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!

This is simple.

The ICOM VHF, model IC-M502 has a microchip that detects certain
speech signals and wave forms. I suspect you were grand-standing about
some political aspect, and the embedded micro chip filter kiced in.

I suspect that some extremest group designed and assembled that radio
to futher enrage the "enlightened". They need to silence you!

If you and your political buddies have an axe to grind, don't waste
valuable time posting here. Reach down deep into you pockets, and if
there are two round things haging, take your soap box and head on down
to your local park/marina (complete with bullhorn & flip charts) and
exercise your freedom of speech to enlighten the masses!

Here's the kicker. Isn't it frustrating that when you want to
discuss/read about boating issues, some jerk posts some political
cr*p, ..... but I know you'll understand. : )

Just a thought.
