Pro-2020 Help and Schematic Needed
 

I have a Pro-2020 that works well with a couple of exceptions.

1 - while scanning there is a slight low volume "popping" sound as the unit
scanner from one memory to another. It only does this while scanning. When
it stops the sound stops as well.

2 - The audio is fairly raspy with anything other than a low volume.


Any input is greatly appreciated since I don't have a schem


Tnx,

Rob

I HAVE A SERVICE MANUAL
