[R-390] Broadcast Band On Other Bands

[Scott, Barry (Clyde B)]

Mine does the same thing.  It's almost like it gets a sudden 10dB gain.  Is yours a '56 Motorola?  I wonder if it's manufacturer/contract specific.

Mike,

This makes me think of several things. First, I sometimes get a sudden pop
of louder audio especially if I've had the radio parked on a frequency for a
long time. Something seems to open up somewhere for full audio. It has been
going on for a few years now. Turning up the RF Gain usually gives me full
audio again, or turning the MC Change knob up or down a band will do it. I'm
pretty sure that the racks are moving loose enough to not bind like they do
on my other one. Sometimes I get the impression that crud on the Local Gain
and RF Gain pots is causing the problem.

Maybe some of these stations are harmonics?



Barry
