try visiting the Scottish Highlands
I was traveling last week. DAB was non existent not long after Pitlochry, switched to FM, perfect reception and random local radio stations.
DAB is fine if you are in a city. Outside, I'll stick to FM. Also, as stated elsewhere, DAB bitrate has been dropped to support new stations meaning sound quality can't compete with FM. The UK should have upgradedto DAB+ years ago.
