In case of real national emergency then there will more to worry about
than how long a radio's batterys last

Quite - do people expect the radio transmitters and all of the chain
feeding them to run on air, if there is no mains power?

LW was the favourite for an emergency as one transmitter could just about
cover most of the country. And it does have its own backup generators.
Which I very much doubt every DAB or even FM transmitter has. There was
also at one time at least a single DC pair telephone line direct to the
Droitwich LW transmitter, so even with power failure to the lines,
something could be transmitted from London.
