HD Radio is a new technology that allows broadcasters to seamlessly transmit digital quality audio
alongside today's analog-based broadcasts - a tremendous technological leap from the familiar "analog"
broadcasts. These digital broadcast channels provide listeners with radically improved audio quality and reception.
Signal 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 are now possible and will revolutionize the experience
of AM and FM radio listeners. And it's free - just like today's analog AM and FM radio.
Little or no change in listening behavior is required since all the local radio station dial positions will
remain the same. You'll simply tune to your favorite programs and stations, and receive them in
either a digital or analog format depending on your radio. Because new HD Radio stations will begin their digital
broadcasting using a "hybrid mode" (transmitting digital and analog signals simultaneously), you'll still be
able to pick up our broadcasts on your analog radios, but you'll be able to seamlessly upgrade to digital
at your own pace. HD Radio technology was developed by iBiquity Digital Corp and approved in October 2002 by the
Federal Communications Commission.

The WPR HD Radio stations are being upgraded with state Building Commission funds, contributions from
public radio listeners, and through grant support from the Corporation for Public Broadcasting (CPB).
