Marty,
Might be a waste of your time but I would go to HD or Best Buy and buy some cheap twisted pair speaker cable and see if it solves your problem. Flat ribbon speaker cable is prone to RFI,... works as a good antenna.
Another thing to check out is the radio station. Do you know for sure which one it is. If so give them a call and ask to speak to their engineer. Ask him if they are broadcasting also in AM. Also explain your problem to him. He may be able to help. At the very least he will give you the broadcast transmitting frequency.
