WBDG

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.

As the 1970s waned, WBDG began to add after school radio shows. Pop music and rock started to air. By 1979, WBDG was broadcasting 15 hours per day, five days per week and from 9:00 AM-Midnight on Saturday and Sunday. Student operators even kept the station on the air on holidays such as Thanksgiving and Christmas with no automation system.

During the days of disco, WBDG earned a few ratings points in one of the books. WBDG was the only disco station in Indianapolis. A few of WBDG's staff members had also gotten an advertising agency to donate to WBDG 35 billboard advertisements. “Disco 91” billboards were across the city. When disco died, WBDG adopted a popular music and rock format. In 1986, the station was granted its current stereo license after raising the money for stereo broadcast equipment in a first-ever WBDG Radio Marathon.

In the early 1990s, popular music was shifting toward an increasingly esoteric and unconventional bent. In emphasis of this expanding scope of sound in the mainstream, WBDG adopted the moniker "The Radio Spectrum". Some of the most dynamic set lists of this era came from a show entitled "What Not", an innovative modern rock show pioneered by student Paul Dworak. In 1995, WBDG expanded to 24 hours a day, every day. On June 1, 2002, WBDG re-launched as Giant 90.9.

In July 2020, the FCC granted an eight-year license renewal that will not expire until 2028. WBDG began broadcasting in both analog and HD Radio in January 2018.

The station broadcasts with 0.4 kilowatts of both vertical and horizontal power at 78 feet (24 m) of height above average terrain serving primarily Western Marion and Eastern Hendricks Counties. The station is licensed to Indianapolis. More information can be found on the FCC's search page for WBDG-FM
