WHAT IS HD RADIO?

http://www.nautel.com/HDRadio.aspx

HD Radio is a new technology that enables AM and FM radio stations to broadcast their programs digitally, a tremendous technological leap from today's familiar analog broadcasts. These digital broadcasts provide listeners with radically improved audio quality and reception and new data services. Signal fading, static, hisses and pops are a thing of the past. Data services such as displayed song and artist information, weather and traffic alerts and much more will revolutionize the way you experience AM and FM radio. And it's all FREE for consumers, just like today's analog AM and FM radio.
