MF marine radio requires a license. This license allows you to not only transmit your HF/MF radio in your country's home waters but also in international waters and waters of other countries.
