Just Imagine! Two Different Radio Formats For The Price Of One
One of the criticisms that has been levied against conventional – or terrestrial – radio is that so many of today’s stations have mandated playlists and just keep playing the same music over and over. Plus, many listeners say there are just too many darn commercials.

HD Radio or digital radio makes it possible for a station to broadcast several different signals on the same frequency. This technology is called multicsting.
