The original transmitter site was located south of Comanche Peak in El Paso. A road was built to the site, and a tower was constructed. A building was assembled from the rock chipped from the site. The station went on the air with a temporary transmitter (small RCA) and eventually added a 10 kW RCA TT-10AL transmitter, broadcasting at an effective radiated power (ERP) of 61 kilowatts at . That site is now used as a backup facility for channel 4, and many local FM radio stations transmit from this building.
