I would be very surprised if KNBR's mix was 80% FM. When KFOG was still around, KNBR had very high ratings as a standalone AM. Did everyone suddenly shift to FM once KFOG exited? I doubt it. The Bay Area terrain is not great for FM. 104.5 can get a lot of static and inconsistent reception in many areas of the Bay. Also, you don't need FM for sports talk or Baseball. As a Baseball fan, I've stuck with the AM side...no static, strong signal and sound quality is good enough.Supposedly 80% of the KNBR combo listening is to the FM. That is why they added the simulcast:to protect the format.

The move to the FM simulcast was done to preserve any 25-54 listeners and to try to build a new base in that age group. The AM-only listeners were aging and not being replaced by ones in the desirable sales demos.I would be very surprised if KNBR's mix was 80% FM.
