Good evening everyone I have a question:)

Napa CHP Office 21 "Grape" does not seem to me communicating with Golden Gate Dispatch but rather a base identified as Central! That office has had repeater issues the last 2 years so I suspect it's involved with that, anyone have any info on this?

This is a great question to ask in the California Forum, rather than General Scanning, since most of the other areas (outside CA) wouldn't have the info you seek and you'd get better responses in the CA Forum.

Just click on REPORT in the bottom left corner of your post and ask the mods to move it. Please do not start a new post, as double posting is discouraged.

I've noticed the Emerald is now simulcast with Solano rather than with Marin in the last week.
That's not super unusual. They try and tie the Emerald either into Turquoise or the Violet or Grape/Turquoise for consistency.

The Amber (91 Redwood City) and Violet (34 Marin) are simulcast on the Amber since at least Friday. They had to pull the simulcast when the 5150 on the Richmond-San Rafael Bridge restricted the Violet channel.

I can't receive the Violet from my location, so I don't know of they can hear 91 units up there. Seems unusual to have non-contiguous regions simulcast. The Amber and Pink (32 San Francisco) are usually simulcast.

Amber and Violet used to be simulcast all the time until too many calls came out for "San Antonio Road" which both areas have and units from each area would respond to their respective San Antonio Roads until it was clarified, causing lots of issues.

I am surprised they would re-simulcast those two areas again.

From Solano County "22 Turquoise" I can hear Golden Gate to a South Bay Office sounds like "24 Ruby Units" based on some of the freeways and roads. CHP has some strange stuff going on!

The cool thing is I can hear Santa Rosa units here in West Sacramento as 22 TRQ and 17 EME are simulcast :)

@CityNewsSupport Are you sure that's Napa? When I went through the other day they were talking to GG.

Hello Frank
Just a follow up as of last Thursday Napa is still communicating with Central! The other thing is their signal seems weak! I may on try to run into the PIO and ask if they are having issues.

I just want to confirm, are you listening to one of the 42/44 MHz frequencies, or are you listening to a 450/460 UHF frequency?

I know there's been times when the Golden Gate and Capitol Ops UHF repeaters both open up at the same time with units from Golden Gate, usually an air unit working with the ground units on speed enforcement, and the Capitol "Central" dispatcher tries to hail the unit back thinking it was meant for them.

Hey Mc
Ya I am listening on low band 42/44 I wonder if they are being dispatched from the office? Seems like a strange setup!

Considering none of the "Central Division" Frequencies or areas butt up against Napa, that is quite odd...

I run multiple receivers on VHF low band from eastern Sacramento county. I usually have one radio dedicated to CHP. I don't lock out nor avoid CHP on other radios, so I'll often hear several signals at once. I've noticed for months when I am hearing the same transmission on different channels -- Grape, Violet, Turquoise, Emerald, etc; all in Golden Gate division. I pick up all those channels natively, but certainly some come in clearer than others.

Ok I know RR frowns upon links but I could not upload just the file so I posted some Napa CHP audio to you tube. Two units calling "Central"

Sorry for reviving an old thread, but I guess I found the answer to this.

A video for dispatchers week was posted today, interviewing the CHP Capitol Communications Center (in Downtown Sacramento), which I know from listening to their 450/460 frequencies identified as “Central”, and as far as I thought only handled dispatching for the Capitol CHP units.


In the video, they mention they dispatch for the Capitol units, AND they handle the Napa/Sonoma area with the Grape radio and taking 911 calls in that area.

I don’t know why, but this blew my mind as to me why they’re handling Napa/Sonoma from Sacramento and not from Golden Gate CC (Vallejo) or maybe even Ukiah.

Anyone know the reason for this?

Note the Capitol Communications Center (Downtown Sacramento) is a completely separate operation from the Sacramento Communications Center (which dispatches for the Black, Gold and Green).

Very interesting. Just a note, the Grape covers Napa County and the Sonoma Valley area (around the City of Sonoma). Most of Sonoma County is covered by the Emerald, which is dispatched by Golden Gate Communications Center (GGCC).

Anyone know the reason for this?

I would guess that it's just to spread the workload around, and take some of the load off GGCC. If you think about it, Napa is probably the most geographically isolated area in Golden Gate Division, with no Interstate or US highways running through it. So if you were going to pick an area to break off from GGCC, it would make sense for it to be Napa.

Still kind of strange though.
