The station was housed in the Main Building of the campus and broadcast from 1950 to 1969.[2] The frequency was later reassigned to the newly-established Radyo Veritas as its inaugural frequency, prior to the realignment of AM broadcast frequencies under the 9kHz spacing rule.
Tiger Media Network (TMN) was established in 2018 by the university's Communications Bureau, serving as the successor of DZST.
TMN focuses on production and distribution of content by and for the Thomasian community. The network is operated by student volunteers who are passionate about multimedia storytelling, providing a platform for future media professionals to develop their skills.
TMN operates two main stations serving the entire campus: Tiger TV and Tiger Radio. TMN would later become its own entity as the Tomasian Cable Television (TOMCAT).
Tiger Radio was established in the late 2000s; it would later become part of TMN upon the 2018 formation. It serves as the official campus station of the UST community, which was formerly served by the defunct DZST.
UST Tiger Radio originates from the Educational Technology Center on the 12th floor of the Buenaventura Garcia Paredes, O.P. building within the university campus. The station operates online via web streaming from Monday to Friday, except during semester breaks.
