In fairness to DAB, I don’t think it’s any worse than FM in many parts of rural Scotland. There are whole swathes of the country between Glasgow and Inverness where FM vanishes.
I get surprisingly good DAB down here in the arse-end of the South Rhins, presumably because I have line of sight over the Irish Sea to a transmitter in Northern Ireland.
Never had any issues with FM in Yorkshire
But most of it is probably lease remote the Scotland
Probably only north York Moors and the sales comparible
