A lot of radio fans have probably juxtaposed these 2 calls, but at the risk of being "picky", just wanted to point out that "LAist" is KPCC 89.3 (named after Pasadena City College) , and KPPC 106.7 was named after the Pasadena Presbyterian Church, where the underground music station was located in the basement.
When I went to school in Pasadena (1976-1978) we took a field trip to KPCC, on the college campus. (Some of our teachers also taught part-time at PCC...) We got a tour of the studio, etc. (I don;t recall if I saw the actual transmitter there). Fun.
KPPC, I was told, was very low powered and could not be heard well outside of Pasadena. My experience with that station came in the early 1990s, when I was working in Pasadena. KPPC would start its broadcast day at 5 pm, just as I was leaving work. It made KGIL-1260 impossible to hear, if I wanted to listen to Bruce Williams on the way home, I would have to wait until I got to at least Highland Park on the 110 freeway (aka Arroyo Seco Parkway),,,
