"Golden Age of Radio." In March 1941, under the provisions of the North American Regional Broadcasting Agreement (NARBA), stations transmitting on 890 kHz were moved to 920 kHz, where WGST and its successors have been ever since. During the 1940s, the studios and offices were located in the Forsyth Building in Downtown Atlanta. For many years the antenna was old-fashioned design using multi-strand horizontal wires, strung between two supporting towers on the Forsyth Building, across from Georgia Tech's campus. In the late 1940s, WGST lost its CBS affiliation to WAGA (590 AM); WGST joined the Mutual Broadcasting System and later became an ABC Radio affiliate in the 1950s. WGST was the first station to play rock 'n roll in Atlanta in the 1950s. Radio personality Paul Drew made his debut on WGST with a weekend show "The Big Record." Ray Charles' song "I Got a Woman" was recorded at WGST in the early 1950s. In 1956, WGST moved next to the Alexander Memorial Coliseum on the Georgia Tech campus. The station's facilities were built on top of the Coliseum's locker rooms, featuring two large studios for live performances, complete with grand pianos. They remained in use by WGST into the 1970s; starting in 1977, Georgia Tech's FM radio station, WREK, occupied most of the original studios, including one of the two big rooms, until 2004 when WREK moved to the current studios in the Georgia Tech Student Center. Through most of the 1960s, WGST ran a Top 40 radio format, but by the late 1960s it changed to middle of the road music, in an attempt to cut into WSB's audience. In 1971, WGST switched back to Top 40, and was billed simply as "92". By 1972, the station had changed to a Solid Gold Oldies format. In 1973, it adopted a mix of oldies and adult contemporary music. The station did fairly well in the Arbitron ratings (now Nielsen Audio), but it was stronger at night, particularly in the male 25-49 demographic, boosted in part when WGST became the flagship station for the Atlanta Flames hockey broadcasts. The station continued with its long-running Georgia Tech Football Network and Georgia Tech Basketball broadcasts. As the city kept growing, it was difficult to hear the station in some of Atlanta's suburbs. That made it hard to achieve numbers comparable to ratings king WSB, which is powered at 50,000 watts around the
