Getting rid of fm stations

Sheilded dedicated power line to your rig? I'm only guessing.

Have you tried RF Stoppers (ferrite clamp) by Audioquest? These little magnet cylinders clamp onto your interconnect and block FM noise. Radio Shack also made a version. The Cable Company web site has the RF Stoppers for sale:

Have you tried twisting your ICs going from turntable to phono preamp? It worked for me.
