I seem to get a lot of clipping when I listen to Dab Radio (even when stationary). Its hard to explain, I don't get any drop outs and the quality of sound generally seems ok... but I keep getting this frequent Clucking sound (as if you are listening through blown speakers).

If I listen to any other source (CD / MP3 / FM) the sound is fine, with no issues at all.

Does anyone else get this... is it just purely DAB reception?
