History

WTSU started broadcasting on March 1, 1977, as the state's third public radio station (the callsign stands for the university's name then, "Troy State University,"^[5] a part of the Alabama higher education system), and the first south of Birmingham. The station was assigned the call sign "WTSU" by the Federal Communications Commission (FCC).^[6] WTSU originally broadcast at 90.1 MHz with a power of 50,000 watts; by 1981, it moved to its present frequency of 89.9, doubling its wattage to 100,000. Programming from the start was a blend of news and classical music, combined with an automated block of "beautiful music" between 9:00 a.m. and 4:00 p.m. Troy University Public Radio discontinued the easy-listening daytime format in 1993.
