Ham radio is the realm of a world-wide group of radio enthusiasts. Operators have been involved in many life saving efforts with sailors, but regrettably radio operators and the system have been badly abused by some yachtsmen. The Ham Radio is a major communication source in the cruising world.
In the US, about 70% of cruisers sail with ham, while UK and Australia it is probably around 10%. There are a number of important factors to consider with respect to ham radio operation.
It is the operator not the station that is licensed. There are a number of levels that give either partial or full access to frequencies.
Levels require examination in Morse, radio theory, rules and regulations with respect to operations. It is this fear of technical matters and theory as well as the Morse that frightens many would be amateurs.
A ham radio general class license will be required for access to Maritime Mobile Nets in the 15, 20 and 40 metre bands.
You must be licensed for the country of operation, and beware in some third world countries were communications are controlled, jail and vessel loss can occur if it is used in port and without authorisation. In many cases you will not be acknowledged on ham radio bands unless you are licensed and have a call sign.
This argument is never ending. Both systems have a place, well actually SSB is virtually gone so argument is essentially over. In an ideal world carry both systems. SSB Radio sets are generally easier to operate for non technical people, and with automatic tuning it is simple to punch in a channel number and talk. Additionally radios have automatic emergency channel selection.
Radios are also type approved for marine communications. Only a Restricted Radio Telephone Operators Permit is required. It is allowable to operate a SSB radio on amateur frequencies if you have a ham radio licence. One of the disadvantages of SSB on ham radio frequencies is that synthesizers are programmed in 0.10kHz steps. As is often the case, ham communications may be at frequencies outside of that so that SSB sets can be marginally off frequency.
Most SSB sets operate on Upper Side band (USB) while most ham frequencies below 40 metres are Lower Side Band (LSB). The ham operator must have a license appropriate to the frequency band being worked. Access to GMDSS emergency frequencies is illegal except in emergencies. It is illegal to operate non type approved radios such as ham radios on marine frequencies. Ham allows the use of casual conversation and chit-chat which marine SSB does not. Ham allows full access to information packed nets, and a worldwide communications network. Ham radio does not readily allow access to telephone networks, although some stations offer phone patches.
This is a very good and useful selection of Ham Radio Nets extracted from the listings in the Marine Electrical & Electronics Bible. If you are not a licensed operator, invest in a receiver only and listen in to the nets, the information can be invaluable. I cannot vouch for the accuracy of these nets and trying to research and update them as regularly as possible.
