|Callsign meaning||"Portland-Glenn West"|
Glenn West, a local electronic engineer, founded WPGW (AM) in 1951. He and his wife owned and operated the station until 1974. WPGW-FM was granted to West as a construction permit by the Federal Communications Commission (FCC) in 1973 but was put up for sale due to West's advancing age and health concerns. Both stations were sold in the summer of 1974 to Bob Brandon (previously with WOWO in Fort Wayne).
WPGW-FM made its debut one year later on May 19, 1975. Both stations remain owned and operated by its company and licensee WPGW Inc.
In 1980, Rob Weaver purchased WPGW Inc. and both stations from Bob Brandon.
