California Radio Interoperable System (CRIS)

[OrangePelican]

Radio techs where testing encryption on TG 748 "Valley Gold" via CHP dispatch consoles today. It's now full time encrypted

The North Sacramento Area is starting their next test for switching to CRIS on the 19th. Probably getting ready for that.

I remember telling folks that CHP was going trunked many years ago, and being laughed at. I mentioned they were going full E too, again laughter. Now that it's actually happening, I wish I was hearing laughter instead of groaning and tears.

Very slowly. North Sac is the "test" area for now. If the dispatch infrastructure side goes well this time the rest of the Sacramento area offices will slowly be switched over. It will be years before the whole agency has switched.

The testing is the 15th did it get moved up ?

There are several dates floating around for North Sac going live. The earliest I’ve heard is 3/19/24. They have also talked about the week after. It sounds like there has been sporadic radio tech testing on the CHP talkgroups recently too.

They have also rescheduled this several times in the past and already tried using the system before without the desired results so it might be back to low band only again.

Hmm, seems a message in this thread has been deleted for some reason.

Anyway, Site 66 - Cal OES is now broadcasting a NAC of 9D6, instead of 9D7 that it was doing for a while.

Haha, thanks. DB updated.

Does anyone know if the Santiago Peak Site (Site 30) is a simulcast cell for the inland empire area? When I was in Rancho Cucamonga (30 miles away from the site) the RSSI level was in the -60dBm to about -70dBm and in the Chino (23 miles away) area about the same. Which for Santiago that seems way to good to be true if it is coming from one site with that level. I did double check the System ID, Site NAC and everything is matching. Additionally I noticed when in Orange County it has about -90 dBm when about 13 miles away from the site. Not sure if anyone has any information if they are going to be doing simulcast cells or standalone ASR sites.

I’m not aware of any simulcast cells on the system, I believe they’re all standalone sites. Some are pretty high power.

I'm in Anaheim near Disneyland and I can barely hear the Santiago site. It seems as though they have some directionality set up on it. Lukens is solid - that must be the intended use site for much of the L.A. basin. I have no way to confirm this other than my ability to pick up the signals.

Would the CRIS Tri County coverage map answer the question? https://www.caloes.ca.gov/wp-content/uploads/PSC/Documents/CRIS5-YearPhasedDeploymentMap4.pdf

 

[officer_415]

There is no simulcast, each site has its own frequencies.

Right, and based on the map Santiago is providing direct coverage to the north and northeast areas

Here's a video posted by CHP North Sacramento, who is currently in testing for using CRIS. While it's about an officer retiring, you can tell he's likely talking on the trunked system based on the talk permit tone and the dispatcher sounding digital (sort of... also could be she's on analog and it's being piped into the digital side).

Either that or the 700 MHz "base" frequency. I know they use that at the North Sac office, I've heard units go 10-10 on it multiple times while I've been at Madison staging.

I wonder if CHP has a last call talkgroup?

According to proposed time line, the Bay area should be 100% transfered to CRIS.

Could be a temporary patch between CRIS and lo band?

Once Nexts are issued to every officer Statewide , I'd expect 42Mhz to be silent in Bay area, now or very soon.

As each area switches, those will make 42Mhz silent as the switch expands?

@mcjones2013 is correct, the talk permit tone means trunking...which means CRIS

CRIS isn't even fully built out in the Bay Area. North Sac is the only area currently operating on CRIS.

Probably just a test with a Dog and Pony Show for testing and to video it and post it on the internet. Either way it really doesn't matter as it sounds like its working with no issues so far. I am pretty sure CAL OES has its ducks lined up and lots of testing statewide so far.

Not to discount either post but the talk permit tone doesn't necessarily mean it's trunking. Several radio models can be setup with a talk permit tone for conventional as well, especially digital conventional.

I was listening to Chp Gold on lowband when that radio transmission occurred for the officer that is retiring. I checked the Cris system with unitrunker and saw that he was actually talking on the Chp Gold Talkgroup. But dispatch was talking on lowband and it was being piped over to the Cris system.

was it encrypted on cris?

CHP will go encrypted once they are fully converted over.
