For years Cal football has been on 810 AM KGO. About a year ago KGO was rebranded as KSFO and switched call signs on January 1st. Cal football was on KSFO this season but last night I was coming home from the game against North Carolina when KSFO didn’t have the postgame show. I turned the dial to KNBR 680 AM and I found the postgame show there. Did Cal football switch to KNBR? Or was it just because it was a Friday night game?
