WSM is the callsign of a 50,000 watt AM radio station located in Nashville, Tennessee. Operating at 650 kHz, its clear channel signal can reach much of North America and various countries, especially late at night.
WSM’s unusual diamond-shaped antenna is visible from Interstate 65 just south of Nashville (in Brentwood) and is one of the area’s landmarks. When the 878-foot tower was built in 1932, it was the tallest antenna in North America.
WSM fIrst signed on in 1925. It is primarily associated with the popularization of country music through its weekly Saturday night program, the Grand Ole Opry, the longest-running radio program in history, although clearly they were happy to bring folks the glamour of Hollywood as well.
