also agreed to this arrangement but later, the station's top 40 demise halted the STL connection and all programming came out of the local Mexican studios after that. XEROK continued for a few years with immense popularity in El Paso, and much of the Southwest, but was eventually overtaken by an FM top 40 station (KINT-FM 97.5), as pop music listeners migrated to the FM band during the second half of the 1970s. In 1982, the station began a full-time, Spanish-language format as "Radio Cañón", the name the station still uses today. Operation The station usually operated with 50,000 watts days (extra power was more or less wasted by day, as the ground wave could not be pushed far enough to reach more population. By night, the skywave transmission was helped by extra power sometimes to as high as 150,000 watts. The Bill Branch-built transmitter was used until 1971, when a CCA transmitter was installed. It was also the cause of Branch's death in 1946, when he received a fatal shock while working on it. Later they got a Continental Electronics 150 kW unit. The Continental required a couple of minutes to change from low to high power settings, and the manual operation of switches in the front and the back. The station now uses a 50 kW Harris DX-50. Its base of operation and studios in El Paso were at 2100 Trawood, now the location of Grupo Radio Centro's El Paso operations (namely XHTO-FM). There is open feed line out to the tower.
