About KZSM True Community Radio
Listener Supported, Volunteer Powered
A Non-Commercial FM Radio & Online Streaming Station
KZSM's mission is to engage, enlighten and communicate the rich diversity of our South Central Texas community. The KZSM schedule includes both locally produced and award-winning national programs.
KZSM is authorized by the Federal Communications Commission to broadcast at 104.1 MHz from our tower at the Square. We are required to move to a new tower. Your donation is urgently needed to help us complete the move, raise transmission power and stay on the air.
We are always looking for board members, show hosts and fans – and local supporters whom we acknowledge on the air. Become a volunteer! To contribute music, see our Music Submission Policy.

Power the Tower FAQ
We share the 104.1 MHz frequency with a station in Wimberley. The Federal Communications Commission directs that KZSM be at least 15 miles away from that station. The move will give us full authorized power and a regular license instead of a temporary permit.
Only the transmitter and antenna will move. Our studio will stay at 216 N. Guadalupe.
Yes! The FM relocation will not affect our audio stream.
High-power stations in Houston and San Antonio can override the KZSM radio signal, especially in the mornings, due to current solar and atmospheric conditions. Broadcasting at full power from the new tower will help reduce this interference. The stream is not affected.
Given our proximity to Austin and San Antonio, 104.1 is the only available frequency for us.
The new tower has emergency power. KZSM will also retain its existing transmitter and antenna for emergency use. If utilities are interrupted at the new tower, we will be able to broadcast from downtown.
Yes! KZSM is licensed to the San Marcos Texas Community Radio Association, a 501(c)(3) non-profit corporation supported by the generosity of the community we serve.
No.
No, we are ad-free. We are allowed to acknowledge our donors on the air.
