KNWZ
KNWZ debuted at 1270 AM in 1988 under the ownership of William Hart. It was the area's second attempt at an all-news format in the style of KNX, the all-news station in Los Angeles. But soon it was converted to a talk radio format. Jerry Jolstead had sold the station and Hart purchased it from Mary and Kate Neiswender. The morning drive slot was occupied from 1994-2000 by Luigi Rossetti under the air name of "Lou Penrose." Rossetti left the station at the height of his popularity to accept a position as District Director for Congresswoman Mary Bono. The Lou Penrose Morning Talk Show was followed from 9-11a.m. by former television newsman Ron Fortner. Fortner was let go in 1998, immediately after the purchase of the station by Morris Communications as part of the new Desert Radio Group.
The station had been simulcast on two FM repeaters and one other station (94.3, 103.9 and 106.9) from April 1995 to October 1998, when Morris purchased the stations; it then converted all three of the FM stations to music formats. Morris then moved KNWZ to 970/1140AM on January 1, 2001.
In October 2009, K-News began to operate an FM radio translator on 94.3 MHz from Desert Hot Springs covering the Coachella Valley. In 2016, KNWZ began to be heard on 103.7 in the Twentynine Palms area. In 2018, it added a translator on 104.7 FM for the Palm Springs area, in addition to 94.3 FM from Coachella.
Morris sold the three stations, along with thirty others, to Alpha Media LLC for $38.25 million, effective September 1, 2015.
