Was at the boat the last couple of days and looked at the old 700 SSB I have. Thinking I should replace it with an ICOM 718. Far more user-friendly in the ham bands and I would likely never use the SSB unless an emergency or close. So is the AT 120 compatible or should I just sell the whole thing on e-bay and get an AH 4? Disclaimer: curiosity question... I have spent only a little time researching.
