WDCB (90.9 FM) is a public radio station broadcasting a jazz format, serving primarily the Chicago area, and beyond through its streaming audio. The station is licensed to and owned by College of DuPage, in Glen Ellyn, Illinois, United States, and mostly features live and locally hosted programming, along with select programs from NPR, PRX, and United Stations Radio Networks. Music from WDCB can be heard on CAN TV channel 42 in Chicago. History WDCB began broadcasting July 5, 1977 and was originally a part-time station, sharing time on the frequency with WEPS. The station's call sign stood for "DuPage Community Broadcasting". In its early years, the station aired classical, jazz, and folk music, College of DuPage courses, community affairs, and entertainment programming. The station began full-time operations in October 1987, after an agreement was reached for WEPS to move to a new frequency. Throughout the 1980s, WDCB was also used on the Cablevision of Downers Grove's Local/Public Access Channel. By the late 1980s, jazz had become the station's primary format. Since then, WDCB's format has included a diverse variety of musical genres, including blues, roots rock, bluegrass, Celtic, folk, big band, Afro-Cuban jazz, and world music, along with old-time radio shows, though jazz makes up a majority of the station's programming. COD courses continued to air on the station until 2001. Classical Confab aired Sundays until late 2005. WDCB is also the home of Those Were The Days, the long-running old-time radio program that used to be hosted by Chuck Schaden. In 2009, Steve Darnall took over as the second host of the show. The show was announced for years by Ken Alexander, who died November 5, 2022. As the result of a 2016 agreement with Chicago Public Media, WDCB's programming is now also heard on WRTE 90.7 FM, from a low power 6-watt signal located on Chicago's near-west side. While WDCB's primary 90.9 FM signal does reach all of Chicago, the 90.7 FM signal offers better reception for many WDCB listeners on the west side of Chicago, as well as Chicago's near-north and near-south side neighborhoods. Programming WDCB broadcasts more than 130 hours of jazz every week. Since 2000, John Russell Ghrist has hosted the Saturday afternoon big band program Midwest Ballroom. Steve Darnall hosts the long running old-time radio program Those Were The Days, which airs Saturday afternoons. WDCB's extensive blues lineup includes a 10-hour block of
