At night, to protect other stations on 1300 AM from interference, it reduces power to 5,000 watts and uses a directional antenna with a five-tower array.
From December 1962 through the 1970s, WMAK was a top 40 contemporary hits radio station, popular with young people in Nashville.
Owner Fred Gregg, who also owned WAKY in Louisville, Kentucky, helped put WMAK into a competitive position by installing a new 5,000 watt RCA transmitter.
WMAK would sign off each night at midnight until the late 60s, when Scott Shannon became Program Director and took the station full time.
Shannon, later at WHTZ, WPLJ and WCBS-FM in New York, installed his new brand of top 40 radio excitement at the station.
