@norcalscan and @mcjones2013, could site 71 be Pine Hill?
That'll need to be a @mcjones2013 hunt, as Pine Hill is well outside my sphere of investigation. (speculation starts) I'm curious though 71 is still a peer to Tehama County's Round Mtn site 78. That just seems quite the distance, especially with Sutter Buttes site in between both logically and physically. I guess it could be redundancy if Sutter went offline; Round and Cohasset could hand off further south. @CopperWhopper67 the possibility of 71 being Vaca is purely my internal speculation/notes based on peer-mapping of the sites and knowing where RF coverage/gaps are in my neck of the woods. 71 could certainly be Pine Hill, downtown Sac, etc. It makes sense with all the other known peers other than 78. :unsure:

I picked up 171.7625 NAC 4D7 in Patterson yesterday (possibly Mt. Oso?). Since Site 71 was suspected to be Mt. Vaca, I thought it must be Site 72. However, today I ruled out Mt. Vaca for Site 71 (I was on a hill receiving CRIS and Solano SO/Fire on Mt. Vaca, and not a peep on 171.7625).

Therefore, I'm not sure whether I was receiving Site 71 or 72 in Patterson. I changed them both back to unknown for now.

Looking back through this thread, Site 72 was received in Visalia (with a different frequency), so I was most likely hearing Site 71 in Patterson.

I've updated the sites and neighbor lists as best I can from this thread, but I'm going to post a new thread in the statewide forums so hopefully folks outside the Bay Area can help us figure out some of these unknown sites.

Just a small update that I've noticed the last few days...This is all heard off the Mt Saint Helena site via DSD+FL

Mt Tam, Mt Diablo, Mt Vaca, Big Signal Peak (Mendo Co), and Site 84 all report ISOLATED/Site down status and then back up shortly thereafter. Site 84 shows "Info Outdated" as well.

Regards,

I've had DSDPlus locked on Mt Diablo (Site 69) for the past week. I've had a little traffic on some encrypted talkgroups. This popped up this morning. I'm assuming the registration in the red font is a radio from an outside system trying to roam onto this system, which is interesting, I haven't seen that before myself although I know the ability can exist. It appears to be a radio from the San Francisco P25 system, although it's being denied, at least on this specific site.
