Unwanted radio signal from turntable

I have been plagued by a unwanted AM radio signal that appears when I am using my turntable. While it can't be heard when music is playing it is very annoying to hear a newscaster talking about the latest political scandel inbetween the voices of "Sweet Honey in the Rock".
My system is AR pre, Phonomena phono, Clearaudio turntable. It is in this chain that the problem occurs. The culprit seems to be the interconnect between the turntable and the phono stage. If I disconnect it from the turntable the radio station remains, so not the turntable or ground. If I disconnect it from the phono stage the radio signal disapears. I thought that it was due to a poorly sheilded interconnect (Kimber). I tried a different interconnect and the signal returned, any ideas from the analog gurus on how to deal with this?

Reminds me of the Partridge Family episode where Lori Partridge was picking up AM stations in her mouth after getting new Braces on her teeth.

Agaffer most people on Agon complain of getting bad AM reception, so in your case it's like a bonus? :)~

I'm w/ Twl on the Grounding situation, & Eldartford on cleaning the contacts if they are dirty?

Did changing interconnects lessen or strengthen the signal?

I would still take Audiophanatik advise just as a precaution should you smell any pea soup as your table turns??? Definately not the the turntable you want to play your LP's backwards on to listen to subliminal messages!
