Though WJMK's previous oldies format continued to be streamed online and on the WJMK's second HD Radio subchannel, complaints about WJMK's switch were numerous. In July 2006, in a cost-cutting move by CBS Radio, the entire DJ staff of WJMK-HD2 was laid off. Shortly thereafter, 94.7 WZZN, which had recently switched to an oldies format, hired several of WJMK's former airstaff. With a format change on WCKG from hot talk to adult contemporary, Steve Dahl and Buzz Kilman moved to WJMK to host mornings on November 5, 2007. Dahl was dismissed on December 5, 2008. With the exception of Dahl and Kilman, Chicago's Jack FM had no live personalities. WJMK's ratings plummeted after the switch to Jack FM, and the station saw further ratings erosion when Bonneville International debuted "Rewind 100.3" (a mostly 1980s-based format) on rival WILV in June 2010. K-Hits On March 10, 2011, CBS Radio announced the station would return to their previous classic hits format as "104.3 K-Hits", setting the time of relaunch for the following Monday, the 14th, at 1:04 p.m.; at 12:30 that afternoon, after playing "Goodbye to You" by Scandal, the station began stunting with a montage of songs and pop culture clips from 1966 to 1989, and at the promised time, "K-Hits" was launched with "Beginnings" by, fittingly, Chicago.

Weekend hosts included Tommy Edwards, Ken Cocker, and John Calhoun. Eddie and JoBo were released on December 6, 2012, with the station citing low ratings as the main factor. Mornings were then hosted by Dave Fogel, formerly of WLS-FM. Tommy Edwards retired from radio on September 12, 2014. The rest of the station's final airstaff included Brian Peck in middays and Jeffrey T. Mason in afternoon drive. In its last year, WJMK primarily played music from the 1970s and 1980s. 104.3 Jams On February 2, 2017, CBS Radio announced it would merge with Entercom. The merger was approved on November 9, 2017, and was consummated on November 17. On November 17, at 10 a.m., after playing "The Long
