KYDS is a Sacramento, California, radio station with the frequency 91.5. It is maintained at El Camino Fundamental High School and select students from the school are allowed to participate in its operation. "KYDS"'s original inception was in 1976 where it broadcast only to the school cafeteria during lunch hour. "KYDS" originally got its FCC broadcast license in 1978 as one of the last Class "D" licensed FM stations in the country. The station went on the air with all of 10 watts of power (transmitter power output, not effective radiated power), into a 4-bay antenna and broadcast a monaural signal that effectively covered a 5-mile radius.
