IC cable to address RF coming from nearby FM station

Hello,

The RF signal is coming from an FM station, 97.5, that's about a mile from my house. The tonearm seems to be acting as an antenna. I can modulate the strength of the signal by grasping the tonearm cables at various locations along their length.These tonearm cables are integral with the tonearm and are terminated with XLR connectors. They feed directly into an outboard phono stage. All cables in my stereo system have hardwired XLR  connectors.

I'm hearing the RF thru both speakers.

At one point, I'd considered wrapping these tone arm cables with an adhesive-backed copper foil and then soldering a ground wire to the foil. But the foil would crumple as I tried to wrap each tonearm cable.

Thanks for your inquiry, Phil

Hello,

Thanks to all for your insights and recommendations. I opted for the Canare Stargard because it's designed to address RF issues and it's  inexpensive.  My IC cable is 18 feet long. 

But I'd have to admit that I have not done a thorough job of troubleshooting the internal source of the RF.  I can modulate the strength of the signal by grasping the tonearm cables at various locations along their length. Closer to the tonearm itself  will amplify the signal; farther away from the body of the tonearm will suppress the RF. The tonearm is acting as an antenna.

Thanks again, Phil
