Well... it could be many things in the audio chain. Probably the most
likely is the audio output device. Not sure exactly what that is in
your rig... but most take the form of a IC that is normally attached to
the aluminum chassis to sink the heat away.

I'm using the stock uniden mike. It's a dynamic microphone. I put it on
my Cobra, and listened to the audio quality, and it was fine. I haven't
had luck getting my cobra mic working on this uniden however , but
the audio quality is the same with both mic's. I took it apart, and I'm
not sure if someone fiddled with it, a wire was twisted together, but
poking around didn't change anything.

What mods are present on this radio? As far as I know, it's stock. I
bought it used about a month ago from a trucker who stopped trucking.
