Are you sure it’s not your receiver that’s crap?
Never mind DAB, here in Germany my analogue radio only seems to receive 1980's music.

DAB, still crap after x years. A dead duck I think...
I’ve three receivers, (one car and two portable). Outside of London it is so patchy, it only works when the car is stationary or inside a building, it is limited to certain areas. Furthermore, the bit-rate on some stations makes the sound worse than FM.
