The transmitter is in Orange Cove, California, on East American Avenue at Cove Road. While AM 580 is a Regional broadcast frequency, the station is powered at 50,000 watts, the highest power for an AM station permitted by the Federal Communications Commission (FCC). To protect other stations on AM 580, KMJ uses a four-tower array directional antenna. The signal covers most of Central California and reaches into the Bay Area, Sacramento and Bakersfield. KMJ is Central California's primary entry point station in the Emergency Alert System.
