So I have Technics SL-1300 that I picked up recently. Got it set up with my Denon AVR-1602 receiver and a Rolls pre-amp. Sounds pretty darn good. Only problem is for some odd reason it seems to be picking up some local radio station and reproducing it at a very low amplitude whenever the receiver is set to Phono (well in this case there is no build-in preamp, and therefore no specific Phono setting -- but in essence whenever the receiver is set to the turntabnle input) even if no record is spinning. Is my needle picking up radio frequencies? How do I remedy this? Thanks!
