I do sometimes question what all the regulations are about worldwide.
The idiots of the world without registration or licencing are going to try to talk to fighter pilots or Jumbo jet pilots.
Its just that Icom seem to dominate the market place for marine hf despite the fact that it was probably a Yaesu hf radio that confirmed the sucessful raid on Pearl Harbour!
Sorry but I smell monopolistic practises.
Otherwise why did Yaesu in its early FT 757 make it so easy with a slide swtich to open up the radio? Or in later models jump leads and latterly a simple programme adjustment accessed through the programmimg sequences?
Was it hoping to have its ham radios authorised for marine use.
Likewise its Vertex open chanel tranceivers.
When here in the UK you have to pay 30% more for a marine legal Icom HF than in the US restrictive trading practises at least come to mind.
