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?
