History of 1170 kHz
The station signed on in July 1946, but it wasn't until the mid-1950s—when it began playing the then-new Top 40/contemporary hit radio 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-City area servicemen in Vietnam had tapes of KSTT programming sent to them.
The station, which was located along 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, Mark Stevens, Lou Gutenberger, Bobby Rich, Ruth and Fred, Spike 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 Directors Jerry Reid, Dave Douglas (Tom Hosmanek) and Gary Hummel.
"KSTT listeners became participants as well as listeners, calling Ruth and Fred on the Phone Show, phoning in news tips, (and) requesting songs," one history of the station stated. "They attended KSTT-sponsored hootenannys and hops, ball games and picnics, concerts and Good Guy-A-Go-Go dances. And they entered contests." Dick Orkins infamous Chickenman and Toothfairy episodes were heard daily.
For many years, KSTT remained the top-rated station in the Quad Cities market. But by the late 1970s, with FM radio stations gaining in popularity (particularly KIIK 104), KSTT's audience started to shrink. In the mid-1980s (1984) KSTT changed its call letters to KKZX, known to listeners as 11KZX and took one last-ditch effort at "Top 40" music and had mild success, that lasted until early 1986. 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 Golden Oldies -- music from the 1950s through early 1970s. It worked for a while, but the resurgence was temporary.
Recent history: From sports to talk to oldies to sports again
Beginning in January 1989, KSTT was doing some simulcasting with its sister FM station, WXLP (aka 97X, a rock-oriented station). By February 1992, 1170 AM's format was largely sports and sports talk, and in March 1993, the station's call letters were switched to reflect its format: KJOC.
During its 10-year run as a sports station, KJOC received most of its programming from ESPN Radio, and was the Quad-Cities outlet for Chicago-area professional sports—including the Bears, Bulls, Cubs and White Sox. For most of the 1990s, KJOC also provided coverage of local sports.
In April 2003, KJOC adopted a talk radio format. Branding itself, "Super Talk 1170," KJOC's flagship program was "The O'Reilly Factor" hosted by Bill O'Reilly. Chicago-area sports remained a fixure on the station.
On August 20, 2008, KJOC switched to an oldies format, getting most of its programming from ABC Radio Networks' "True Oldies Channel." The sports lineup continued to feature Chicago-area and Iowa State University sports.
On February 20, 2012; the station "KUUL 101.3" KUUL switched to a Top-40 from their oldies format, which temporarily left KJOC as the lone oldies station in the Quad Cities; shortly after KUUL's switch, WYEC-FM ("Rewind 93.9") began emphasizing its oldies format, which it had adopted some time earlier. KJOC's "True Oldies Channel" service focused on 1960s and 1970s music, while WYEC largely played music from the 1970s and 1980s plus some from the 1960s.
On August 30, 2013, a deal was announced in which Townsquare Media would acquire 53 Cumulus Media stations, including KJOC, 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 transaction was consummated effective November 14, 2013.
Starting on June 16, 2014, sister station KQCS (93.5 FM) began simulcasting KJOC's AM signal, as part of a planned format change – from hot adult contemporary to sports – at that frequency. The duplication is expected to remain in place until sometime in the fall of 2014, when KJOC will make an as-of-yet-undetermined format change. At that time, Iowa State University sports and Chicago Cubs baseball – which has remained at 1170 AM through the recent format switches – were expected to move to 93.5 FM.
On July 1, 2014, KJOC changed its call letters to KBOB.
