WSTU went on the air in December 1954.  Les Combs was the original owner.  In 1969 the station was sold to Harvey L Glascock, whose family owned the station until 1997 when it was sold to American Radio.  After a brief ownership by a Broward County businessman, it was sold to Barry Grant Marsh and David Pomerance.  Marsh had been Operations Manager of WSTU for many years under the Glasscock family.

When WSTU went on the air, Stuart went from the biggest city on Florida's east coast without its own radio station to the smallest city on Florida's east coast with its own radio station.

Teter has won many awards for news excellence from UPI and AP including Best Newscast in Florida and Best Spot News Reporting.  From the earliest days the Martin County community viewed the station as more of a public utility than a privately owned radio station.  WSTU was also one of the first radio stations in Florida to broadcast high school sports on a regular basis and continues to broadcast high school football, basketball and baseball.  Hamp Elliot did the play-by-play for many years followed by Teter who handled the play-by-play for more than 20 years.  Rick McGuire now does much of the play-by-play.
