This is all old and invalid information. For example, 42.440 is not even used at all anymore for some reason. It was the old pink but pink is another freq. now.

Here's what I've got so far on the CHP. Note that the mobile call signs are
usually preceded by the office number, thus fixing their general location.
There are some exceptions, including aircraft and inspection vehicles, which
may have a name plus a number ID, i.e., "Air 34" or "Golden Gate 24".

I'd also like to hear from anyone who can fill in the blanks.
