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?

I have the same problem if my phono section is anywhere near a power cord or transformer,
I get hum and RF (Radio frequency) problems.
Move your phono section around and see what happens.
Cheers,

Thanks everyone for your responses. I switched out the interconnect from the phono stage to the arm and tried using a heavily shielded coax style interconnect from a company called Straightwire. Problem solved. It was the interconnect that was the problem.

Glad you no longer have to listen to a newscaster talking about the latest political scandal in between the voices of "Sweet Honey in the Rock". This can be so distracting, to say the least.

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!
