The beginning

This station began regular operation on September 18, 1978, broadcasting with 3,000 watts of effective radiated power on a frequency of 99.3 MHz.^[2] The station was assigned the call sign KOHU-FM by the Federal Communications Commission.^[1] Launched as a sister station of KOHU (1360 AM), KOHU-FM broadcast a beautiful music format under the guidance of general manager and chief engineer Harmon Springer and program director Willie Kelly and the ownership of the Hermiston Broadcasting Company.^[2]

The station was assigned new call sign KQFM-FM by the FCC on March 1, 1984.^[1] Just over two years later, on November 25, 1986, the station changed call signs again, this time to the simpler KQFM.^[1]

New ownership

In February 1997, the Hermiston Broadcasting Company reached an agreement to sell KQFM and AM sister station KOHU to the Capps Broadcast Group through their West End Radio, LLC, subsidiary.^[3] The deal was approved by the FCC on April 16, 1997, and the transaction was consummated on May 1, 1997.^[4]

Move to 100.5

In April 2000, KQFM applied to the FCC to change its assigned broadcast frequency from 99.3 MHz to 100.5 MHz.^[5] The change was made as part of a multi-station shuffle to accommodate a power increase by KUJ-FM in Burbank, Washington.^[6] The station received a new construction permit to authorize the change on August 8, 2000.^[5]

In January 2003, the Capps Family, co-owners of KQFM licensee West End Radio, LLC, announced an agreement to transfer control of the company to Ronald L. Hughes and Gloria Hughes. The deal was approved by the FCC on February 14, 2003, and the transaction was consummated on June 4, 2003.^[7] This move coincided with the station's flip from oldies to adult contemporary music.^[8] In March 2004, Ronald L. Hughes and Gloria Hughes applied to the FCC to transfer the broadcast license for KQFM to the Ronald L. Hughes and Gloria Hughes Living Trust. The transfer was approved by the FCC on April 7, 2004, and the transaction was consummated on April 12, 2004.^[9]

Move to 100.1

In April 2007, KQFM filed another application with the FCC to change its assigned broadcast frequency again, this time from 100.5 MHz to 100.1 MHz.^[10] This move is part of a multi-station shuffle involving KQFM and KWRL to allow religious broadcaster KHSS in Walla Walla, Washington, to obtain a "bigger, more powerful" signal at 100.7 MHz.^[11] The transmitter site would also be moved very slightly to the west and the antenna raised to 94 meters (308 ft) in height above average terrain. The station received a new construction permit to authorize the change on September 17, 2007.^[10] The station began licensed operation on 100.1 MHz on February 17, 2010.

Move to 93.7

On February 4, 2016 KQFM moved from 100.1 FM to 93.7 FM, swapping frequencies with KRKG-FM Pasco, Washington, which moved from 93.7 FM to 100.1 FM.^[12]
