At present, DAB coverage is unacceptable... Even driving into Glasgow, I frequently lose signal. On a 40 mile drive yesterday, it was so bad I had to switch to my iPhone for music. The DAB symbol onscreen shows signal strength, or a grey FM superimposed if DAB drops out. Digital switchover will hopefully remain some time off. The irony is that when there is a good signal, quality is excellent as is the track info.
