We recently moved into a new house in a different part of town and now that I have our PA set up in the basement, I'm getting a couple of radio stations (not loud, but enough to be of annoyance) coming over the PA. I guess this is being picked up by the mic and keyboard cords.

Anyone have any ideas how to eliminate this rf interference? P.S. All the cords are of the right kind, kbd. cords for the kbd., mic. cords for the mics., all properly shielded, grounded, etc. Thanks.
