VIPER Statewide Radio System Discussion

[RaleighGuy]

From the VIPER database. This is somewhat confusing. Are they all not backup, or is Wake SO dispatched
on Viper? I wouldn't think they are.

All Wake County TGs in VIPER are for backup only, with some exceptions not in the database. There are various TGs that are used for undercover work with other agencies, but not on a regular basis, and not specifically assigned to Wake County.

Wake County Talkgroups

Except for the Wake County Sheriff Dispatch talkgroup all Wake County talkgroups are for backup purposes only.

It actually looks like Wake SO is strictly on the Cary/Wake P25 system. Cary/Wake P25 Trunking System, Cary, North Carolina - Scanner Frequencies

As said above, all Wake County is strictly on the Cary/Wake system's SITE 2 only. The Cary/Apex/Morrisville traffic is NOT part of the Wake County system and is on SITE 1. There is a VIPER TG for the patch between SHP and WSO, however I do not know if it is still in use since under the new system they can patch directly from VIPER to the Wake system TGs and do not need the specific TG patch.

Is the confusion due to the fact there are Wake County TGs listed in Viper? I once asked something about this and was quickly corrected that Wake was not on Viper, although I could see the difference, I just left it alone. I had a question about the Viper sites in Wake. For some reason the responder thought I was talking about the Wake county system. Maybe some clarification could help from monitors in the area.

Not the location of Wake TGs', themselves. It is the Wake location of the NCSHP that is the problem.

Wake location of NCSHP? Are you concerned with monitoring NCSHP on Viper, or monitoring Wake county on the Cary/Wake system?

If you are trying to program/monitor NCSHP in Wake, you may be able to get by with programming one site near you. It all depends on if most of the traffic exists on all the sites. Scanning all eight sites will slow things down a bit, so programming only the Control Channels and Alternates would be best if programming and scanning most or all eight sites. It depends on how the units get affiliated with sites in the system. Wake is a large county. Locals monitoring NCSHP around Wake may be able to advise on that one. Due to the proximity of Mecklenburg and Cabarrus counties, I hear a lot of H5 traffic on the Concord site, but I don't hear all of it. I am pretty sure I hear most or all of Cabarrus E5 on the Salisbury site. Most Troopers in Cabarrus get near the Salisbury site pretty often.

I was hoping to monitor it. By having the NCSHP-Wake group within the Cary/Wake25 system. So, Since I split the Cary/Wake25 into two systems. I would put it in the Wake system. So, I could utilize those CC/ACCs'. Just like I have done with others(Chatham, Durham, Harnett, Lee, Orange, and Randolph)

I only scan one site.

What are you referring to as NCSHP Wake group? I am having a hard time figuring out what you are trying to do. Talk Groups of a system need to be in the same scanner programmed system as the sites of the system.

Bruh, enter CBC0 as the TGID for C3 into your VIPER system, not wake, and you will hear C3 (SHP Wake)

 

[jthorpe]

I know that. The confusion is. Since Wake upgraded from Motorola to P25, the CC/ACC is now part of the Cary/Wake25 system. Or do I create a separate 'system' entirely. So as to keep using the CC/ACC on Viper, specifically for Wake County?

Cary and Wake are two different systems that use the same core. You should program them as two different systems entirely... VIPER is also another system that has absolutely nothing to do with Wake or Cary P25 systems, and you program completely separate and apart from the other two.

There used to be a permanent patch to the Wake system from VIPER for C3 traffic. That patch doesn't exist on the new Wake P25 system anymore and I think that might be where his confusion is coming from. He would need to hit a VIPER site as close to wake county as possible.

Maybe so. There are Rowan County named TGs in Viper. I have had them programmed and have never heard anything on them. I was just trying to see if there was anything.

For the OP. There may in fact be some departments with their own system also simulcast on Viper. But none that I have monitored.. That does not mean that a city or county does not in fact primarily operate on Viper, but just because there are TGs for them in Viper, does not mean they are in use.

Rowan doesn't use those Viper TG's very often. Our main use of Viper is LZ Central (soon LZ Piedmont), and Statewide Events channels for training with other agencies. On occasion, you'll hear the Rowan Mutual Aid TG active, but that's only when the techs are testing radios.

We have access to Viper to communicate with the neighboring counties (Davie, Davidson, Iredell) that utilize it when running mutual aid or during a law enforcement chase. Rowan owns and operates it's own P25 system so the use of Viper has always been minimal. Our radios also have UASI for the neighboring counties (Cabarrus, Stanly, Iredell) that utilize it.

I already split them in two. I know that VIPER technologically, has nothing to do withe the Wake or Cary systems.

That is what I was thinking.

1330 - VIPER Statewide Events TGs Foxtrot 1 (51975) and Foxtrot 4 sound like they are being used for swift water training today. Currently setting up vehicles to be used in the training.

Salisbury has been updated in the database to reflect the new fourth zone. Let's not forget that eight years ago (yes, it's been that long) when VIPER was an ASTRO 4.1 system it had 4 zones. Zone cores can only support a finite number of resources and as the number of ASR sites, simulcast sites, console sites, etc increase, the system must grow with it.

While it is a convenient naming scheme and timing, the new LZ talkgroups don't necessarily have any connection to the fourth RFSS. 99% of the state related interop talkgroups have statewide access and the regionalized naming is only to help with spreading channel assignments evenly across the state.

 

[CFP387]

...the new LZ talkgroups don't necessarily have any connection to the fourth RFSS.

And there you have it class, I stand corrected. I'll still admit that my theory sounded good, but I was still wrong.

Bear with me as I have a few questions:

Any idea when the new LZ talk groups for the Piedmont area will start to be used?
What counties are considered to be in this new Piedmont zone?
Why was the Salisbury site the first to be moved to Zone 4?
Which other sites are scheduled to be moved to Zone 4 and when?

Last I heard, the new LZ talkgroups would be used starting in February-March, but that was several months ago. Attached below are the regions being used across the state. The entire document is also attached below.

Another NCSHP question? T"he Chapel Hill CC/ACC for Orange County works for their P25 system. But, It isn't working for Orange county portion of the NCSHP. Any ideas'?

It works fine for me, I was out there earlier today. Maybe you should tell us what sites you are talking about, what sites you are listening too. Both Chapel Hill and Orange County are on VIPER, they do not have a separate system, and NCSHP can be heard on the same towers (sites).

I put in the same CC/ACC(Chapel Hill) for both.
