Dead As Betamax
Said it before and I'll say it again.
I note how he admits there is an in-building coverage issue. Guess what, numb nuts, I always listen to the radio either in the house or in the car. In fact, we usually have two or three radios going in the house, offering perfectly acceptable house-wide audio quality. Replace them with DAB and we would experience different group delays from each, plus drop-out (please don't call it "glitch" that merely reveals the level of your technical ignorance). Not an experience we would put up with.
Please give us a digital radio system that is engineered with the end use in mind, thank you.
