Are oldies goodies?
The station I've been hugely impressed with over the past few weeks is In Demand Radio, on the Liverpool/Wrexham/etc multiplex. They've got some well-known names, but the programming is really professional, feels spot on for their audience, and it feels like they're growing quite fast in awareness through social media and word-of-mouth. It's not a "standalone" either - it seems to have quite a few synergies with In Demand's existing festivals/events business. I hope it continues to grow.
Matt, there are plenty of people already starting legal radio stations which actually broadcast to their own micro-neighborhood thanks to license-free Part 15 radio broadcasting. While online radio is certainly fun the costs of streaming, music royalties, etc., can be a bit off-putting. Besides, there's something about being able to pick up your own radio station on an actual radio! My renewed interest in Part 15 radio came when I built up a campus station for a local high school and I took all those resources and built a reference website, Hobbybroadcaster .net, for not only educational institutions but also hobbyists.
