I don't believe the FCC requires Ham Radio gear to be Type Accepted like the Marine SSB does, since Ham radio operator's often build their own equipment. Bill will correct me if I'm wrong.
I got that from earlier. I'm asking if you can use a marine SSB rig to transmit on the ham nets that the marine ssb rig can pick up, provided you are fully licensed to do so (holding ship station, marine ssb, and proper class level ham license).
If yes, do you use your ham call sign when on the ham bands, but using the marine SSB rig? (that could get confusing)
