WSM (AM)

WSM (650 kHz) is a commercial AM radio station, located in Nashville, Tennessee. It broadcasts a country music format (with classic country and Americana leanings) and is known as the home of the Grand Ole Opry, the world's longest running radio program. The station is owned by Opry Entertainment Group, a majority-held subsidiary of Ryman Hospitality Properties, Inc. The station broadcasts from studios adjacent to the Grand Ole Opry House. Nicknamed "The Air Castle of the South", the station broadcasts with 50,000 watts around the clock from a facility in Brentwood, Tennessee. It has one of the largest daytime coverage areas in the country, providing at least grade B coverage as far southeast as Chattanooga, as far northwest as Evansville, Indiana, as far west as Jackson, Tennessee, and as far south as Huntsville, Alabama. At night, WSM's clear channel signal reaches much of North America and nearby countries. Because of its prominence in the pantheon of country music, and its near-nightly live broadcasts of the Grand Ole Opry, the station regularly reaches a worldwide audience via its internet stream. WSM is the National Primary Entry Point (PEP) for the Emergency Alert System (EAS) in Middle Tennessee and the southwestern portion of Indiana.
