It has been a long time, but I used to put a pad (around 6dB?) in front of the receiver, then see if the noise still comes through. If you still hear it then it is generated external to the RX. if it goes away, then your Rx is getting overloaded. If you have an RX preamp, have you tried it without? Also, you used to be able to get small clip-on ferrite chokes at Radio Shack, A bunch of those on the cat-5 audio/control cableing might help clean that up. Last bunch I got came from AllElectronics. YMMV!! Good Luck, Eric
