I have not reviewed the regulations
regarding marine radio
for a long time however I don't think it would have changed much.
For marine VHF
and HF you were required to have a ship station operators license and the ship station was also required to be registered for which there was an annual fee.
However since the volunteer rescue
organizations started and spread VHF
on small vessels has become ubiquitous and I suspect that the majority of them are not registered facilities. HF SSB
is not as common however many cruising yachts have it to listen to the dedicated Bureau Of Meteorology SSB
transmissions and there are a couple of yachting networks on SSB.
is one of those places which has lots of laws about many things however provided transgressions are not harming other peoples interests or infringing their rights the transgressions are tolerated and I suspect this is the situation in regard to VHF usage. All these folks are not complying with the registration
or licencing requirements but for safety
purposes it is better that they have the VHF radios so the transgressions are tolerated.
Australia used to have a network of government
operated coastal radio stations dedicated to commercial
traffic on both VHF and HF SSB but just about all of these closed down years ago, as commercial
operators fitted satellite
systems to their vessels they fell into disuse.
I occasionally scan across the marine channels on my SSB but about the only thing you hear is Asians having a chat. When I worked in the boondocks in Indonesia
quiet a lot of the locals had ham transceivers they used to call home every day and you still hear the occasional one on marine frequencies.
My son has a ham license and I have suggested that we go duplex with him transmitting on a ham frequency and I on marine and his answer was "cross channel work is verboten", pedantic little rat. Consequently I suspect you are more likely to run into problems with illicit use of ham frequencies than marine.
I have been told by radio service
professionals that marine rated transceivers are more durable in the marine environment
because the electronics
are better protected from corrosion
