KFBW (105.9 FM) is a commercial 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 station was initially licensed to the Cincinnati-based Citicasters[2] as of February 1996, when that broadcasting group was acquired by Jacor Communications.

When Jacor sold it to Clear Channel Communications, the call letters changed to KKLQ.

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.

As of 2011, it began to expand its library to include tracks from the late 1960s, 1970s and early 1990s, along with the new slogan "Next Generation of Classic Rock" to reflect the adjustment.
