Re: VHF Receive but not Transmit?
Back from the boat, and while I didn't have time to try everything, I did apparently fix it. And it does look like corrosion on the antenna connection to the radio was the problem, so thanks KBuckley! The coax connector outside looked fine, but unscrewing and pulling the connector off revealed a layer of corrosion inside, especially up in the pin. A replacement would have been good, but as a spot fix, I hit the area in question with a very small rasp attachment on my cordless Dremel. Screwed the connector back on, connected cable to the radio and was heard loud and clear at a marina down the bay. I'll try some other tests next time, including the auto Seatow radio check, but so far so good.
A new radio might still be in my near future, but I'd rather have it be an option instead of mandatory!
Thanks again everyone.
