KOAS (105.7 FM, Jammin' 105.7) is a radio station broadcasting an urban adult contemporary format. Licensed to Dolan Springs, Arizona, United States, the station serves the Laughlin/Las Vegas/Dolan Springs area. The station is currently owned by Beasley Broadcast Group, Inc. through licensee Beasley Media Group, LLC. The station's studios are located in the unincorporated Clark County area of Spring Valley, while its transmitter is in Dolan Springs.
The station was assigned the call sign KCRR on August 1, 1984. On November 20, 1987, the station changed its call sign to KFLG. On December 12, 2000, the station became KBYE.
On August 8, 2001, KBYE flipped to smooth jazz as "The Oasis", with the station changing call letters to the current KOAS on the 14th.[3] [4]
On December 26, 2009, after airing Christmas music for a month, KOAS dropped Smooth Jazz for Rhythmic AC, giving the market two stations in the format, the other being KPLV (which would shift to top 40 roughly four months later).
On April 1, 2013, KOAS shifted their format to rhythmic oldies. In November 2013, the long time "Oasis" moniker (from the previous smooth jazz format) was dropped in favor of "Old School 105.7".[5]
On June 17, 2019, at Midnight, KOAS flipped to urban adult contemporary as Jammin 105.7.[6] Musically, KOAS leans to Rhythmic Hot AC with hip-hop artists such as The Notorious B.I.G., Lil' Kim (and by extension Junior M.A.F.I.A.), Snoop Dogg, Eminem, Dr. Dre, and Outkast added to rotation.
