I have a Pro-96 that's about 12 years old now. It's been "rode hard" but not necessarily tossed around. A while ago, I noticed that 800 MHz receive was distorted. By playing around with searches, I found that if I added 6.25 kHz to the receive frequency, I could receive reliably again. So, I reprogrammed the EDACS system I listen to a lot with the offset frequencies. The other day, I found the thread about VR4. I moved the pot and was able to receive on the normal frequency again, but it didn't seem to warp the frequency fully down. I still get signals on both, as though the reference oscillator is half-way between the two frequencies.
I had the service manual at one time, but haven't seen it in years. I don't recall reading about any alignment points to net in a reference oscillator, anyway.
Have any of you ever come across this, and if you were able to address the problem yourself, what did you do? I have a small radio shop with a service monitor and other instrumentation, so I would be taking care of it myself.
Thank you.
