Good catch.
VHF overlay for that section of the state makes a lot of sense. From those 4 sites, they should have pretty good coverage along US 395.

Yep, not a surprise. They said a long time ago in public meetings that they were going to use VHF and/or UHF in some areas.
Another little tidbit from the application attachments.
"The proposed station is part of a Project 25 compliant trunked radio system managed by the California Governor's Office of Emergency Services, also known as Cal OES. The station supports a statewide communication system with emphasis on providing interoperable communications between California's public safety agencies while supporting normal day-to-day public safety operations."

TG 143 with a RID of 435 came up on Mt Saint Helena today...No traffic just an affiliation.

Antennas are in place at Rocky Butte, Plowshare, Solomon, and Mt Lowe on the Central Coast.. Don't know if transmitters are installed and functional yet.

Site 1-18 (Mt Diablo) is transmitting again. My monitoring post is in South Sacramento. I haven't gone into the field to see if it's still actually transmitting from Mt. Diablo or if it's moved to a different mountaintop.

I want to know what frequencies they think they're using on this. Mount Saint Helena would kill any RF off Seigler unless they use directionals.

Just an FYI, this isn't new information. These maps have been on the website for a good while now. It would be nice if they would update them though ;-)State updated CRIS page including coverage maps listing sites.

Yeah, that's what I figured but darn you'd think they would update!

I wonder why they would put a microwave on Sonoma Mountain? Mt. Saint Helena and Diablo hear each other fine, no need to sub-link them.

Redundancy.
Wouldn't that be another 700 site then and not a MW (Microwave) setup...?

I might be wrong, but I think you still need a back-haul link from a tower site to the master controller in a trunked system (which I'm assuming is in Sacramento).
Those mountaintops mentioned might be planned tower sites for CRIS and would need a back-haul (microwave in this case) link to the controller.
That would make logical sense, but
1) It's the state
2) Why have that much overlap? That much overlap would saturate the area and if other local smaller areas go to 700 like SRPD has, it might affect them if not paying attention. SRPD and SMRCS have an overlap SCC as it is.

I definitely understand the concern. I will say that the state has their own block of 700 MHz frequencies for their exclusive use, no local jurisdiction will have access to that block. That's what they're using for CRIS.
As far as the overlap in control channels, Northern California APCO coordinates primary, secondary, and tertiary use of 700/800 MHz frequencies. There's a list floating around somewhere with the users and their frequency assignments. Usually (in my observations) a large regional system gets primary use of the frequency, with secondary and tertiary users also having use but must insure they do not interfere with the primary user (i.e. reduced power, directional antennas, preferred/emergency use only control channels when needing to rotate, etc.)

I'm aware of that coordination. Someone screwed up there but back to CRIS...It'll be interesting to see what *exactly* goes on Sonoma Mt.
