The third Big Broadcast will be happening at the end of National Hospital Broadcasting Week.  It will be a 24 hour live show to close the week that celebrates all that's great about hospital broadcasting in the UK.

The show will be hosted by Richard Smith and a team of presenters and will include a chance to hear some of the highlights of the National Hospital Radio awards 2013.

Those statons taking part will battle each other in the A to Z of Pop Trivia Challenge and there'll be plenty of opportunity for requests.
