KOAS (105.7 FM, "Old School 105-7") is a radio station broadcasting a Rhythmic adult contemporary format. Licensed to Dolan Springs, Arizona, USA, 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.


  • KOAS operates an FM booster transmitter on 105.7 in Henderson, Nevada. The booster, known as KOAS-1,[2] carries 2,500 watts ERP. It provides the Las Vegas area with a stronger signal than the main transmitter located in Dolan Springs.
Radio stations KOAS(FM)105.7 and KVGS(FM)107.9 have on-channel FM boosters broadcasting from an antenna at the top of The Stratosphere. Licensed as KOAS-FM1 and KVGS-FM1, they are the only radio stations with transmitters at the tower. However, the signals being transmitted from this structure are relatively low-power and only cover the immediate Las Vegas area on a "fill in" or "booster" basis. Both of these stations have their main transmitter sites located elsewhere, and those transmitter sites are what give these stations more wide spread, regional coverage.[3][4]


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 and on August 14, 2001 the current KOAS.[6] On December 26, 2009, KOAS dropped New AC (NAC)/Smooth Jazz for Rhythmic AC, forcing KPLV to move to top 40 from rhythmic AC. On April 1, 2013, KOAS shifted their format to rhythmic oldies. In November of 2013, the long time "Oasis" moniker (from the previous smooth jazz format) was dropped in favor of "Old School 105-7".
