I need a Pro-43 Service manual in a bad way. I have a Pro-2006 service
Manual i can copy for trade. If anything, I need a copy of the schematic
for the boards. I bought a used 43 and the signal is very weak. It's
tuned but takes a very strong signal to break squelch. It has been
bench tested to prove this.

Have you tried asking a RS store to order one for you?
