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, the latter of which is branded as "Route 650") and is known as the home of the Grand Ole Opry, the world's longest running radio program. The station is owned Ryman Hospitality Properties, Inc. WSM currently operates out of the Gaylord Opryland Resort & Convention Center, and visitors to the hotel may look into the studio 24 hours a day, provided the curtains are open, which they usually are.

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.

WSM reaches a worldwide audience via its Internet simulcast. It is the National Primary Entry Point (PEP) for the Emergency Alert System (EAS) in Middle Tennessee and the southwestern portion of Indiana.
