Dead As Betamax
The DAB spec was good for squeezing in large number of channels, but it suffers from a number of effects that make it a far less satisfactory listening experience than FM.
What we need is a standard that allows for graceful degredation in sound quality in poor reception conditions, a more robust modulation/coding scheme, lower power consumption so a radio can use disposable batteries for a reasonable length of time, and a fixed group delay so that all radios in the house (say) output the same sound at the same time instead of sounding like a comedy echo/delay special effect.
