Thank you. for this ! This will help a lot ! You have a wealth of knowledge out there on many radios ! No toilet paper rolls from me ! I will make time to continue reading. I am only as smart as the knowledge I know. Always willing to read concepts.

Now, I have got the AR-3500 working "enough" for now. All 3 I have are the same.

Note to others who may have this issue: I isolated leg 14 of IC2 (2902N) will open the squelch. I removed D25 and removed the warble of overload. Still a tad hot, but usable with RF gain at 4 O'clock. This of course isn't the solution to the problem. Radio operates fine if you don't use squelch and don't mind not having the fully AGC working.

Will keep at it after cap changes.
