Correct. People shouldn't get confused with this. If you're listening on FM it is an ANALOGUE signal, DAB is delivered digitally. I can't see any suggestion of engineering work at the Croydon mast that might be affecting this. Probably the best thing to do is check reception on the co-sited stations; Capital, Heart, Kiss, Magic and Smooth to see if you're having reception issues with these as they're all from the same transmitter. If those are fine, it might suggest it is a local, or pirate interference - LBC have had many problems in the past with a pirate broadcasting around 97.1FM.
