While traveling through Duplin County this past weekend,I heard TG 1776. It was "a" base could not hear them well enough to tell who but, I did hear base and mobile. I also heard a TG 1714 it was weak and base only.

Hello Everyone
Based on some of these questions, I think a refresher on the VIPER Smartzone system is in order.
I can explain it, but I think that Marshall is way better suited to answer that question. I dont want to bumble it and annoy him
.
Cheers

The question is what talkgroups will troopers have in their radios and where will they have access to these talkgroups.
Will each troop have other troops talkgroups or share just mutual groups? What talkgroups will be available statewide or on a regional basis? Keeping in mind that troopers can be deployed anywhere when a crisis arises.
The SmartZone and OmniLink can make any of these configurations possible.
Is Troop C being heard in Troop B on a mutual talkgroup, a roaming talkgroup, or what?
Base only traffic on the talkgroup suggests rebroadcast of 42 MHz for the respective troops.

When you hear only the station traffic, it's the low band station multicast you're hearing. The car is replying on low band or high band and that traffic is not repeated.
If you hear another troop's traffic in your troop zone, it means that someone in your area has a radio on the "foreign" troop's talkgroup. As soon as the particular radio that's affiliated on the "foreign" talkgroup leaves that talkgroup, you'll no longer hear any of that troop's traffic in your troop.
There's also the possibilty that you're hearing overlap coverage from a site within the other ("foreign") troop. The Shepherd Mtn site in Randolph County can be solidly worked from the southwest side of Stokes County at King. This is why they're networked. The networking allows the system to "vote" sites, eliminating that "overcoverage" effect from tying up multiple sites unnecessarily.

Another Cleveland County VIPER site NCSHP has applied for:
Bens Knob
Shelby, Cleveland County
35-33-55.0 N, 081-39-38.0 W
Actually Benn Knob. At 2,894 feet, it is the highest point in the South Mountains State Park as well as the highest point in Cleveland County. Right at the Cleveland-Burke County line.

Some interesting listening on VIPER Baker Mtn (Catawba County) today.
TG 4112. Microwave technicians working at MDN sites. Talk about modems, terminals, T1, LAN, and different circuits being routed. If I am not mistaken the MDT network is phone line linked. So they are probably switching over the mobile data sites to the new digital microwave system.
Conversation went back and forth with a tech who I am going to say was in Raleigh. Training Academy tower site was mentioned as well as C&L. Sounded like he was at the " headend" of the microwave network.
The statewide 800MHz voice link sounded really great.

It's phone line only where there is no micro site co-located with the trunk site. You could have been hearing traffic about switching from the analog microwave to the digital microwave, and Baker is a micro site. That's been done some time ago in some locations and is in progress at others.
Clingman's Peak is the south peak of what most people consider Mt Mitchell. It's also shown on topo maps as "Mount Gibbes" and is where all the radio gear on "Mt Mitchell" is located. "Asheville" is probably the Reynolds Mtn (Mt Meadows) site just west of the Parkway on the northeast side of Asheville.
Lost some of the trunk system network functions Friday when the generator transfer switch on Chatham Mtn (Terrell's Mtn) was replaced and there was NO power for a short period. Made for some really interesting sounds and trunk system antics on some of the talkgroups until Captain Microwave and The Gurus got it straightened out.

Are we able to monitor this system in CLT, and if so, which set of freqs?

Ok...thanks to Lindsay I have now been granted statewide access and I have started updating/correcting the VIPER info. I have converted the system over to a statewide format and have most of the active talkgroups ported over to the new layout. You can see what I have done so far HERE...please bear with me as it will take me a few days to get everything totally updated and looking good in the database...as always please let me know of any updates/corrections via MSherard@gmail.com or here at RR.com!
Happy Monitoring!

:mrgreen: Thanks to everyone for the info in this thread.
NCSHP licensing activity has slacked off the last week or so. No news in that department.
Baker Mtn. VIPER site in Catawba County has been getting talkative at times thanks to the SHP microwave technicians.
They have been working somewhere within range of this site. Since their talkgroup is statewide, some conversations pertaining to the eastern end of the network are also being monitored. A tech was heard fixing problems at Brinkleyville.
Troop talkgroups have been popping up, also. 2420 related to Greensboro. Sounded like a roaming one. 24?? was Raleigh dispatch channel. Best I can figure is that the techs were "bringing up" these talkgroups. Respective SHP troop units could have been cruising out west, as well.
It is going to be fun trying to identify all these talkgroups unless someone gains access to the actual programing plan.

pboy-
Thanks for all of your hard work keeping up with the VIPER site info out your way....please let me know if you come up with specific info such as Control Channel/Site Frequencies for the new sites....now that the system is setup statewide in the database I want to keep the site list as accurate as possible...and some of the talkgroups have already been identified and listed in the database (especially the NCSHP)....but please pass along any updates/corrections as you come across them!
Happy Monitoring!

Another talkgroup heard on Baker Mtn. site here in Catawba County. 19904. Brief signal check. This talkgroup has been identified in the RR database as Wake County roaming.
NCSHP licensing seems to have ceased for the present time. Could be that they have all that they can build at one time. Or, maybe they spent all of the current funding already.

Both. June 30/July 1 is fiscal year end/begin, so money and labor will be affected by the change in budget. And if you're hearing eastern traffic on a western site, that means someone in the western area has a radio with that talkgroup selected. Otherwise, there wouldn't be any of that talkgroup traffic heard on that site. Probably a tech or a comm supervisor.
NCSHP is modifying licenses now.
Wallace, Duplin County and Cane Mtn., Alamance County VIPER sites are each having an additional frequency added. Are 5 channel sites.
Logged two more talkgroups on Baker Mtn.
Both were Raleigh SHP. 2096 is already in RR database as dispatch. 2103 was traffic with "X-Ray unit", too brief to figure out the nature of the TG.
Interesting to find that all these troop talkgroups are apparently available statewide and not limited just to troop district sites.

I validated that the site in Kenansville two days ago. I heard some traffic on I think 1776 talking to elizabethtown. I do not know the nature of it tho. I also noticed the additional request for the Wallace site. As more comes up, I will report. The Kenansville site was not that far away but I could not hear it until I was in central duplin county.

I am still trying to figure out whether I can monitor any of this activity in the Charlotte area.
