KZSM 104.1 is transmitting from a new tower as directed by the Federal Communications Commission. We have received a full broadcast license to replace our temporary permit. The KZSM studio remains at 216 N. Guadalupe. Come visit! Our web stream continues online at this link.
Thank You to everyone who made these upgrades possible. If you made a donation, bought a KZSM T-shirt, event ticket, or even a pizza slice at our shows, you helped power the tower! KZSM especially thanks VTX1 Internet and American Red Cross, Central & South Texas Region for their support.
Our 104.1 signal now covers greater distances than ever before. We still share the crowded Texas airwaves with other stations to the north, south and west. Your radio location and antenna orientation can affect reception. If you listen in the car, small changes in your car’s position can improve reception.
See Shows for details of the local and national programs you hear on KZSM. To submit music for airplay, see our Music Submission Policy.
