cartridge plays the radio

AFAIK, the Anticable interconnects aren't shielded. That's probably what is causing the problem. Try switching to any type of shielded cable to see.

From the website: "double shielded option is available for use with turntables or extra RFI/EMI protection"

So unless yours have this "option" they are acting like a great big antenna...

Kbo, even if you have the double shielded version, I don't consider that enough shielding for a phono signal. It's just 2 wires coiled around the + conductor rather than 1. You really need 100% shielding here.

I too have had (in the past) radio playing through my LP
turntable system. (At the cartridge clips, the wires coming out of the tone arm to the cartridge approx. 1" ), I twisted the right +&- together and Left +&- together only 3 turns(NOT twisting the left and right channels together) The FM signal stopped at once. And I have never had that problem since.
I hope this works for you,

i had this problem for years, the walkeraudio eliminator seemed to fix it.
