It is also possible that it is coming from the internal tonearm wiring. These wires are normally unshielded and can pick up radio stations. Sometimes grounding the tonearm tube can help this, but you have to be very careful not to interfere with the free movement of the arm. Sometimes grounding the metal areas around the bearing or base of the tonearm can work instead. That would be preferable to having any additional wire touching the arm tube.
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?
