Mu-So Radio keeps cutting out

This is likely to be linked to Nick from Suffolk's issue, but for the bulk of the day I leave my mu-so tuned to Radio 2 and just recently it has started cutting out for a period ranging from 1 to 10 seconds,

The mu-so is hard-wired, it is not my broadband as I have no issues listening to streaming radio on my computer or Roberts Stream - anybody else having similar issues ?
