KTSL (101.9 FM) is an Air1 network affiliate radio station broadcasting a Christian worship format.

Licensed to Medical Lake, Washington, the station serves the Spokane metropolitan area.

In 1991, it moved to 101.9 MHz, initially called "The Word In Music" and later "Power 101.9", to reflect its Christian rock sound.

As of May 2008, KTSL is broadcasting the Air 1 Radio Network, an adult contemporary format playing well established songs combined with worship music.

The KTSL call letters were once used on channel 2 in Los Angeles, now KCBS-TV.
