Troy University Public Radio

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 NPR news and classical music, combined with an automated block of "beautiful music" between 9:00 a.m. and 4:00 p.m. TUPR discontinued the easy-listening daytime format in 1993 in favor of then-more conventional classical programming.

The station would expand its service area to all of southeastern Alabama in the 1980s, adding the frequencies in Columbus in 1984 and Dothan in 1986.

Public Radio is one component of Troy University's Broadcast and Digital Network; the other is "TrojanVision", a student-operated television channel seen on several cable systems throughout southeastern Alabama.

HD-2 consists of the all-music Classical 24 network, while HD-3 airs news programs from the BBC World Service.
