The radio studios and offices are in Seattle's Belltown neighborhood northwest of downtown.

It was owned until 1963 by Rogan Jones, founder of the radio automation firm IGM.

In 1967, it was sold to Elroy McCaw, the owner of KIXI (880 AM), who kept the beautiful music format as a simulcast of the AM station.

In 1970, Wally Neskog bought the stations, and changed KGMJ's call letters to KIXI-FM on October 19, 1978.

On April 28, 1986, it changed call letters and monikers to KLTX "95.7 K-Lite", airing a soft adult contemporary format.

[5][6] After three weeks of stunting with a mix of music ranging from 1980s' pop, grunge rock, rap, all-'60s music, country, and hot adult contemporary (and branded as "The Northwest's New 95.7", a nod to KUBE's early years in the 1980s), the station's format was changed to all 1970s hits on April 29, 1994, and changed call letters to KJR-FM on June 1.

[10] In early 2000, the station gradually added more 1980s and 1990s music, while still keeping the KJR-FM call letters.

However, with the nationwide decline with the rhythmic oldies format, the station fell in the ratings as well.

[14][15] On May 31, at 5 p.m., the stunting concluded and during a live broadcast from the Space Needle, the station changed formats back to classic hits as "Superhits 95.7 KJR-FM" and changed call letters back to KJR-FM a month later.

It hired one of the legendary DJs from the original KJR AM in the 1970's, Ric Hansen, to be its morning personality.

In 2008, KJR-FM started rebroadcasting classic American Top 40 shows from the 1970s, picking up the rights from KBSG, which had changed formats that year.

Over the last two months of 2013 and into 2014, KJR-FM altered its format to add more classic rock and grunge artists.

[21] On August 8, at 10:08 a.m., following Bob Rivers' goodbye show, KJR-FM flipped back to classic hits and rebranded as 95.7 The Jet.
