The station began life in 1983 with the KRRZ call sign, broadcasting at 6,000 watts, with an adult contemporary format as "Magic 102".

In 2000, Clear Channel Communications bought Ingstad's stations, and changed the moniker to "K102", with a similar logo to co-owned "K102" (KEEY) in Minneapolis, Minnesota.

In 2005, the syndicated The Bob & Tom Show replaced Robbie and Dave, and the format was adjusted to all-'80s hits.

On February 10, 2007, The Box tweaked to a mainstream rock "on shuffle", as a stunt, and changed its call sign to KRWK.

The former lineup included Tom Becka in the morning, Kilmead & Friends, Rush Limbaugh, Sean Hannity, JD Hayworth, and others.

[5] On September 12, 2017, at midnight, after playing "One Way or Another" by Blondie, KRWK flipped to variety hits as "101.9 Jack FM".
