I am having a problem with electrical static on AM stations. It is electrical static that is audible whenever the car is moving. When I come to a stop the noise stops and re-starts as the car begins moving ( from 1 MPH on up). The static sounds like alternator static but it does not change pitch with engine speed - it is always the same pitch and the same frequency regardless of speed or RPM's.

What is really crazy that when the whole car goes over a rise or dip the noise stops and restarts when the car settles. Individual wheels going over bumps do not cause the noise to stop - as if it is sub-frame movement that makes the static stop.

I have disassembled the power antenna and checked all connections into the radio and all are clean and have good contact.

Any help on solving this is appreciated
Thank you,

 

Hello Rocklandjag,
I have exactly the same problem in my 2001XKR. When the car stops the static goes away and the station is clear. If I rev the engine at stop the station remains clear but as soon as the car starts to move, the static which is a high pitched buzz starts up and will occasionally stop on a curve or going over a hill. Maddening. Please let me know if you solve this problem.
Yours, Ken
