===Description===
 
-
Marine radio or 'maritime mobile' is the most effective means of communication at sea - HAM HF (amateur radio) and SSB marine frequencies is used for long range, and VHF for contact up to about 20 miles. Marine radio nets are set up by controllers all over the world (Indian Ocean, Atlantic, Mediterranean, Pacific, etc.) to handle and co-ordinate this traffic from vessels sailing the oceans. It is important for cruising yachts to know these radio net frequencies and times so as to pass message traffic, log positions, receive weather information, etc

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 [[Ham_Radio|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 [https://secure.wikimedia.org/wikipedia/en/wiki/Global_Maritime_Distress_Safety_System GMDSS].

===Forum Discussions===

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.

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.

Because HF communications are a bit less straight forward than VHF communications links below are provided to help break down the topic a bit.

Basic Radio Procedures

See Radio Calling Procedure. This applies to routine and distress calls for both HF Radio and VHF Radio, any differences are noted.

Equipment Check

  • Is the correct frequency/channel selected?
  • Is the volume adjusted correctly?
  • Is the squelch adjusted correctly?
  • Is the RF gain set to maximum sensitivity?
  • Power supply - is the battery fully charged?
  • Antenna - are the leads and whip intact, not corroded, have proper earthing and connections in good order?
  • Listen before transmitting to ensure you have a clear channel
