I just today unpacked my R8500 from my recent move and got it reinstalled in my new office. Everything else in the shack seems to work fine but the R8500 went wonky. After a minute or two the frequency display started flashing (the characters, not the light). A sharp sound popped out from the speaker that sounded like a power spike or something. It would clink then the squelch would open for a brief moment. It would do this for a few moments then go away.
I tried a CPU reset (hold the MW button down as the radio is turned on) and it seemed to work fine for a few minutes. Somehow this seemed to fix the dial light!
A few minutes later the weird clicking/squelch comes up again. It goes away after a while. This seems to come and go at fairly random times.
This radio has worked fine for the last 5 years or so that I have had it, I have never seen this behavior before.
Could this be a PLL unlock issue? Is this something I can fix without a service monitor/signal generator?
