According to the high school newspaper "The North Wind", the station broadcast with 1-Watt from 1967 to 1972. The station was the subject of a Los Angeles Times story in 1989. The antenna tower was first above the original KNHS studio located near the cafeteria. The transmitter and limiter were mounted on a shelf in the old 3-room radio studio, which included an announcer's booth, a control room with a Gates audio console, and a storage room for vinyl records. The facility survived the 1971 San Fernando earthquake. In 1972 the KNHS studios and equipment were moved to the second floor of the Industrial Arts Building.
