[R-390] r390, not the a, audio problem, possibloe agc problem

James,

I had the exact same problem here with one of my
R390's.  But I never determined what the problem was. 
During trouble shooting and alignment I noticed the
problem and put it on the list of things to work on, a
long list for this particular radio.  As time went by,
the problem diminished and finally disappeared all
together.  The only thing I did was keep the radio on
and operating.

Now after 2 years, there is no evidence of the
problem, although I know it is lurking in the
background.  This is a mostly Motorola set and I leave
it on 24/7 as part of my AM station.

Sorry I don't have a solution for you, but I would be
interested in what you find out.  In the mean time,
plug it in and let it play.  Could work for you too.
