About KTSW

KTSW 89.9 is a student-run, noncommercial radio station at Texas State University in San Marcos, Texas. We have students of all majors working in a variety of departments that make KTSW a source of quality on-air and online content.

Primarily, we spin college rock, serving an eclectic mix of garage and psych-rock, indie-synth-pop thrown in the mix. Our format relies on the music flourishing in our local scene. It’s the raw, deep tracks of albums and a bit rough around the edges. Our diverse love for music expands our selection. If you’re looking for the best in up-and-coming live music in San Marcos, check out one of our three monthly showcases held during the fall and spring semesters.

Local First

Here at KTSW, we strive to serve the San Marcos community. Other Side Drive brings in local organizations for on-air interviews and local artists for in-studio performances.

Our news department keeps you up-to-date on issues affecting the San Marcos and surrounding communities, while sports reporters work closely with the San Marcos High School Rattlers to celebrate their wins, analyze their losses and visit the practices in between.
