Join KZSM for Live Music Tuesday Sept. 16, 6–9 PM at the Hays County Courthouse!

KZSM 104.1 must move our radio transmitter and antenna from their current downtown location atop Guadalupe Street to a new tower. The move will enable us to broadcast at full authorized power (100 Watts) and get a regular license instead of a temporary permit.

You can help power the tower! Join us for a live music fundraiser at the Hays County Courthouse on Tuesday, September 16, 2025 from 6–9 PM. A $20 donation gets you an I Powered the Tower sticker seen at left; $50.00 and above gets a T-shirt. But any amount will be gratefully accepted!

Your tax-deductible contribution helps support and protect the culture of San Marcos as expressed by KZSM music and public-affairs programming.

Relocation FAQ

Why do you have to move to a new tower?

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 to avoid interference.

Our current location was a temporary solution while we found a permanent tower site. Only the transmitter and antenna will move. Our storefront studio will stay at 216 N. Guadalupe.

Will you still stream online?

Yes! The FM relocation will not affect our audio stream.

Why do I sometimes hear other stations on 104.1?

High-power stations on 104.1 in Houston and San Antonio can override our 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.

Why not just pick a different frequency?

With the congested radio environment and our proximity to Austin and San Antonio, 104.1 is the best and only available frequency for us.

What happens in an emergency? Will KZSM still be able to broadcast?

The new tower is equipped with robust emergency power. In addition, KZSM will retain its existing transmitter and antenna for emergency use. If an emergency situation causes utilities to be interrupted at the new tower site, KZSM will be able to broadcast from downtown.

Does KZSM receive federal taxpayer funds from the Corporation for Public Broadcasting (CPB)?

No.

Will there be commercials on KZSM?

No. As a non-commercial radio station, we do not broadcast ads. We are allowed to acknowledge our generous donors on the air.
