Alternative rock era as "Alt 105.3"
On August 29, 2014, at 9 a.m., after playing "Movin' Out (Anthony's Song)" by Billy Joel, KCOF dropped it's oldies format and began stunting with a "wheel of formats" - consisting of (among other formats) all-Grateful Dead, all-Van Halen, all-Journey, adult contemporary, all-Backstreet Boys, contemporary Christian music, all-dream pop, outlaw country, urban contemporary, Spanish pop music, beautiful music, all-glam metal, and all-indie rock - branded as "The 105.3 Wheel of Formats", with each new format starting every few hours each day. The station's website allowed listeners to vote for which format was their favorite.

On September 12, 2014 at 5 p.m., KCOF settled on a permanent format, alternative rock, as "Alt 105.3". The new format was intended to compete with the market's then-only alternative rock station, KVKZ (owned by ). Despite a promise to "beat the Z", the station's new format lagged in the local listenership ratings behind KVKZ, and the station had a high turnover of local staff.

Many Kansas City media observers regarded "Alt 105.3" as a failure, and by then it was decided that a change had to come.

Flip to '80s hits
On June 1, 2016, after playing "1985" by Bowling for Soup and "Bingo" by Catch (the latter of which abruptly faded out in the same spot wherein a broadcast of it's music video was interrupted by Britain's ITV for news on the death of Diana, Princess of Wales), KCOF officially dropped it's "Alt 105.3" format and began stunting with a four-song loop of "The Power of Love" by Huey Lewis and the News, "Run With Us" by Lisa Lougheed, "I Wanna Rock" by Twisted Sister, and "Take on Me" by A-ha, which was mixed with on-air announcements stating "the time has come for something new" along with sweepers telling listeners to tune in on June 5th at 5:00 p.m. for "a bodacious blast to the past." On June 5 at 4:30 p.m., the stunting shifted to a 30-minute montage of soundbites from various 80s movies and TV shows and brief snippets from various 80s songs.

Then, at 5:00 p.m. as promised, a pre-recorded station identification was played followed by a short introduction of the new all-80s "105.3 KCOF" format by the station's new voiceover artist Mitch Craig, which was then followed by pre-recorded greetings from several 80s celebrities and music artists such as and. Then, at exactly 6:30 p.m., the legally mandated station identification played again, and KCOF-FM's all-80s format officially started with "Back in Time" by Huey Lewis and the News. The relaunch included nearly 2,000 songs played commercial free. Former DJ K.J. Petrazzuolo became the host of KCOF-FM's new morning show Blast to the Past with K.J. Petrazzuolo effective July 1, 2016.

In 2018, iHeartMedia hired Chuck K. Redner as program director, replacing Hiro Nobumoto (who was transferred to sister station KMCI-FM).

Currently on weekdays, the station has K.J. Petrazzuolo in morning drive, with Mavis Browning (who is voice-tracked from ) in afternoon drive and Antwone Sanchez hosting an evening requests show.

HD2
In February 2014, KCOF-HD2 was activated and began broadcasting a country format, 91.7 The Bull, simulcast on a newly signed-on translator of HD2, K219CB. This format grew to be a failure in the ratings compared to the dominant. (iHeartMedia would have a second, more successful attempt at a country-formatted station when the iHeartMedia-operated KASQ flipped to country in late-2018, also under the "Bull" branding, as KCBL-FM 102.7 The Bull).

Concurrent with KCOF-FM's flip to 80s hits, KCOF-HD2/K219CB flipped to 90s hits as "91.7 KCB". On June 13, 2016 at 5:00 p.m., after playing a montage of country songs either with "goodbye" or "change" in the title or overall theme (ending with "Leaving Las Vegas" by Sheryl Crow), the station went into a five-minute long introductory montage, culminating with the launch of "91.7 KCB" at 6:02 p.m., with "No Scrubs" by TLC being the first song played.
