The transmitter site is off SW 4th Street in Moore. KOKC is a Class A clear channel station, broadcasting at the maximum power for commercial AM stations, 50,000 watts. By day, the signal is non-directional. But at night, to protect WWKB Buffalo, New York, the other Class A station on AM 1520, KOKC must use a directional antenna. With a good radio, KOKC can be heard across much of the Great Plains and Rocky Mountain states at night. It is Central Oklahoma's primary entry point station for the Emergency Alert System.
