KBOB was a radio station licensed to Davenport, Iowa. The station's frequency was 1170 kHz, and broadcast at a power of 1 kW. Its transmitter was in Knoxville Road just outside of Milan, Illinois. KBOB was owned by Townsquare Media, with studios located on Brady Street in Davenport.

The station went on the air in 1946 as KSTT. It was the Quad Cities' top 40 station from the mid-1950s until 1986, changing its call sign to KKZX in 1984. It then became an easy listening station, before returning to the KSTT call sign as part of a 1987 change to oldies. The station simulcast WXLP from 1989 until becoming a sports radio station in 1992; it became KJOC in 1993. KJOC moved to a talk radio format in 2003, and an oldies format in 2008. After Cumulus Media swapped its Quad Cities stations to Townsquare Media in 2013, the station briefly returned to sports in 2014; when that format and the KJOC call sign moved to 93.5 FM later that year, this station became classic country station KBOB. The sports format again returned to the station in 2019, remaining until Townsquare shut down KBOB in 2025.

The station signed on July 7, 1946, as KSTT, broadcasting from the Hotel Davenport in downtown Davenport. Format was typical of the era, with big band and vocal pop, along with news, sports and farm markets.

It was not until the mid-1950s—when it began playing the then-new Top 40 genre—that the station really took off in popularity. Disc jockeys made liberal use of listener requests and call-in contests. If there was a live broadcast or news happening in the Quad Cities, listeners were sure to spot the "Big Red" mobile news cruiser. KSTT also polled listeners on their favorite current songs, which disc jockeys then presented in a weekly countdown program. Quad Cities area servicemen in Vietnam had tapes of KSTT programming sent to them.

The station, which moved in 1963 to 1111 East River Drive in downtown Davenport, had a large window in its studio, where motorists could see their favorite on-air disc jockeys broadcasting. Listeners today remember such radio personalities as Jay Gregory, Mike Kenneally, Michelle Coleman, Tom Clay, Bill Young, Greg Garron, Bryan Bradford, Dave Shropshire, Lou Gutenberger, Bobby Rich, Bob Bateman, Ruth & Fred, "Spike @ the Mic" O'Dell and Jim O'Hara, each of them presenting the current Top 40 hits in an entertaining way. Members of the station's award-winning news department included News Director Jerry Reid and reporters Dave Douglas (Tom Hosmanek), Gary Hummel, Paulee Lipsman, John Cloghssey, Dan Kennedy, Dan Potter, Jack Gabor, David McAlary & Fred Manfra.

KSTT listeners became participants as well as listeners, phoning in news tips, requesting songs. They attended KSTT-sponsored "hootenannys", sock-hops, "Smallstars" basketball games, picnics, concerts and "Good Guy-A-Go-Go" dances & contests. Dick Orkin's infamous "Chicken Man" a radio series and "The Tooth Fairy" another radio series episodes were heard daily.

For many years, KSTT remained the top-rated station in the Quad Cities market. But by the late 1970s and early 1980s, KSTT's audience started to shrink. In August 1984, KSTT changed callsigns to KKZX, known to listeners as "11-KZX", and took one last-ditch effort at Top 40 music and had mild success. In early 1986, KKZX flipped to easy listening until 1987. After Guy Gannett Broadcasting sold the station as well as its sister station 97X to Goodrich Broadcasting, the station returned to its legendary KSTT call letters, but began programming oldies from the 1950s through early 1970s, airing many of the same songs it played in its heyday. It worked for a while, but the resurgence was temporary.

Beginning in January 1989, KSTT was doing some simulcasting with sister FM station WXLP. By February 1992, 1170 AM's format was largely sports talk. In March 1993, the station's call letters were switched to KJOC.
