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.


Check the incoming power for oxidation or loose connections, anything
that causes a voltage drop when the TX load kicks in. Common problem
and easy to overlook.

Hope you are right. I will be checking those danged connections again.


Harry, have you checked the output with an SWR meter? They can be had at radio
shack for about $20. I got one for $5, but it was the last one and it did not
have instructions. You can find info on the internet for their use. Also, my
last radio had a wire broken right next to the hand mike. The break was inside
the insulation so I couldn't see it. I found it accidentally by wiggling the
wire when I had the mike in my hand.

It is really nice having an on topic discussion!!!!!!
