KCSM ceased regular programming on its analog signal, over UHF channel 60, on May 15, 2004 due to a costly rent increase for full-power transmitter space. The station ran a billboard for the next several days advising viewers that they would only operate its digital signal from then on, though it continues to be available through cable. KCSM shut down its analog signal nine days later, on May 24. On May 3, 2005, KCSM received Special Temporary Authorization from the FCC to restore its analog signal at low power, operating on the campus of the College of San Mateo. It briefly simulcast the Jazz TV (60.3) feed for two hours every evening, with the rest of the broadcast day being a simulcast of KCSM (FM), but now offers only the simulcast (with relevant video "bulletin board" screens).
