SNACC P25

[SCPD]

I was listening to the SNACC P25 in the Arden site control channel 859.46250 earlier this week and then it went quiet when they switch to digital.

I have noticed the old system seems to be input digital and outputting regular on the North Las Vegas simulcast site. I cant seem to find the P25 control channel that comes in good in Henderson I want to switch my feeds to the digital side soon, or may just need to a better antenna. But i would think there should be a control in Henderson due to the fact they are digital now. I'm sure in time it will be all switched to digital in the coming weeks when they can get everyone switched over.

Anyone come across any new control channels or switched over control channels on the P25 mode.

I have been monitoring SNACC P25 Simulcast CC on 853.9000 in unitrunker. It is listed as site 33.

The sites listed as peers to the simulcast site are:
site 21 - 859.9375 Apex?
site 23 - 853.3375
site 24 - 853.0500
site 25 - 853.0500
site 30 - 859.9625
site 31 - 852.8000

Peers for the Apex site are:
site 23
site 27 - 852.8000
site 30
site 33 - simulcast

In the RRDB it shows Arden as being site 22. When I put the CC freqs for Simulcast and Apex into unitrunker, it doesn't currently show a site 22, however, when I looked at my history for the system, I had info for site 22 up until 2-15-2016.

Ok got it going now thank you

Figure it out easy

Best way to find more info for a P25 system is download and run Pro96com. Download Pro96Com You'll see other sites and freqs and lot's more.

 

[SCPD]

Thank you will download and check it out

Screenshot I just captured.

Interesting that it's showing as Phase 2 there in that screenshot 'cause we all know it's Phase 1 so far (and hopefully will remain as such but sooner or later will probably move to Phase 2).

I think that might be a faulty tick in the program Phase 1 or Phase 2? I've seen it report phase 2 false on other systems. So not gonna hold that to solid truth.

Don's screen-shot from 2/25 doesn't seem to show the Arden Peak/Black Mtn SNACC P25 site info. I too noticed a problem earlier this week when all of a sudden, I stopped hearing Henderson PD when in certain areas -- it was because they seemed to fully migrate to P25 & stopped simulcasting on analog, and the Arden Peak (aka Black Mtn) P25 data channel that the RRDB lists is incorrect -- none of them had a data signal on it while I was a mile from the site today.

While in the vicinity of Arden Peak earlier today & with no antenna on my handheld radio, I searched 850-860MHz & came across TRS data channels on 853.950 & 854.7125MHz. I haven't had a change to research either freq yet, but I am thinking one is for the analog SNACC system & the other is for the P25 SNACC system on Arden Peak.

By the way, the RTC seems to have moved to a Motorola Capacity-Plus (TRBO) DMR system. They were pretty boring to listen to anyway, and hearing some of the drivers on the radio plus reports of some of the 'antics' of the passengers didn't exactly instill any confidence towards riding the bus.

Seems the 854.4125 site is no longer in use at all, or it could just be offline for some maintenance and upgrades considering the changes taking place on SNACC both on the analog and digital side of things. The frequency is still showing in Unitrunker as part of the system (4A36) but I haven't seen anything on it today at all - there's nothing on the frequency, not even the CC transmission.

And yes, the 854.7125 is the secondary (now apparently the primary) analog CC for SNACC. I suppose we'll have to give it a few days to see what happens and if the 854.4125 comes back into action at some point.

Activity on 853.950 appears to be where the RTC traffic has moved - it's still traditional Motorola Type II from what I'm monitoring with Unitrunker so far. Some Clark County Fire activity, LAS Escorts at McCarran and a few others but not a lot else. That frequency shows as Site 10 on Unitrunker, also.

The control used to be 854.4125 it changed sometime mid week to 854.7125. I am sure a lot of changes are to come.

I noticed different controls channels vary from day to day on the P25 system.

I found the current SNACC P25 system control channel for the Arden Peak (Black Mountain/Henderson) site. Since yesterday, it's been 853.900MHz.

Have they fully switch over? Ànd if so what is the best site to monitor all talk groups? I will be coming out there in 3 weeks. Thank you.

No. Since you didn't state WHERE in the LV area you'd be, the only answer is to monitor all analog & P25 sites.

Don's screenshot *does* show the Arden Peak/Black Mtn site -- it's now Site 33.

Does anyone run the BCD436hp besides me? I have been scanning for over 30 years and have never had the frustration I have had since Henderson PD switched over to the p25 system. I've tried all the ways to scan and hit a wall with every effort. From wrong information on RR, exhausting all my mental resources trying to follow provided instructions on how to do things on, even the 'simple" to read instructions provided on the net. for the BCD436 to search.etc, etc,etc.
Any suggestions besides give up scanning for my preferences, shoot myself, start drugs? LOL
All suggestions to expedite finding these mysterious, now used control frequencies and correct site information would be appreciated. So far I only have a frequency that picks up the Henderson Fire Dept.
Thanks for any direction!

You could youtube it. Lot's of programming videos from K4DPS. You could for the time being create a site in your favorites list and enter all the control channels, call it cc only or something? If you're not worried about actual site names? Things are changing with the county radio system. All moving over to digital p25. Once the changes are complete we can figure out the whole system and update the rrdb. Did you say only HFD is heard? Try checking what service types you have active? For HPD you'll need law dispatch, law talk and law tac. MENU/select service types/ then toggle on/off what you want.

Im moving to Summerlin on the 19th and have a BCD436HP so I will be able to help map the SNACC P25 system and the future NSRS P25II system. Give me a couple weeks to get moved in and set up.

Good idea for now, thanks. I'll try that!

All the Henderson PD traffic is now P25 obviously and can be monitored off the 853.9000 site (002-033 in Unitrunker. The RR database info is obviously now tragically wrong on many respects but things are changing and shifting around so fast - like within the past two weeks - that nothing is "set in stone" just yet and could change even more.

I'm sitting here staring at 853.9000 at this moment and I see HPD along with NLVPD traffic every few seconds so that's where it's happening. As I don't own a scanner personally I would suspect if you could alter the primary control channel information for that CC frequency in Sentinel (never used it) that should get you some activity. Might have to go so far as to create a new system on the scanner, perhaps, just till all the data becomes solid in the near future and Sentinel's database accounts for all the actual real-world changes that are taking place, maybe?
