IC cable to address RF coming from nearby FM station

That's a good thought.

@converge  Did you troubleshoot the problem to be the cable? If not, it could be a component, any other cable, power supply.

Check posts from @spatialking-

In reading about one of his experiences with a neighbor who had some massive amateur radio setup near his place he had to seek out a heavily shielded cable- just don’t remember which type or brand.

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

What components does the balanced cable connect to?

Sounds like you need shielded tonearm cables.
