WCSZ

WCSZ (1070 kHz, "La Jefa 94.9 FM & 1070 AM") is a commercial AM radio station licensed to Sans Souci, South Carolina, United States, and serving the Greenville–Spartanburg media market in Upstate South Carolina. WCSZ is owned by Tama Broadcasting and airs a Spanish contemporary hit radio format. The station is simulcast on FM translator W235BM at 94.9 MHz located on Paris Mountain in Travelers Rest and licensed to Mauldin, South Carolina. The station identifies itself as "La Jefa" which means "The Boss" in Spanish.

By day, WCSZ is licensed to broadcast at the maximum power allowed by the Federal Communications Commission (FCC), 50,000 watts non-directional. Because AM 1070 is a clear-channel frequency, reserved for Class A stations KNX in Los Angeles and a now-dark facility in Canada (formerly used by CBA in Moncton, New Brunswick), WCSZ must reduce power at night to 1500 watts using a directional antenna to avoid interference. The station's transmitter, a 3-tower antenna array, is off West Duncan Road (U.S. Route 25) in Greenville. WCSZ is one of 5 AM radio stations in South Carolina operating at 50,000 watts by day, the others being WESC in Greenville, WAGL in Lancaster, WBAJ in Blythewood, and WCEO in Columbia.
