I'd hold on that one for the moment as there is a DAB (Digital Audio Broadcast) format war going on. Three different systems: UK, France/Germany and the US one..all different. Its a bit like Betamax vs VHS.
UK government has just announced that the analog system will keep going TFN because of this and not be switched off in 2015.
Also DAB has a lot less stations than FM. My side of the pond we only have 10..all RTE state channels. Very few commercial stations have taken it up because of the format issues and costs.
