HD Radio is a brand name of a method of digital transmission of both AM and FM stations.  The HD Radio system is unique in that it allows stations to broadcast high quality audio (no hiss) and offer a variety of text-based services (what song is playing, who played it) much like satellite radio.  HD also offers the option of broadcasting additional channels without changing to a different frequency.  In the near future, jazz89 KUVO will be able to offer 2 channels of programming at 89.3.

HD stands for "Hybrid Digital" and not "High Definition" as is commonly thought.  HD Radio is a trademarked brand name.  The FCC decided that HD would be the standard, giving AM channels more clarity and FM channels the opportunity to multicast.  As of July 23, 2007, more than 1360 radio stations across the country are broadcasting with HD radio technology and more than 600 of those stations are offering multicast channels.  Like traditional AM and FM stations, HD radio programming is free, but a new radio system is required.  Right now, HD is readily available for car stereos and a limited number of desktop/home HD radio brands are available.
