And not just when it's tuned to Radio 1.

There's a fast warbly wawaawawawawawawawa noise coming from the actual circuit board itself, independent of the volume. It's definitely not coming from the speakers, and it's always done it from new. I didn't notice it at first, but it didn't take long to become really annoying.

I got it a while ago when DAB was reasonably new, maybe 5 years or so, but I just started thinking about it again.

Any ideas? How could the board itself be making a noise?
