Was this associated with a Talk Group of just an affiliation request?
I'm not saying this IS what's being seen here, but often times when radios are connecting through a "bridge" of some kind they can be prefixed with a specific ID number.
We are starting to notice something like this happening on the American Electric Power (AEP) TDMA control channeled system here in the Midwest. It is believed that when a radio is talking in via LTE the RID number is assigned a prefix by the system and when it is talking directly through a P25 site it uses it's normal RID. It's POSSIBLE 167 or 1670 could be a prefix for a bridge of some kind being used by radio 7173. Again, not saying this IS what's happening here but it could be something to keep a lookout for.
I think I saw it go to TG143 which has seen a lot of DC30__ Radio Techs lately.

Some updates this week on the CRIS website, specifically the "history" section:
- 2020 - Phase 2 consisted of 20 additional 700 MHz RF sites bringing the total to 26 repeater sites. This extended CRIS North Valley coverage from Sacramento to Redding, added coverage in the Bay Area from approximately Clear Lake to Santa Cruz, and added coverage in the Los Angeles, Ventura, and Orange Counties and the major roadways in those areas. In addition, three Phase 3 sites were installed ahead of schedule, adding coverage from approximately Auburn to Blue Canyon along the I-80 East corridor. Refer to the North Valley Region, Tri-County Region, Bay Area Region, and I-80 East Region predicted coverage maps.
- 2021 - Phase 3 is underway and includes planned deployment of an additional 10 700 MHz repeater sites, bringing the total to 36 repeater sites by year end. These sites will add Central Coast coverage from approximately King City to Santa Barbara, extend I-5 North coverage to Yreka, and improve Bay Area coverage.
- 2022 – Phase 4 plans to install VHF highband repeaters sites in Mono County and 700 MHz repeaters in the San Diego, Imperial, San Bernardino, Riverside, and Kern Counties.

Well that confirms site 36 is at Williams hill. I wonder if they still have Fremont peak on the list. Anyone in SLO area see anything pop up out there?

Do you happen to have any radio ID's associated with these?

I do. Good idea.
TG 2063: 70098, 70070, 403, 270,
TG 2061: 70093, 70092
TG 147: 269
Based on your observations, I'm thinking Site 50 may be Mt. Konocti, which would have line of sight to both Cloverdale and the Butte/Yuba/Sac areas where it's been heard. @franks_ham pointed out it could also be Cobb Mountain. Hopefully he can narrow it down for us
Some interesting convos on Loma this afternoon. DC 705 at Morgan Hill Cal Fire, DC 709 CHP Golden Gate Dispatch and DC 721 roving. Using TG 137. Seem to be working on getting CHP Dispatch into the system. RIDs 270 465 467

After listening back sounds like they were trying to patch the blue channel to the CRIS with no luck

I didn't realize there's a Seigler Mountain site in the official documents. I think that's Site 50.
Heard on Mt. Saint Helena as well. I missed some of the traffic initially as I was busy with another system but I have the recordings. They were busy! I Saw TG136 come up for DC709 as well.

I got an interesting hit this afternoon. TG 2063_ENC_ (TDMA) from RID 70073. This was on Mt. Saint Helena.
This morning on Pine Hill TG149 showed up with just a registration.
TG 861 (CHP VAL-GOLD) seems to be hitting on most sites as well.

I monitor the Blueridge system every day, occasionally I might hear a transmission from the techs and Sacramento, I monitor from 7:00 am to 6:00 pm. I guess this sute is not used?
It depends on where the techs are and what they have active. As long as the site is still broadcasting CC data, when a voice hit comes across you will hear something. Most of these "key ups" are just a radio registering/affiliating with the system and then deaffilliation.

New application filed on 12/10/2021 for a VHF site at Sweetwater Mountain in Mono County. Three (Sherwin, Conway, Crestview) of the other VHF sites were granted and one was returned (Silver Peak).
All the Mono County licenses and presumably those upcoming for Inyo County are all on VHF-High. This just in time for both counties to switch to UHF as subscribers on a Mobile Relay Associates system. Interoperability has been present in the eastern Sierra for a few decades thanks to the huge channel capacity of the radios in each agencies radios. The only agencies not on VHF-High were State Parks (although the rangers have VHF mobiles in their vehicles), CHP (they have interoperability with anyone due to their mobile setups) and Caltrans with their 800 MHz system. The latter have VHF-Low mobiles in their supervisor's rigs for CHP communications though. Now UHF trunking is entering this situation and hardly anyone, except for some businesses, use that band in the two counties. I think CRIS was being designed here based on VHF interoperability, but now, they may want to consider designing for UHF as well.
