Ok, it's Saturday and I've dug out my old DFG radio communications map. This isn't something I can scan. It's a poster, probably 2'x4'. It has a map of CA with the counties drawn in, and the sites in each. It lists Base/Control stations, Control stations and Mobile Relay stations separately, with freqs and PLs for each.
To convert this into an Excel spreadsheet or text file would take hours, and it's dated 1991 so it's probably a bit old (although knowing the State, I doubt much has changed). If people have specific questions for specific counties, I'd be happy to answer them here.
