KJOT first signed on in 1979 as a country music station.

In 1985, the station switched to an album-oriented rock format and rebranded as "J105" after KUUB (now KAWO) dropped the format that same year. KJOT became a classic rock station around 2003 branded as "J105: Classic Rock, That Rocks". In 2006, the station changed the slogan to "J105: Everything That Rocks".

At midnight on May 14, 2010, KJOT became a mainstream rock station branded as "Variety Rock 105.1". On November 12, 2012, KJOT began stunting with Christmas music, with a new format planned when the holiday songs ended. After Christmas, KJOT returned to classic rock, still using the "Variety Rock" branding.

Journal Communications (KJOT's owner) and E. W. Scripps Company announced on July 30, 2014, that the two companies would merge to create a new broadcast company under the E. W. Scripps Company name that will own the two companies' broadcast properties, including KJOT. The transaction was completed in 2015.

On March 27, 2017, KJOT returned to its former "J105" branding.
