Why marine SSB
Worldwide Communications via HF radio

Marine SSB (Single Side Band) is a popular means of communications for the independent cruising yachtsmen and a must if you are planning to do bluewater cruising to the Caribbean, Pacific or Mediterranean.
The range of SSB is up to several thousand miles and calls between yachts are free and there are coast stations broadcasting weather bulletins and even low cost SSB email.
The marine SSB transceivers (Icom M801E or M802 have digital selective calling (DSC) which allows you to send and receive distress, urgency and safety communications between other ships and to and from coastguard. SSB DSC can also be used for routine calling between yachts.

Having an SSB MF/HF transceiver on board your yacht offers communication independence, you are not tied into any contracts or connection charges.
You just require a ships radio licence and a marine radio long range operator's certificate


Marine HF radio

High Frequency (HF) radio works on frequencies between 3 MHz to 30 MHz which lies between medium-wave (MF) and VHF radio. HF radio waves can refract (bend) of the ionosphere giving coverage over hundreds or even thousands of miles and therefore ideal for long distance communications.
Icom M801E
Marine SSB (Single Side Band) or HF (High Frequency) is a popular means of communication for the independent cruising yachtsmen and a must if you are planning to do bluewater cruising to the Caribbean, Pacific or Mediterranean.

The range of SSB is upto several thousand miles and calls between yachts are free.
In most parts of the world you can communicate with the coastguard up to several hundred miles off-shore.

Global weather can be received via fax and data and you can send and receive email.
Having an SSB transceiver on board offers security, entertainment and general communications while at sea.

If you want the capability of being able to transmit on all marine frequencies which include MF/HF/VHF and Inmarsat satellite from a yacht then you need a GMDSS Long Range Certificate (GMDSS LRC)

HF radio propagation

Low frequencies follow the curvature of the earth and this type of propagation is called Ground Wave, while higher frequency radio wave can also refract off the Ionosphere this type of propagation is called Sky Wave. On higher frequencies where Sky Wave propagation dead zones (where no signal is received) may occur when close to a transmitting station.

A good rule for daytime is 100 miles per MHz:-
MF/HF Range Freq. Day-light Darkness
2 MHz 200 NM 500NM
4 MHz 400 NM 800NM
6 MHz 600 MN 1200 NM
8 MHz 800 NM 1600NM
12 MHz 1200NM 2400NM
16 MHz 1600 NM fade-out
