I have to ask the question. The man said he was not going to try to fix the
radio himself, that he was going to send it to the service dept, why is
everyone trying to solve the problem? Especially since no one can even look
at the radio.

This ability to solve problems with limited knowledge seems to go beyond
politics to electronics.

I've got that same model and use it quite a bit. The first thing that
occurred to me after reading your post is that possibly the moisture has
seeped in, causing a bad connection somewhere. Another question, did the
problem recur after you tried the antenna on your spare VHF then switched
back to the M502?

I don't think the microphone could be the culprit, since the mic is doing
exactly the same thing at different power transmit levels.

I have an ICOM VHF, model IC-M502, new this past spring, and two
weekends ago, I noticed it was not transmitting properly.

I was "rafting up" with a friend in his boat, and while we were
negotiating the boat hookup, I tried to stay in touch with the VHF. He
could not hear anything at all when I transmitted at the one watt
setting, but could hear me with some signal breakup at the 25 watt
setting. We tried several channels; same results.

It's not the antenna or its fitting, as far as we can tell, because we
hooked up a spare VHF and it did fine.

The friend believes there may be some problem in the M502's mike. My VHF
radio electronics knowledge is minimal. I am going to send the radio
back to ICOM for a look-see and repairs, but I'd like a better
indication from the experts here as to what might be the problem.

Any ideas?

Thanks!
