Correct me if I'm wrong, but I made the Radio Times alter their website to make it clear that no such thing as a portable DAB receiver exists and, reference to a DAB transmission map makes it clear that a car(mobile) receiver would be about as much use as a chocolate teapot!

There will be one very soon now:
