KOXR

KOXR (910 kHz) is a commercial AM radio station licensed to Oxnard, California. It broadcasts a traditional ranchera music format featuring mariachi groups from Mexico. It is owned by Radio Lazer and calls itself "La Mexicana 102.1 y 910 AM."
By day, KOXR broadcasts at 5,000 watts. But to avoid interference to other stations on 910 AM, it reduces power at night to 1,000 watts. It uses a directional antenna at all times. The transmitter is off Southern Pacific Milling Road in Santa Paula, near the Santa Clara River. KOXR is also heard on 250 watt FM translator K271CY at 102.1 MHz in Oxnard.
History.
On June 11, 1955, the station first signed on. It was owned by the Oxnard Broadcasting Corporation. For several decades the station aired a variety format, which always included at least a few hours of Spanish-language programming each week.
In the early 1990s, KOXR began broadcasting completely in Spanish.
