MMSI registration and DSC
I got a really cool handheld VHF for Christmas (an HX850S, IIRC). It has DSC features. I was going to take the advice in the manual and register for a free MMSI from BoatUS, but after reading up on it a bit, I wonder if that's a good idea. It seems these free MMSIs aren't any good in foreign waters. I currently have no plans to go to foreign waters, but I imagine in the not too distant future I will want to go to Canada, Bermuda, or the Bahamas. The licenses seem to cost $160. Should I just bite the bullet now and get an FCC MMSI?
It also seems that they're attached to a particular boat, so if I buy a new boat I need to do it again (and get a new MMSI for the new boat), is that correct? If so, perhaps I should just go with the free one, since I don't know if I'll hang on to this boat long enough to go anywhere other than Canada, and it seems the rules aren't enforced there, and are in the process of being lifted.
Lastly, this is a handheld radio and I fully expect to use it on other people's boats. Is that a problem? I can't very well reprogram the MMSI every time I go out on someone else's boat. How should this situation be handled?
