Sailing Dog and qc1111,
"If I've read things correctly, if a Ham operator has a station license and a ham license, there is no reason he would not be able to transmit and receive on the marine
SSB frequencies."
Not quite. He/she would be able to RECEIVE on the marine
SSB frequencies, not transmit....at least, not legally. Unless he/she also had a RRO AND a
radio which was type accepted for use on the marine bands.
As has been previously noted, the Icom M-802 apparently is type-accepted for use on both amateur/ham bands and the marine bands, IF you have the proper licenses for both services. A couple of other
rigs are in the same category, but for most people TWO
radios would be needed to LEGALLY transmit on both the ham and the marine
SSB bands.
