The factory installed Icom M422 VHF quit working. It worked fine the last time I sailed but today- no such luck. The weather channels work fine and I get static on the others when I turn the squelch down but no audio. The display indicates TX when I key the mike but no response to radio checks. I did lower and raise the furling headsail which has an internal mast halyard but I think the wiring (antenna lead) is in a protective conduit.
Does this sound like an antenna problem or radio malfunction and how do I test the antenna at the mast base without climbing to the top?
