KRTU 91.7 FM is Trinity's FCC-licensed, professional radio station, broadcasting since 1976. It is noncommercial and listener supported, with formats that include: jazz and indie/alternative rock.  All formats are programmed, hosted and managed by Trinity University students under supervision of KRTU's professional staff.

The station offers an exciting opportunity for students to become involved in professional broadcasting. One-hour apprenticeships courses in radio hosting, production, development, and management help students learn what it takes to work for and manage a professional media outlet. Interested and committed students also may explore opportunities for internships and paid management positions.

In 2007, KRTU joined the first wave of radio stations in the country to begin broadcasting in HD digital audio. The conversion to the new format was made possible through a technology grant provided by the AT&T Foundation. What started as a strictly volunteer lab is now a highly-active media outlet that ties professional staff with community volunteers and students working as interns, managers and on-air hosts.

KRTU broadcasts are available across the San Antonio area in high definition and worldwide via the Web. Popular shows include "The Blue Note Hour," "The Latin Jazz Brunch," "The Jazz Voice," "The Diggin' Deep Soul Shakedown" and "The Blues Review."
