Completely vanished over night and website gone too.

....Ever since they first came on air they'd continuously put out silence on 101.4 FM sometimes for weeks on end, but I understand this was not the reason why and they failed to meet the deadline to submit their Financial Report (again).

I remember a year or 2 ago all the union jack stations disappeared over night on dab, there was empty space, we listened to union jack dance a few times, read on a forum it had gone, all the other stations had gone along with it. I suppose may of been known it was in trouble, unlikely to say anything through the station, usual thing of keep the listeners in the dark.
I guess with a community station it will likely go off air if theres no one there to rescue it, with local commercial radio stations there was a bigger company there to buy them up and take them over.
