And yeah you could say it is "old technology", but that particular radio has a few modern bells and whistles. Much more useful than a "plain" SSB. If you read the manual and learn a bit about what it can do, you might decide you would just as soon keep it.
IF NOTHING ELSE, it makes a dandy SW receiver. Good for NAVTEX and WEFAX. Good for marine
nets and for HAM use if you decide to get into that. And not knocking the sat phone
, but in an emergency
your radio and its distress
call function gets the message out immediately to vessels similarly equipped within hundreds of miles. With satellite
you can comminicate with only one party at a time. With radio, anybody can break in and offer assistance. Anybody can monitor
your situation without going throuch a third party. The two, HF and satellite, are not mutually exclusive. They complement each other. You can certainly go to sea with just one or the other, but why not both, since the radio is already installed?
There are of course haters out there, for some reason, who would tell you to just pitch
the useless pile of crap overboard
. But it is far from useless.
If you are in the US, you will want to get a ship station license
. Dealing with the FCC can be er, "challenging" but find yourself an "Elmer" to guide you through the licensing process and it will soon be over and done with, and you will be legal
BTW, FWIW air time is free.
There is at least one good book on Amazon specifically on how to set up and use your M802. Get it. You won't regret it.
