It transmits from a tower 707 meters (2,320 ft) in height above average terrain (HAAT) near Issaquah, Washington, on Tiger Mountain.

The owners of KRAB originally applied to share time with KNHC, owned by the Seattle Public Schools.

[9] A week later, on August 23, at 3 p.m., the station flipped to modern rock, and changed its name and call letters to "107-7 The End," KNDD.

It was the Seattle market's fourth attempt at a modern alternative format, dating back to KZAM AM 1540 in the late 1970s (now KXPA).

[12] Within six weeks of The End's first broadcast, three albums by local artists — Ten by Pearl Jam, Nevermind by Nirvana and Badmotorfinger by Soundgarden — were released.

These albums helped come to define the sound known as grunge, and the station quickly became one of the leaders in alternative rock radio.

Shortly after KRQI's sign-on, KNDD moved back to a current-based direction, although it dumped most hard rock bands.

Scott Geiger, also known as Lazlo, of sister station KRBZ in Kansas City, was named the new program director on June 1, 2006.

[17] In November 2006, he began hosting afternoons with a simulcast of his KRBZ show, which was co-hosted by his then-wife Afentra Bandokoudis, under "The Church of Lazlo" moniker.

On August 25, both "Afentra's Big Fat Morning Buzz" and "The Church of Lazlo" returned to Kansas City on KRBZ.

Other nominees included WBCN in Boston; KROQ-FM in Los Angeles; KTBZ-FM in Houston; KITS in San Francisco; and WWDC in Washington, D.C.[23] In January 2019, KNDD's HD2 subchannel flipped from an all-Pacific Northwest bands and artists format to Entercom's "Channel Q," a talk and EDM network aimed at the LGBTQ community.

[24] Channel Q also airs on Entercom HD subchannels in Los Angeles, San Francisco, Phoenix, Sacramento and Houston.
