Running a radio station is incredibly time-consuming and very hard work, going well beyond simply being a decent presenter. The legislation covering public broadcasting is immense and you need a team of presenters, producers, engineers, cleaners, general office staff, not to mention accountants, solicitors, and advertising and publicity managers. It's a very big task, and not one you can undertake lightly, or even as volunteers, entirely. Add to that the fact that advertising revenue has plummeted for all commercial broadcasters in the past five years and you'd need to be very brave to take it on.
