The Quad Cities allocation for 104.9 MHz dates to 1977, when the city of license was Geneseo, Illinois. The station signed on as WRSQ-FM, the FM sister station of WGEN-AM. The station aired country music, along with community and farm news, local sports and St. Louis Cardinals baseball. The call letters were changed to WGEN-FM on October 6, 1980. 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. 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, 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 an adult contemporary 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.
In March 2000, when KQLI and sister stations KBOB, WXLP, 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 AC format and moving KBOB's country format from 99.7 FM to 104.9 FM, as 99.7 FM flipped to Top 40/CHR as "B100". 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, the ratings remained low. In March 2005, the station switched back to a modern country format, dubbing itself "The River 104.9," but listenership remained near the bottom of the Quad Cities market's ratings.
Rock 104-9 (2007-2014) and return to country (2014-2016)
In March 2007, Cumulus moved WXLP's modern rock format to 104.9 FM as "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 to 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 was 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 9, 2014, at 6 a.m., after playing "Brain Stew" and "Jaded", both by Green Day, KBOB began stunting with Christmas music. At Noon, the station flipped back to country as "104.9 The Hawk", launching with 10,000 songs in a row, with the first being "Drink to That All Night" by Jerrod Niemann. At the same time, the callsign was changed to KQCS.
KIIK 104.9 (2016-Present)
The Hawk failed to take listeners from rival WLLR, garnering a mere 2.0 in the last Arbitron ratings under the country format for July 2016, miles behind WLLR's 18.1 rating. On August 29, the station began stunting with songs with the word "talk" in the title, before debuting a classic hits format as "The New KIIK 104.9". The first song played under the new format was "Eye of the Tiger" by Survivor. The KIIK-FM call letters were adopted on September 7th. On the same day, WYEC, an oldies-leaning station, dumped its format for adult hits, meaning that KQCS would have no direct classic hits/oldies competitor in the Quad Cities market, although KMXG, an adult contemporary station, devotes its weekend programming to music of the 1970s, the 1980s, and the 1990s. The station changed its call letters to KIIK-FM on September 7, 2016.
