Easy radio fix
 
Because I like the sound of my small block I seldom play the radio. Then last year I turned it on and the static coming from the volume knob was extreme. I was given the suggestion that a few times of turning it off and on might fix the issue of mind corrosion build up. It didn't. I left the power off and turned the radio to the on position and then rapidly adjusted the volume knob from low to loud many, and I mean many times. Surprise, my radio now works as it should without the static. This is my kind of repair. Thanks to those who suggested the off-on sequence. I just needed to be more extreme using their excellent advice.

You burnished it. Surprisingly, this is a "fix" that I suggested many times professionally and it worked maybe 70% of the time. The other 30%...it's the military, they abuse hell out of this stuff lol. In a seldom used mode, the small amount of corrosion made just enough of a problem to matter. The robot "lost" connection. In truth it was never being asked to make the connection.

Having the users switch to that mode once every six months (like they were supposed to anyway for training lol) or so resolves it.

I have 9 or 10 old CB and ham radios inherited from my father. Most were brought back to life by cycling the volume knob, but a couple I had to disassemble and spray with tuner cleaner. My guess is tuner cleaner may be hard to find as today's electronics are electronic tuners rather than variable resistors.

Gold standard for cleaning electronic parts.

I tried it, and it left an oily residue. Very disappointed after all the hype.
I usually use flux remover. Tech Spray is a good brand.

I had the same issue with my 72- after paying a known radio rebuilder to upgrade it. When it sounded bad he said they only installed a new board and that the volume pots are discontinued. One of the few jobs I ever subbed out and got lousy service. Anyway, I sprayed some DeOxit done the pot shaft a little at a time so as not to have overspray all over. Worked it back and forth a dozen times and it solved the problem. The radio upgrade by the shop, not so impressive and the original radio when it worked was better.

My '67 radio is very static-y, so I'm going to give this a try and I have a can of De-Ox-It too. You're merely spraying it down the volume knob's shaft while installed in the dash?

Yes. Remove the knob and then spray a small amount on the shaft, towards the radio. Work the volume shaft back and forth 20-30 times. Spray an additional small amount on the shaft and work the volume shaft back and forth 20-30 times. I bet your volume static disappears.

Also, slide the AM/FM button up and down like 50 times, it will cause static and intermittent operation also.
