I can't think of anyone as lighting 90.8 supreme 99.8 venture 99.6 and RJR are not on dab anyone know anything that has?

Maybe it's because most of their listeners are on FM. The fact they've been on those frequencies so long negates the argument of no frequencies in London. Ofcom might as well license them.

Question is would they want to be?

The route to DAB is easier but how popular would that be?

It's a good question and no, not as far as I'm aware. Which is quite surprisingly actually come to think of it....
