KSLG-FM launched on May 1, 2001, three years after Lost Coast Communications secured the license from the FCC. Lost Coast Communications paid another radio operator, Eureka Broadcasting, US$70,000 to withdraw a bid for the 94.1 Frequency, then had to secure investors to begin operating.
In 2013 the station shifted from playing a mix of current and dated Modern rock to mostly new Independent music and Alternative rock with a majority of the playlist only dating back a few years. The playlist features some more recognizable artists, listener submissions, artists with smaller followings, non-singles, deep cuts and artists with little to no money behind them. Morning personality and Music Director Myles Cochrane currently hosts a three-song countdown at noon at 5 p.m. weekdays featuring potential adds from a rotation of lists, charts, submissions, personal finds and archived material.
