Have a 97 GL Wagon, stock radio. I have static while receiving distant AM stations, but ONLY when going over 30-35mph. It is there even if the car is rolling with it's engine shut-off. It is dead quiet at a stop or at slow speeds. What makes this strange is - When I apply the emergency brake it goes away!!! Applying the foot brake makes no difference. Also varies with the type of road surface. Sounds like static is building up somewhere. Any suggestions?
