While at home I monitor all 3 systems (P25, city analog, county analog); but when mobile I've mostly only been monitoring analog and I've noticed the traffic level is not what it used to be. I know there is stuff on P25 only. Thanks for the heads up.

Looks like UC Davis did some RF coverage testing with their new site in the early hours of Tuesday. They took 2 voice channels from the existing UC Davis system. Sounds SRRCS wants to have everyone off the old system and the Davis sites online before January.

Did you monitor any of this testing?

Do they still have a P25 control channel on the air?

I received a submission with the UC Davis Fire talkgroups and added them to the SRRCS P25 system. In light of the fact that they're doing site coverage testing, should we keep them in the database? Or hold off?

Are you asking if you should remove the UCDFD talkgroups from the UC Davis SmartNet system, or hold off from adding them (or, at this point, removing them) from the SRRCS P25 system?

If the former, UCDFD is still using their UC Davis SmartNet talkgroups as of September 9th. If the latter, I say any talkgroups that are submitted should be added, if the person submitting has verified them (either through listening or obtaining from other sources).

The new TGIDs added to the P25 system I can confirm have had West Sac FD and Sacramento FD radio IDs joining these past few months (running Unitrunker 24/7).

Thanks. By policy we don't add unverified talkgroup information. We also don't indefinitely leave "planned" talkgroup info in a system that hasn't cut over yet. However in this case in light of the fact that UCD Fire has a P25 site that has already been intermittently tested I think now is the time to add the talkgroups.

They're secondary users, so they can only use the radio system when talking to a primary user. For example, they used the radio system when they did a raid with Sheriff a few weeks ago. Secondary users do not have their own talkgroups on the system.

This week, the following agencies are starting their transition to the P25 network:

Elk Grove Unified School District, Safety and Security Department (Transportation Department has already transitioned)
Folsom Police Department (Fire Department has already transitioned)
Sacramento Police Department (Fire Department and local government departments have already transitioned)

Any update on the status of the Davis site(s)?
As of 11/14, the site has yet to be activated. It has not popped up on Unitrunker as a peer to Site 12 (Countywide Simulcast). I drove to Davis last week just to see if possibly it's broadcasting a signal in an isolated mode, but found nothing.

A new voice channel for Site 12 was added at 11:30 this morning. 851.0500 has been taken from Site 1 and transferred to Site 12. I'll submit to the database.

I've been noticing quite a bit of traffic from a new talkgroup, 2843, which does not show up in the database at this moment. Seeing as though Rancho Murieta Community Services District has talkgroups 2837, 2839, and 2841, then there is a gap until 2851 for Washington Unified School District, it would make sense to be from Rancho Murieta, but the traffic I hear involves making an entry into a house. I guess it could be security making a welfare check or something, but I'm trying to figure it out by context. Does anyone know anything about Talkgroup 2843? I currently have all known talkgroups that I know but don't care about muted, so when new talkgroups pop up, I hear them.

That makes much more sense, based on the traffic I was hearing, than it being Rancho Murieta Community Services... it was sounding more like law enforcement-type traffic; like it was a SWAT team. I was probably hearing them making a visit on a parole violator.

I have a question, one thing I have noticed that Sac's analog I can receive better than the digital.
The digital I can not receive well enough to say so.
Thanks

What scanner are you using? If you're using anything but the new SDS models, you're likely suffering from Simulcast Distortion.

My advice, for anyone who hasn't already done it, buy the SDS100 if you want to scan SRRCS. It's superior to anything else I've tested.

I don't have any problems monitoring it with my BCD996P2 and the new Larsen triband NMO on my truck. Just the occasional dead spot here and there (Arden/Watt, Downtown areas, Sunrise/FOB), but its been crystal clear everywhere I do get signal.

Depends on where you are too. Both SRRCS digital and analog reception is pretty bad from Roseville. Cant pick up p25 traffic at all on my BCD325P2.
