What’s Happening

KZSM Tower Relocation Campaign

KZSM 104.1 is raising money for our new transmitter and antenna. We have to move from our current spot on Guadalupe Street by September 7, 2026, to a new tower south of San Marcos.


The move will enable us to broadcast at our full authorized power (100 Watts) and get a regular license instead of a temporary permit.


​The campaign's goal is to raise approximately $12,000 to cover new transmitting equipment, engineering fees and installation. It does not include rent or utilities at the tower. These are among KZSM's ongoing financial needs.


Your help can make this happen! Your tax-deductible contribution helps support and protect the culture of San Marcos as expressed by KZSM music and public-affairs programming.

Relocation 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 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.


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


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.


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


KZSM will retain its existing transmitter and antenna for emergency use. If utilities are interrupted at the new tower site, KZSM could receive emergency permission from the FCC to broadcast from downtown.


No.


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