Ok Friends, I am brand new to CRIS -not to scanning though- and figured I'd fart around with it to see if I can hear anything. I live at the base of Mt. Diablo. I have programmed CRIS into my 996P2 via Freescan and into my SDS100 via Sentinel. I get a consistent "ID searching" message. Am I missing something or are trasmissions still periodic? Freescan screenshots attached.Screenshot_20221221_040923.pngScreenshot_20221221_040942.pngScreenshot_20221221_041002.pngScreenshot_20221221_041019.png

There's not much traffic on the system.

If there is a way to do a "TG Scan" of the tower, that is what I would suggest doing at this point, because as @officer_415 said there isn't much traffic on the system yet.

I haven't been following the thread but I have also noticed that sites are now advertising peers. Here's what I can hear:
  • 769.90625 MHz, Site 24: neighbors 25, 40, 51
  • 773.08125 MHz, Site 25: neighbors 24, 26, 27, 28, 51
  • 769.40625 MHz, Site 27: neighbors 25, 26, 28, 29, 30
  • 769.96875 MHz, Site 29: neighbors 27, 28, 30
  • 770.44375 MHz, Site 40: neighbors 24, 39, 51
  • 773.05625 MHz, Site 51: neighbors 24, 25, 40
These are the site frequencies I have purely from the neighbor lists:
  • Site 24: 773.08125 MHz (Rincon Peak)
  • Site 25: 773.08125 MHz (South Mountain)
  • Site 26: 769.20625 MHz (Tejon Peak)
  • Site 27: 769.40625 MHz (Oat Mountain)
  • Site 28: 770.20625 MHz (Hauser Peak)
  • Site 29: 769.40625 MHz (Mount Lukens)
  • Site 30: 770.44375 MHz (Santiago Peak)
  • Site 39: 773.05625 MHz (Mt. Solomon)
  • Site 40: 770.44375 MHz (Santa Ynez Peak)
  • Site 51: 773.05625 MHz (Red Mountain)
This produces a structure like this:

The problem is nobody is using it as their primary radio system (except Mono County). I suspect it's going to end up as just another underutilized interoperability system (like VCALL/VTAC, UCALL/UTAC, 7CALL/7TAC, 8CALL/8TAC, CALAW, CAFIRE, etc.)

I think the main reason they are under used is because many agencies that interop with each other already had plans in place and it works for them along with radios that can hold hundreds of channels. All the public safety agencies in my area have each other’s channels in their radios so all it takes is a couple button presses on their radios and they are talking with each other.

Then WHY, WHY would this system be funded and built? Listen, what both of you are saying just might be true, but would a builder of commerical Malls get investors to not only get funding and expect business to occupy that mall?

Because there is a need sometimes when you have to travel far outside your local area. My city FD has my county FD frequencies in their radios but not the next counties or their cities because they nearly never go there but they have because of a once in a career fire that required many multiple tower trucks or another time there was a chase that spanned multiple counties and while it was my counties suspect, they chase ended up deep in a town a whole county away that we weren’t familiar with.

We again need to understand that this system is still getting started.

The past few posts here are also the reasons why most of the regional P25 trunking systems should join the state core and become one large system. Take a radio from Los Angeles to an incident in Reading and everyone is able to talk to each other, and the LA units can talk back to LA from Reading with no need to connect anything together on the fly.

I do believe this will eventually be the direction this system goes over time.

Take it from someone who is experiencing a true "statewide" radio system right now, this IS the way to go.

Where's "Reading" CA? I've never been there and I've touched A LOT of land in this states. ;) :LOL:

As far as recording things go, Mt. Saint Helena has been very very silent besides an occasional registration.

I recorded CRIS Loma during the overnight hours these last two days. Have heard Felton Fire on TG 4501 and identifying the TG as "SelTac" or "SolTac". Maybe "FelTac" since this is Felton Fire. They were working storm related issues. Only heard traffic during these "mid shift" hours. Nothing else.

Mono County is NOT using CRIS as their primary radio system. I've had all the CRIS frequencies on the Sweetwater, Conway, Crestview, Sherwin Summit and Silver Peak Electronic Sites in my scanner since the 29th of December and hooked up to a logging system. All I've heard is a Morse Code ID on Conway, Sherwin Summit and Silver Peak. I've picked up a trunking data signal from Silver Peak twice in that time period, but it is not constant. I don't have Leviathan Peak programmed as I can't hear it from home. It only covers a small portion of the county anyway, with Sweetwater being the site that covers the north county best. If Mono County decides to use CRIS it would need the Antelope Mountain (near Benton), the Casa Diablo and Substation Hill (east of Mammoth) electronic sites to be CRIS equipped also. It also would likely need sites on June Mountain and Potato Peak (east side of Bridgeport Valley) to fill in specific locations as well.

I don't know where you received information about Mono County using CRIS as its primary system as it hasn't happened at this point in time. Your conclusion that CRIS will be an underutilized interop system is yet to be seen, but I tend to agree with you unless proven otherwise.
