WPGU

WPGU began in 1957 as a carrier current station heard on 640 AM.  They "broadcast" to the dorms at the University of Illinois in Champaign-Urbana.  FM transmissions began in 1967 while the carrier AM signal became WDBS.  The WPGU call letters stand for (W) Parade Ground Units which was a 21-building complex built after WWII to house students and families.  The 3000-watt station carries an Alternative/Indie Rock format.  The 1990 commercial below indicates that they were a mainstream Rock station at the time.
