Browning Mark 3 receiver drift fix.

[Dark Star]

Just a quick update on the state of this repair. What I ended up finding was that my major drifting issue was with the main tuning dial itself. Just years of oxidation that took a lot more elbow grease with a fine burnishing stick and some D5 cleaning the contacts at the capacitor shaft as you had said and she seems as good as new now. I do think that doing the mod described earlier in this thread also helps drastically to hold frequency stable. I talked on LSB for over an hour last night and frequency stayed spot on. That's pretty good for a 50 year old Mark III. Thanks again Chris for all of your help!

Congratulations for sticking with it. When I was in high school I remember an electronics-magazine article about all the kinds of "CC", or cruddy contact can be found in electronic stuff. Sometimes the most-baffling problem has the simplest solution.

I have some inquiries if it’s not too much trouble, guide me about this. These inquiries are displayed underneath here:

Sitting tight for most appropriate response straightaway. I’m excessively confounded here.
