Agreed but you could have a bad connection which is heating up under
load.



BINGO! They use one of those crap, 'slow burn' fuses. They heat up and
the
extra impedance reduces the voltage. Get rid of it and put a higher
amperage
rated, fast burn fuse in - end of problem.

Bull****.... Wilbur, you need to stick to stuff you know about....
as Peter Bennett pointed out, if the volume at the receiver dropped, but
the background noise didn't change, then the problem is in the
Modulating Deviation, not the Power Output.... This is FM not AM or
SSB.... In FM, once you exceed 12 db of Receiver Quieting the
Background Noise, changes are hardly perceptible, and in FM, the volume
produced in the receiver is directly proportional to the Modulation
Deviation of the Transmitter, until it exceeds the bandwidth of the
Receiver.

You don't read too well, dude. Skippy said the volume of his 'transmission'
as heard by other listeners in nearby boats decreased noticeably after about
a minute.

So the problem is with Skippy's transmitter and not his receiver. If the
fuse heats up and the voltage drops and the "low voltage" indicator flashes
in the readout as Skippy indicated then that should tell you something. Duh!
