Wisconsin Public Radio is proud to be among the first radio stations in the United States to implement the new "HD" digital radio service. HD Radio promises to increase the quality and reliability of our signals while adding additional features.

Many of the WPR stations around the state are now equipped for "HD Radio" - the high-definition digital radio service. HD Radio is now available from these WPR stations: WHA-AM 970 Madison WERN-FM 88.7 Madison KUWS-FM 91.3 Superior WHRM-FM 90.9 Wausau WHAD-FM 90.7 Delafield/Milwaukee WPNE-FM 89.3 Green Bay WLSU-FM 88.9 La Crosse And in the near future, we plan to add HD signals to WLBL-AM Auburndale, WHDI-FM Sister Bay, WHWC-FM Menomonie, WHBM-FM Park Falls, WHLA-FM La Crosse, and WHHI-FM Highland. 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 listener 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. If you'd like to shop for an HD receiver, see our Store Information Guide in the right column. Many stores throughout Wisconsin and online are now stocking HD Radio receivers and prices are rapidly declining. 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).
