WCEO (840 AM, "La Raza 840") is a Regional Mexican radio station located in Columbia, South Carolina, United States.
The station is licensed by the Federal Communications Commission (FCC) to broadcast during daytime hours only (sunrise to sunset) with a power of 50,000 watts.
840 AM originally signed on January 1, 1994, as WCTG with a Christian/Talk format using programming from USA Radio Network.
However, this arrangement lasted less than a month before the station changed again to Spanish Contemporary as "La Tremenda", reclaiming the WCEO call letters in the process.
WCEO must leave the air from sunset to sunrise to protect clear-channel WHAS in Louisville, Kentucky.
