I have two DAB radios, one is part of a Sony mini hi-fi system and I can gett all the stations on that. I also have a battery/mains DAB radio which I use outdoors. I normally listen to Radio Wales but yesterday whilst I was listening to it on the portable radio, it suddenly cut out and I could not find it again. Only available in FM. I re-scanned the stations in again but it came up with "Not available" on the Radio Wales station. I know it's still on DAB because I can get it on my hi fi. Any suggestions please?
