Re: The fundamental issue with DAB
Indeed. A couple of years ago I won (!) a nice Sony DAB portable. I used to listen to BBC radio for an hour or so before I got up, and at the end of the first week the radio went off. I thought it was faulty, but it turned out it had ground its way through the 4xAA cells in just 6 hours of listening. And this was at a volume level carefully adjusted so it wouldn't wake the family. I replaced the batteries (genuine Duracell) and tried again and got the same result. Batteries weren't cheap even then, so I put the radio away and went back to my analogue FM radio which runs for several months on the same type of battery.
It's the same story with the bathroom radio, a cheap AM/FM radio from Amazon. I can't remember the last time I put new batteries in!
