The Syracuse radio market passed a milestone over the weekend, marking the 80th anniversary of the sign on of the area's first radio station. It was on September 15, 1922 from his estate off Route 13 in Cazenovia that Clive Meredith, for the first time, flipped the switch at station WMAC. Six years later, Meredith moved WMAC's transmitter to the top of the Hotel Syracuse and changed the station's call letters to WSYR. A shift in frequency from 1330 to 570 AM followed in 1931.
