I have DAB and agree with all Ian has said.
Funny how the static DAB radio in the house drops in and out of stations, whereas the one in the car which is belting all over the place, barely misses a beat (sorry now I'm punning)
With al those stations you can select something that fits what you want to listen to.
I hardly ever listen to the DAB in my car. Cos there's something better. 18Gb and growing of my choice of music on the HDD. No yacking presenters, ever
