WCAL-FM started as a pirate too.
The Vulcan Radio Club was formed in the mid-1960s, but it split within a couple of years between those interested in AM/FM broadcasting and amateur, or “ham,” radio operators
In spring 1969, students attempted to set up an unlicensed station in Vulcan Lounge, according to the Cal Times.
The station – now called WMCL – moved first to McCloskey Hall, then to a student's basement, then to a house on Beazel Street where train whistles interrupted the programs.
Finally, in fall 1971, the radio station moved to the basement of the student center, and the Student Activities Association requested a 10-watt FM license from the Federal Communications Commission.
Permission was granted in 1972. An official station – the 10-watt WVCS (Voice of Cal State) – was finally on the air, operated by the Student Broadcast Club.
