The Quad-Cities allocation for 104.9 MHz dates to 1977, when the city of license was Geneseo, Illinois. The station signed on as WGEN-FM, the FM sister station of WGEN-AM (1500 kHz). The station formatted country music, along with community and farm news, local sports and St. Louis Cardinals baseball.
In 1996, both WGEN-AM and WGEN-FM were sold to Connoisseur Communications, owner of KJOC, KORB, WXLP and KBOB. For a time, the FM station was a repeater of KJOC's AM signal, while the AM signal was a simulcast of KBOB (at the time, located at 99.7 FM). By 1997, ownership of the AM and FM frequencies were split, and Connoisseur moved the city of license to DeWitt, Iowa; a new transmitter tower was built near Long Grove (about 7 miles south of DeWitt), and the studios were moved to Davenport in anticipation of its first new format under the new ownership.
Lite 104.9 FM-KQLI (1998-2000)
KQLI employed a soft rock format at 104.9 for about two years, starting in March 1998. However, the station had minimal listenership, primarily due to its small coverage area and competition from the more powerful KMXG-FM.
The Country era (2000-2007)
In March 2000, when KQLI and sister stations KBOB, WXLP (aka 97X), KORB, and KJOC were sold to Cumulus Media, plans were already being formulated to revamp several of the company's radio stations, including 104.9 FM. The plan involved scrapping KQLI's soft rock format and moving KBOB's country format from 99.7 FM to 104.9 FM.
KBOB's modern country format, in use since it began in March 1994, remained the same until November 2001, when the station adopted a classic country format under the slogan "Great Country 105." Although "Great Country 105" had a loyal audience (as it played songs from artists such as George Jones and Merle Haggard), the ratings remained low.
In March 2005, the station switched back to a modern country format, dubbing itself "New Country: The River 104.9," but listenership remained near the bottom of the Quad-City market's ratings.
Rock 104-9 (2007-2014) and return to country (2014-present)
When things were moved around again in 2007, Cumulus' modern rock format, which had been at WXLP for several years, moved to 104.9 FM to create "Rock 104-9." Included with the switch was 97 Rock's "Dave and Darren in the Morning" radio show. Other on-air personalities include Bill Stage and Sean. The station also broadcasts syndicated shows Hard Drive and The House Of Hair. In addition to its music programming, KBOB broadcast Chicago Bears football games from 2007-2013.
On August 30, 2013, a deal was announced in which Townsquare Media would acquire 53 Cumulus stations, including KBOB-FM, for $238 million. The deal is part of Cumulus' acquisition of Dial Global; Townsquare and Dial Global are both controlled by Oaktree Capital Management. The sale to Townsquare was completed on November 14, 2013.
On July 8, 2014, 104.9 began formatting a modern country format, marking the frequency's return to country music for the first time in seven years. The station used the brand name "The Hawk," and launched with a 10,000-song marathon. The new country format now leaves the Quad Cities without a single modern rock station. Also on July 9, KBOB-FM changed their call letters to KQCS.
