Rega P25. Getting radio signals thru interconnects

Seems to be picking up radio thru the interconnects.
Any suggestions?
You'll want to read through this thread, in which a similar problem was successfully resolved:

That's an option you usually have to pay extra for.
G'day, if ferrite clamp on chokes don't work, improved earthing (grounding) is normally the answer.

These sorts of issues can be bedevilling but usually can be solved through proper investigation.

Try connecting the TT earth wire to different chassis points. That may give a clue. Regards, Fap.
