I have a Radio Shack Pro90 which I am in need of a service manual or at
least a schematic for this thing. The squelch is stuck open and as a result
only the trunking scans properly. Normal channels won't scan because of the
problem it has. If someone has either available and can scan the
appropriate section I would greatly appreciate that. I'm not sure of the
Uniden version of this, but most likely this is the only thing that may be
found. I'm sure Rad Shack never did release any information on this thing
to anyone.

Thanks in advance for any assistance.

Steve
