WKSU(FM), Kent, Ohio has added a new HD4 Radio channel to its broadcast, becoming what it says is the first non-commercial station to do so.
The HD4 channel carries news and information, airing programming from WKSU, NPR, PRI and other public radio sources. It joins the WSKU HD main channel (a mix of classical and news), folk on its HD2 and classical on its HD3 channels as well as the analog broadcasts.
For listeners, WKSU has a video on the right side of an HD web page explaining how to set up and tune an HD Radio, a Sony tabletop in this case.
The Kent State University licensee began transmitting an HD Radio signal in 2004. WKSU is now broadcasting four HD Radio channels over 89.7 WKSU in Kent, and via repeaters at 89.1 WKSV in Thompson, 89.3 WKRW in Wooster, 91.5 WKRJ in New Philadelphia, and 90.7 WNRK in Norwalk.
CBS-Radio-owned WJFK(FM),Washington became the first station in the nation to add an HD4 channel; It began airing sports talk on its HD4 just before the spring NAB show.
