Phono stage picking up radio signals?

The strangest thing happened this evening. I just hooked up my Whest phono stage and as I was letting it warm up I turned up the volume slightly to check the noise level and noticed a strange noise coming from the speakers. At first I thought it was a ground loop hum or some feedback, but when I put my ear to the speaker I distinctly heard music. I turned up the volume a bit and to my surprise I could hear and identify the song playing, followed shortly after by DJ banter. It was obvious I was picking up a radio station, but I don't have a tuner or any other radio device in the home. Can anyone give me a clue as to what might be going on.

I am not familar with your phonostage so this reply may be redundant but if it has tubes try replacing them.

Some tubes play radio stations and others don't I don't know why but thats the way it is.

If that doesn't work then you have a grounding problem in your arm or shielding problem in your system somewhere.

One thing you can try is installing ferrite beads over the inputs of the phono. They must be inside the preamp to be effective. They don't work went put inside interconect RCA's.
