well surely it must be the rf amp tranny
if you have a genny trace it through the first stage, should be simple

Connector checked out ok. I bypassed the BNC and put the freq
generator on the BNC points on the IF board. Still the signal had to
be 100 microvolts to break squelch. RS does not carry the Service
Manual OR parts for the 43 any more.
Does anyone have or know someone with a damaged Pro-43 that has a good
IF board? Till then I'm still poking around...

sounds like it
a broken connection between the antenna connector and the board, is the
BNC socket also loose?, good sign

Thanks Mike. I'm looking into that now. It has to be kind of simple
to
fix since the radio IS working.

a common problem is the wire to the pcb from the socket twisting and
breaking the joints and the first surface mount coil going o/c or
lifting.

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.
