The station signed on the air on September 18, 1984. The original call sign was WNUY.
On May 1, 1986, the station changed its call sign to WPGS.[3]
In 1998 the station served as a critical news center for residents during the fires which claimed many homes and lives nearby. Normally a daytime-only station, WPGS stayed on throughout the danger with the owner at one point climbing the tower to see how close the fires were getting to the community.[4]
In October 2009, WPGS dropped the Talkstar radio network to become part of the Smooth Jazz "Groove Network."
