2nd Gen Non-Engine/Transmission AM radio noise

[4570]

It seems like my radio is getting more and more static on AM the last few years . I also hear a weired pulsating squeeking noise when i have the radio on a weaker AM station . Now my truck is a 96 so as far as i know i have all mechanical pumps but it sure sounds like a piston pump working . Any one else notice either of these things happening . Arnie

I would check all your radio connections to make sure they are tight. I don't know how the antenna is grounded, but I had a car a few years back with a grounding strap on the antenna. The screw in the grounding strap would loosen, and cause a major increase in static. Good luck

Did you ever get your radio fixed. Mine does the same thing.

Never did find out what the weird noise was . My radio decided to crap out a few months ago . Im wonderring if trying to start the truck with very low batteries would damage the radio . The truck wouldnt start with low batteries so i didnt run it that day and charged the batteries up ,tested them and it sat for three weeks before i drove it again. Thats when i noticed the radio wasnt working . Arnie
