Radio World published an article late last year about a group that's trying to do something I'm surprised no one had proposed before - expanding the FM broadcast band.
The idea would be to make more room for LPFM, relieve overcrowding on the AM band, and create more opportunities for growth on the existing FM band by extending it into the old areas for TV channels 5 and 6 that are being vacated by the switch to digital. It would also create an opportunity to finally create one or two standard frequencies for emergency use that could be worked into radio designs by manufacturers.
