WBDG (90.9 FM) is a high school radio station broadcasting a Variety format from Ben Davis High School in Indianapolis, Indiana, USA. The station is currently owned by Metropolitan School District of Wayne Township.
WBDG is one of the first radio stations in Marion County to be owned by a school system and operated by the students of that system. A construction permit was obtained to build a tower on top of the newly constructed "new" Ben Davis High School in September 1965, and, on February 14, 1966, WBDG came to life with its first regular broadcasting day. The station had a radiated power of just 10 watts.
Early programming on WBDG consisted of a modest schedule of educational programs aimed at the township elementary schools, community news and a lunch-time dance party. The station broadcast only during school hours and on athletic event nights. Competition for the handful of disc jockey slots each week was very fierce.
In the early 1970s, station management applied for and was granted a power increase. The station's radiated power was upped to 320 watts. Channel six (WRTV) insisted that WBDG move its antenna and transmitter to the tower farm near St. Vincent Hospital on Indy's Northside. The new transmission location proved undesirable as the station could barely be received in its own control room. In 1979, the FCC granted the petition to move the station back to Ben Davis. Part of the FCC's construction permit was to increase WBDG's radiated power to 400 watts. A 78-foot (24 m) tower was built on the school roof, and the transmitter was moved to a fan room on the second floor of the building.
