In the early 1970s, KFJC was a randomly block-formatted station, playing mainly bubblegum top 40, specialty/ethnic, or progressive rock, depending on the disc-jockey. Airshifts were assigned by the program director, but the schedule was not strict i.e. the station would sign off and on depending on whether the DJ showed up. Record service consisted of a smattering of 45s sent from a few of the major record labels. In 1973 several of the progressive-rock oriented students became very involved and vowed to clean up the lax formatting.
