[2][3] The station is owned by the Educational Media Foundation, and airs programming from EMF's nationally syndicated "Air1" radio format featuring Christian Worship Music.

In August 1993, the station signed on as KARP, playing a wide mix of classic rock, oldies, country music and farm reports.

[4] In February 2000, KARP was purchased by a group consisting of local investors Kandu Communications and Cincinnati, Ohio-based Blue Chip Broadcasting, with the aim of bringing a full-power quasi-urban-formatted music FM station to Minnesota for the first time.

Following KARP's departure from 96.3 FM, the station began stunting, repeating a short list of songs from Twin Cities artists Prince, Morris Day, The Time, and Alexander O'Neal.

[9] On June 14, 2007, Northern Lights Broadcasting, owned by the family of Minnesota Twins owner Carl Pohlad, announced the purchase of KTTB from Radio One for $28 million (USD).

"[15] At Midnight on January 1 (after "In Paris" by Jay-Z and Kanye West), the station officially flipped to the new format, with "Misery" by Minneapolis band Soul Asylum being the first song being played, followed by "Beautiful Day" by U2 and "Learn to Fly" by Foo Fighters.

The "K-Twin" playlist featured, according to Northern Lights' preview of the change, "today’s guitar based, pop alternative music" and similar, gold-based hits from 1985 onward.

[15] "K-Twin", though it was described as a modern adult contemporary format with an alternative rock lean, was classified as adult top 40 because of rhythmic content (such as Bruno Mars' "It Will Rain") and non-alternative classic hits (such as Def Leppard's "Pour Some Sugar on Me"), and to differ itself from Hot AC rival KSTP-FM (that station reports to the Mediabase/BDS hot AC panels).

"[15] It leaned in a much older direction versus KSTP; however, as of April 2012, the station was listed on the Nielsen BDS hot AC panel.

Another noticeable emphasis of "K-Twin" was its connections with Twin Cities listeners and its employment of local personalities, including a morning show (which debuted on January 4) that featured Tone E. Fly, a KDWB alum and a former "B96" and "96.3 Now" jock, former Miss Minnesota International contestant Danni Star who is also a former "Now" jock, and KARE news personality Eric Perkins.

[16] By October 2013, KTWN-FM transformed again, shifting away from Hot AC into more of a gold-based AAA direction with the addition of artists such as The Beatles, Neil Young, The Rolling Stones, The Who, and Led Zeppelin.

With the hybrid mix of baseball and music, the station stayed steady at a mere 1.0 share over the past three monthly ratings periods of 2014.

At Midnight on January 1, 2015, 3 years to the hour after "K-Twin" debuted, after playing a set of songs with the word "go" in the title, as well as a block of "end"-themed songs (culminating with "Closing Time" by Minneapolis band Semisonic), KTWN-FM began stunting with a Siri-like text-to-speech voice quoting various movie and pop culture quotes, as well as a countdown to 3 p.m. on January 5.

The initial lineup of airstaff included Barb Abney, Brian "BT" Turner, Jason Nagel, and the duo of Thorn and Linnea Mohn.

[21] With the Pohlads' purchase of KNOF in September 2015, KTWN-FM was speculated to move to the newly acquired frequency, in order to take advantage of a larger coverage area.

In July 2020, morning show hosts Ben Holsen and Dana Wessel were let go from KQGO due to the financial impact resulting from the COVID-19 pandemic.

96.3-HD2 carried a simulcast of KBHL in Osakis ("PraiseLive"), which was previously heard in the Twin Cities on KNOF before Go Media's acquisition of the station in 2016.
