2005-2008 VIPER Discussion (Archive)

[Robbyboy]

As PBoy said, we will not update TRS sites unless they are confirmed. The easiest way to do that is to program all of the frequencies and as long as you are in reasonable distance of the tower you will pick up the Control Channel. Once you have the System ID and Control channel, send it along, we will post it. Just because the licence is active, doesnt mean that the frequency is... Upon Approval, an agency has one year to go active... Look at the VIPER database site and see the updates on the bottom (PDF Files) and you will see how far along each site is. Just because sites are not at 100% does not mean you will not hear anything. Onslow County site is not @ 100% but I hear a good deal of traffic (mostly 1 way).

Your mileage may vary....

Cheers

Greetings everyone ! First off, I'd like to thank everyone here for maintaining an active and informative thread here. I follow several states and local areas and this by far seems to have the best flow (for lack of better words) Thanks !!!

Now, I am sure a few of you may be able to answer this for me. I noticed on the VIPER East map that there are two site locations in Brunswick Co. (looks like along Hwy 17), but I don't see site info or frequencies for a Brunswick site on the rr database. How come, why not for?

Also, I am planning on driving through NC to Brunswick (from Ohio) for the Christmas Holidays. 77, 74/52, 40, 221, 74, 501, 130/190. By programming in the control channels for all the sites listed, am I likely to hear much activity enroute? By what I am seeing here, I also need to program in all the low band freqs as well? I am primarily interested in NCHP.

Thanks again guys..good job !!

Site IDs

Hey guys...as the primary admin responsible for the VIPER system I thought I would weigh in...the numbering system for the sites listed in the database is still very much in the guessing phase...so if you come up with accurate info PLEASE submit it or send it my way and it will help us make the system more accurate...
Thanks!

It appears that a few folks have computer trunking software or scanners that can decode network cell (site) information.

Maybe we can get the RR VIPER database updated with proper site numbering.

Current entries in need of verification:

Chatham County-Chapel Hill
Cumberland County-Fayetteville
Duplin County-Kenansville
Granville County-Butner
Halifax County-Brinkleyville
Johnston County-Archers Lodge
Nash County-Rocky Mount
New Hanover County-Wilmington
Onslow County-Jacksonville
Orange County-Hillsborough
Robeson County-St.Pauls
Sampson County-Newton Grove
Wake County-Holly Springs
Wake County-Raleigh (Archdale Bldg.)
Wake County-Raleigh (C&L)
Wake County-Raleigh (Durant Rd.)
Wilson County-Bailey

I monitored these cells with Trunker from south of Myrtle Beach more than a year ago:

Cell 10: 868.975 CC and 867.975 AC Onslow County
Cell 11: 868.5875 CC and 867.325 AC New Hanover County
Cell 16: 868.3375 CC and 867.8375 AC Harnett County

These cell numbers and frequencies might have changed since I monitored them.

Discrimator Tap

If I can find someone to build a discrimator tap for one of my scanners (My BC8000XLT is my most likely candidate, but I have one or two older ones that I can mod as well) since I do not feel froggy enough to modify it myself, Id be glad to do a little road trip to sniff site numbers out. The only problem is that my car blew up after I got here, so I dont have much money to do such a thing... Any volunteers ?

To stay on VIPER discussion tho, when I drove to NYC, I only heard a control channel on the Farmville site and ALOT of traffic on 4176 (System Maintenance) from the Farmville site.

It appears that a few folks have computer trunking software or scanners that can decode network cell (site) information.

Maybe we can get the RR VIPER database updated with proper site numbering.

Bad Talkgroup ID

In the VIPER db there is an TG 1552 IDed as Troop A District 9. There is no Troop A D9 per Lt Everett Clendenin in Raleigh. Not sure where that came from but it isn't valid.

73 all and good hunting,

Hey Larry,
Actually it is a valid talkgroup on the VIPER system it just won't get any use until the NCSHP decides to add a District 9 in Troop A I appreciate you catching that as I originally planned to include "Future Use" with that Talkgroup ID...I have gone back and added the "Future Use" to that talkgroup in the database....the talkgroup templates were designed for "growing room" if you will...there will be talkgroups here and there that have no use now but down the road may become active...I have a master list of every talkgroup ID on the Viper system and some talkgroups that are listed may never be heard but are there if needed...hope this helps!
Happy Monitoring,

Another potential user jumping on board?

In talking with my dad (volunteer ff) on Thursday, he said Surry County will probably be switching to 800 Mhz sometime in the future.

Based on the VIPER participating local gov't partners list, Surry County is one of them.

Two VIPER sites in the works are also Surry County sites.

Couple them with the VIPER site at Elkin (also Surry County) and they would probably have a majority of the county covered.

Does the math make sense?

The current site licensing sure does suggest the reality of a Surry County subsystem!

 

[RohnsRadio]

Troop A 9 will be the members that were DMV officers. They are now High Way Patrol officers or, soon will be. This came form a family member that was a DMV enforment officer. All DMV enforcemnt car numbers will change as they all complete training .

[CCHLLM]

I attended the meeting for VIPER in Surry County, and yes, Surry will have an 800 mHz system in the future, and some of the sites (I believe the number is 3) will also be VIPER sites. The current thinking is that the VHF systems will not be done away with until the 800 systems are fully implemented countywide for all Surry agencies, and that will happen over a period of time. As with ALL system transistions, the timetable for full implementation is only a projection, and much will depend on the budgets, grants, equipment delivery and installation schedules, surrounding counties participation levels and timetables (regional influences), yadda yadda yadda.

As for the DMV becoming SHP, that program has been going on for some time. The budgets are very different, so the transition will involve a lot of paperwork and asset reassignment and disposition changes. A lot of the DMV equipment was/is paid for by federal funds as opposed to the SHP stuff being mostly state funded, and it all has to be separated on paper and accounted for as such, so the accounting and disposition sides of it are a damn nightmare. The DMV vehicles have a lot of newer stuff that the SHP cars don't have, like better radars, newer cameras, newer radios, and so on that were paid for out of federal highway safety funds. Glad I don't have to do the paperwork in Raleigh to account for all that reassignment of assets.

WX4 thanks for the confirmation.

I noticed a fourth site on pboy's map above in Flat Rock. I wonder if that is a definite for a county site?

 

[CCHLLM]

I haven't kept up with the actual site licensing, so it would only be a guess, but I'd say it's a good chance. If things follow the normal course, as the money comes through and the county plans become finalized, the site licenses will start appearing in the FCC database as Surry sites, state sites, and Surry/NC combined sites.

Viper Tg2103

Programmed the Concord Site into the 396 about two weeks ago, finally started hearing traffic this weekend. However, thus far all I'm hearing is TG 2103. Sounds like NCHP. I'm only hearing the dispatch side.
Interesting part is this TRS is coming in much stronger than the Cabarrus County TRS. I live in Union County NC.
Anyone hearing more out of the Concord site?

TG Weirdness

Programmed the Concord Site into the 396 about two weeks ago, finally started hearing traffic this weekend. However, thus far all I'm hearing is TG 2103. Sounds like NCHP. I'm only hearing the dispatch side.

Noticed the traffic lately, also.

TG 2103 is actually 2096, Troop C, District 3. The talkgroup has been multi-selected by the telecommunicator. They can merge multiple talkgroups together and work them at the same time. Not a patch where the different talkgroups can talk to each other, though. Everybody hears the dispatcher at the same time, but when they respond, it is still on separate groups. Mutli-select would allow one console position to work several districts at once.

To confuse things more, 800 MHz and 42 MHz are multi-tasked in similar fashion. The dispatches go out on both bands, but replies come back on the respective systems only. You don't hear 42 MHz on 800 MHz or vice versa. The comm center hears all, but the receive audio is not patched out for linked retransmission. Trooper has to be talking on a 800 MHz radio for us to hear it on VIPER. Lo band VHF is still the primary NCSHP operating mode even where the new trunked system exists.

Good signal

Very good signal using only the handhelds ducky!

Anyone hearing more out of the Concord site?

Nothing more than what you are hearing, bonus.

Just like the Concord system, Rowan's VIPER control channel in Granite Quarry (outside Salisbury) comes in stronger than the Public safety TRS comes does and I have heard no traffic on the system and have been monitoring it since the first of this year.

new viper control channel 868.2375 very weak signal in Raeford does anyone know were this viper site is located?

 

[Robbyboy]

New Talkgroups

Enroute to my house tonight from work, I noted 20152 with activity from Morehead City PD... I heard it over the Jacksonville Site but I do not know if there are any shared Control Channels. I already submitted it, but it appears some local users are jumping on the bandwagon down here on the coast!

Cheers

Could Be This One

new viper control channel 868.2375 very weak signal in Raeford does anyone know were this viper site is located?

Closest site with that frequency is Slocomb, just northeast of Fort Bragg:

WQCT913
State Roads 1606 and 1607
Cumberland County
35-12-28.0 N, 078-52-31.0 W

866.1750
866.4500
866.7375
867.1375
868.2375

 

[JerGoTV3]

This might have been covered in this thread before, but I can't remember;
I want to scan various Viper Sites; New Hanover, Sampson, and Duplin Counties. Would it be ok for me to put all their freq's in one bank on the Pro-95? Or would that mess it up.

Thanks in advance.

 

[RohnsRadio]

that is what i do. you are only going to hear the strongest one. when the system gets "built out" that may not be a good idea. but now with so few useing here in this part of the state, i dont seem to miss much.

Most will tell you that it may not track correctly with more than one ctl channel. But as i said with the sites being so far apart, and you are going have to be sort of close to the site to get the scanner to lock in, i dont think you will have much problem.

Maybe someone else will add their insight to this.
