KFBW (105.9 MHz) is a commercial FM radio station licensed to Vancouver, Washington, and broadcasting to the Portland metropolitan area. Owned by iHeartMedia, Inc., the station airs a mainstream rock radio format with emphasis on the late 1970s, 1980s, 1990s and early 2000s, branded as "105.9 The Brew". The transmitter is located in Portland's west hills and the studios are in Tigard, Oregon. History The station was initially licensed to the Cincinnati-based Citicasters as of February 1996, when that broadcasting group was acquired by Jacor Communications. The station has had seven call signs since mid-1998. While owned by Jacor, it changed call letters to KXMX. When Jacor sold it to Clear Channel Communications, the call letters changed to KKLQ. In August 2000, it switched its call letters to KBET. The station officially signed on air with a modern adult contemporary music format branded as "Star 105.9" on February 5, 2001; to match the format, the call letters changed to KSTE-FM. It is also noted that the station used the same logo and slogan as Los Angeles station KYSR. At that time, both stations aired a Modern AC format. On June 21, 2002, KSTE-FM dropped the modern adult contemporary music format, likely due to lackluster ratings and direct competition from cross-town KRSK, which aired a similar modern adult contemporary music format. KSTE-FM then began stunting with short clips of almost all music genres branded as "Quick 106" (this stunt was used earlier in the year on KJR in Seattle). On June 25, 2002, KSTE-FM adopted a classic hits music format branded as "The River". A change of call letters followed on June 28, 2002 to KRVO to better match "The River" branding. On November 4, 2005, KRVO changed formats yet again, adopting the smooth jazz music format that the Portland metropolitan area was lacking since the demise of KKJZ (now KLTH) on February 1, 2002. A change of call letters to KIJZ was made to match the name of the format and new branding as "Smooth Jazz 105.9", a format now heard on sister station KKCW's HD2 subchannel. On August 30, 2007, KIJZ changed their format back to classic hits, with the slogan "Kool 105.9" and changed their call letters to KQOL on September 5, 2007. The music, originally heavy on music from the 1970s and early 1980s, was shifted in spring 2008 to more of an evenly 60s/70s based format.
