KWRN

KWRN (1550 kHz) is a commercial AM radio station broadcasting a Regional Mexican format, branded as "Radio Lazer 99.5 y 1550". Licensed to Apple Valley, California, it serves the Victor Valley area and is owned by Lazer Broadcasting.

By day, KWRN is powered at 5,000 watts non-directional. But at night, because 1550 AM is a clear channel frequency, KWRN must reduce power to 500 watts to avoid interference with other stations. It also uses a directional antenna with a two-tower array after sunset. Programming is also heard on 190-watt FM translator K258DE at 99.5 MHz.

History
In 1989, a construction permit was granted by the Federal Communications Commission for a new AM station in Apple Valley at 1550 kHz. The construction permit had the call sign KITH. The station signed on the air in 1991. By the time that happened, it had the call letters KAPL. The call sign changed to KWRN in 1994, coinciding with Major Market Broadcasting's acquisition of the station.

In November 2016, translator 94.3 K232EW in Ventura was purchased from Southern California Public Radio for $40,000. On November 15, 2016, the Federal Communications Commission granted a construction permit to move K232EW from Ventura to Apple Valley and change the frequency to 99.5 MHz with an accompanying change of call letters to K258DE.
