What are the marine SSB frequencies?
What are the marine SSB frequencies?
A marine SSB system operates on marine radio spectrums called shortwave, medium frequency and high frequency — 2 MHz-26 MHz. This radio spectrum is shared with hundreds of other radio users including shortwave broadcasts, Ham radio, FEMA, the American Red Cross, and long-range aircraft.
What marine VHF channels can I use?
What channels should you use for regular conversations? Channels 68, 69, 71, 72, and 78A are considered non-commercial channels, and in most areas, 68 and 72 are commonly used by the recreational-boating community. But remember that the VHF is officially for “operational” purposes.
What channels are on a marine radio?
What are marine VHF channels used for?
- Ch 16 is the Distress, Safety and Calling channel.
- Ch6, Ch8, Ch72 and Ch77 are designated intership channels.
- Ch67 is the small ships safety channel.
- Ch70 is the DSC channel.
- Ch80 is the normal channel for UK marinas.
What is the emergency channel on VHF?
VHF maritime channel 70 (156.525 MHz) is authorized exclusively for distress, safety and calling purposes using digital selective calling (DSC) techniques. No other uses are permitted.
What is channel 16 on a marine radio?
Channel 16 is designated as the national distress, safety and calling frequency. All vessels should monitor this channel while underway. When hailing other boats for routine communication, you’ll need to hail them on 16 or 09, and then move to an available working channel, usually 68, 69, 71 or 72.
What are SSB channels?
CB service operates on 40 shared channels in an AM mode or Single SideBand (SSB) mode. SSB offers less noise and greater range than AM mode and is usually found on higher end CB radios. SSB has two modes, Upper Sideband and Lower Sideband.
What radio channel is VHF?
channel 16
Tune to channel 16, the channel monitored by the U.S. Coast Guard. Perform a radio check to ensure your unit is functioning properly—do not use channel 16 this. Use an “open channel” to performance the check (channels 68, 69, 71, 72 and 78A).

Where can I find SSB simplex radio frequencies?
Government shore, ship and aircraft stations for search and rescue coordination. These 2 MHz SSB simplex radiotelephone frequencies are available for ships in or near U.S. waters.
How does a Marine MF / HF radio work?
Unlike VHF which is typically a line of sight radio, MF/HF radios are able to refract their signals within the atmosphere providing increased range. This plays an important role in long distance ship to ship or ship to shore communications.
