Third Annual San Marcos Music Awards

The Third Annual San Marcos Music Awards take place January 30, 2026, at the historic Price Center in downtown San Marcos, and KZSM needs your input to make it a celebration to remember.


KZSM is the voice of San Marcos, so we need YOU, our SMMA Members to nominate and vote for your local favorites.


You must be a SMMA member to nominate or to vote in the First Round. See our Events page to join or renew your membership and vote!

San Marcos Music Awards Sponsorships

Support Community Radio in San Marcos! Become a corporate sponsor and get a front row seat to the Second Annual Red Carpet event. The Price Center will again host this signaure event. Choose a level of donation to the Non-Profit 501(c)3 San Marcos Texas Community Radio Association that can work as an end of year donation. See information at this link.

You Can Help Power the Tower!

KZSM 104.1 must move our transmitter and antenna from Guadalupe Street to a new tower. You can help! A $20 donation gets you an I Powered the Tower sticker; $50.00+ gets a T-shirt. But any amount will be gratefully accepted!


Your tax-deductible contribution lifts up the culture of San Marcos as expressed by KZSM music and public-affairs programming. In addition it will support the city's emergency communications preparedness.

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.
