There’s many places in the U.K. where AM is the only way to listen to radio. Even in the Lake District FM is patchy, DAB often non existent and no mobile signal for streaming.
Same in the Highlands of Scotland and parts of Wales.
It seems to me that the air are talking themselves into the end of AM because they don’t want to pay for it. Gone are the days when it was a public service operated by the BBC. Hard luck to those who can’t listen on DAB or stream.
Best read a book instead
