WCTA (810 AM) is an American radio station licensed to serve Alamo, the county seat of Crockett County, Tennessee. WCTA is a class D facility licensed to broadcast with 250 watts of power on a frequency of 810 kHz, operating only during daylight hours to protect both KGO in San Francisco, California, and WGY in Schenectady, New York, from skywave interference. The WCTA broadcast license is held by Robert Davis, through licensee Alamo Media LLC. The station, established in 1983, fell silent on and off from 2008 through June 2012 before resuming normal operation.
