WKJG began broadcasting November 15, 1947 under the ownership of Northeastern Indiana Broadcasting, itself controlled by William Kunkel. Kunkel was also the publisher of The Journal Gazette; the call letters are derived from both entities. Initially a Mutual affiliate, WKJG joined NBC Radio in 1956, after WOWO dropped NBC to go independent; this brought the station in line with sister station WKJG-TV, which had been an NBC-TV affiliate since going on the air in 1953. The WKJG stations were sold to the TruthPublishing Company of Elkhart in 1957; in 1963, the stations came under the Communicana banner. After WKJG-TV was sold in 1971, it was decided to change the call letters of the radio stations, citing the perceived difficulty in saying "WKJG". As a result, on October 1, WKJG, by then a top 40 station, became WMEE, with sister beautiful music station WKJG-FM becoming WMEF. The following year, WMEE ceased its NBC Radio affiliation. The station's owner became Federated Media in 1977. The station changed its call letters to WQHK and adopted a country music format in 1979, with WMEE and the top 40 format being moved to WMEF's former 97.3 FM facility. In 1991, the station moved to emphasizing classic country, carrying the ABC Radio/Satellite Music Network -distributed Real Country network; two years later, Federated Media launched WQHK-FM with a more contemporary country music format. The AM station continued with classic country until 1995, when it changed to a talk format. The station became adult standards station WHWD on March 26, 1996, with most programming being provided by ABC's Stardust service; some of WQHK's talk shows were moved to sister station WOWO. WHWD adopted the current sports format, initially provided by One on One Sports, in September 1998. To reflect the One on One affiliation, the call letters were changed to WONO in November 1999; however, the following August, the station switched to ESPN Radio. The WONO call letters were nonetheless retained until November 3, 2003, when the WKJG call letters, which had been dropped by channel 33 a few months earlier, were restored. From 2012 to 2018, the station was simulcast on then-sister FM station 106.7 WFGA. This arrangement ended in May 2018 with the station's sale to Swick Broadcasting Company, and subsequent switch to classic country.
