KKWF

Country music radio station in Seattle

As network programming moved from radio to television, KIRO AM FM switched to a full service middle of the road format of pop music, news and sports. In 1963, Queen City Broadcasting, owned by Saul Haas, was sold to Bonneville International, a broadcasting corporation set up by the Church of Jesus Christ of Latter day Saints (LDS Church).

In the late 1960s, the Federal Communications Commission (FCC) began requiring FM stations in large cities to stop full time simulcasts of their co owned AM stations. For a few years, KIRO FM aired a progressive rock format, beginning in 1967.

The station flipped to Beautiful Music in 1973, utilizing the WRFM (New York City) program service, which was later renamed the Bonneville Program Services. In 1974, the KIRO FM call sign was changed to KSEA to separate the FM station's identity from the AM. At the time, KSEA competed against KEUT, KEZX, KBIQ and KIXI, all of which aired easy music formats. The format gradually evolved from mostly instrumental beautiful music to a mix of instrumentals and vocals as easy listening ("Easy 101") in the early 1980s. In the mid 1980s, as the easy listening audience was aging, KSEA moved to soft adult contemporary music.

On February 17, 1989, KSEA shifted to a mainstream adult contemporary format. KSEA also telecasted its audio on KIRO TV throughout the late 1980s into the early 1990s when KIRO was off air, mainly during sign off time in overnights. The station shifted to hot adult contemporary as KWMX ("Mix 101") in April 1991, though this would last for only a short time.

On September 21, 1992, the station returned to a simulcast of then sister station KIRO. With the change, the KIRO FM call letters were reinstated. From February to September 1993, KIRO FM was promoted as being part of the "KIRO News Network", with KIRO's radio and TV personalities working together as part of an experiment dubbed "News Outside the Box". The station broke the simulcast (except for mornings) on July 5, 1994, airing a separately programmed talk format, while retaining the KIRO FM call sign. The initial lineup included a simulcast of KIRO in morning drive time (which would be replaced by local comedian Pat Cashman in September), Rick Enloe in late mornings (who would later be replaced by Amy Alpine), Dave Brenner and Dr. Laura Schlessinger's syndicated show in afternoons, Gil Gross (syndicated from San Francisco) in evenings), Leslie Marshall at night (who would later be replaced by Jim Bohannon), along with Bernie Ward and David Essel on weekends.

On January 6, 1995, the station rebranded as "100.7 The Buzz," and added the syndicated Tom Leykis Show to the lineup. KIRO FM was sold by Bonneville to Entercom in March 1997. The station changed its call letters to KQBZ in May 1999, and shifted to hot talk in 2000 with the slogan "Radio For Guys." During the early 2000s, KQBZ carried Don & Mike in middays and Phil Hendrie in evenings. By November 2005, the station's weekday lineup consisted of local personalities Robin & Maynard (who were previously on KZOK FM) in mornings, BJ Shea in middays, Tom Leykis in afternoons, The Mens Room in evenings, and John and Jeff and All Comedy Radio in late nights, with paid and specialty programming on weekends.

At 8 a. m. on November 30, 2005, in the middle of "Robin & Maynard", the station began stunting with a countdown clock (using Microsoft Sam) to Noon the same day. At that time, the station flipped to country as "100.7 The Wolf" with the new call letters KKWF. The first song played on The Wolf was "How Do You Like Me Now?!" by Toby Keith. With the flip, The Men's Room and BJ Shea moved over to sister station KISW. Tom Leykis moved over as well, but on tape delay, from 11 p. m. to 2 a. m.

Entercom acquired KKWF's long time country rival KMPS in November 2017, as a result of its merger with CBS Radio. In the immediate aftermath of the merger's completion, KMPS dropped its country format in defense of KKWF (making it the only full market country station in the Seattle market), and ultimately flipped to soft adult contemporary on December 4, 2017. Rock station KVRQ would flip to country later the same day.

KKWF signed on HD Radio operations in 2006. 100.7 HD 2 carried a comedy radio format simply branded as "All Comedy Radio." The format had been heard overnights when the station was KQBZ. On June 18, 2011, the signal flipped to Smooth Jazz, filling the void left open by KWJZ when that station flipped to Modern AC on December 27, 2010. In late February 2012, the Blues format from sister station 103.7 HD2 was bumped to 100.7 HD2, effectively ending the smooth jazz format. In early June 2018, 100.7 HD2 and 94.1 HD2 swapped formats, with the blues format moving to 94.1 HD2 and the classic country format moving to 100.7 HD2.
