I Pick up a Radio Station when I am playing record

When I am playing record I can hear a radio station coming in very clearly, before I put the record on the turntable. If I play the record I can hear the station at low volume. Can anyone tell what the problem could be? I am using VPI Classic turntable with Dynavector 20X Medium output cartridge (VIP version), and a Tube phonostage. I am also getting a ground loop, but when I remove the interconnect from the phono stage or the turntable the ground loop is reduced. I changed the interconnect and I discovered that the ground loop get louder as I turn the volume up. Any idea what is going on?

It sounds like an un-shielded interconnect.
If you have a long interconnect that is un-shielded, it can act like an antenna and pick up RF (Radio Frequency).
Try a shielded IC and see if that help.

Did you see this thread yesterday? http://forum.audiogon.com/cgi-bin/fr.pl?ymisc&1314849391&read&3&zzlInna&&

Maybe your situation means that you're a super audiophile. Talk about stereo, you've not only got a left and right channel, you've also got analog and FM!

Sorry, but I had to put that in after the other thread.

It sounds like you've just got a shielding problem with your interconnects.

I agree with Z above

I used to live next door to a guy who owned a HAM radio, I could hear him thru my tube amp like he was standing there! I found out some years later, from my brothers friend, that his radio was overpowered and above FCC regulations.

good luck

Give fellow A'gon member Sunnyjim a shout. I can't find his thread but think he had an issue with his Jolida JD9 phono preamp picking up radio signals whenever he played vinyl. I think the culprit might have been the tubes in the JD9 along with the cart he was using. I don't remember exactly but I think he solved the problem. He may be able to help you.

best of luck.

Check the ground wire between turntable and preamp and, make sure it is connected good at both ends.
