That's a good question as to what the state will do about those that are not 800 but are APCO 25. Personally, as I have stated before, I don't see ANY problem with an APCO 25 system that's not 800 mHz being seamlessly interconnected, technically speaking, but with state agendas and personalities, who the hell knows what will happen? Since the different freq ranges will dictate that some of the infrastructure will be different and will NOT benefit the state's agenda, the state seems to be discouraging the practice. I think the state is so dependent upon the grants for these individual counties and municipalities in order to carry out their own agenda that they're trying to sell it as an "our way or the highway" kind of thing, and it seems to have ruffled some feathers in more than one location.

The location in Ashe County is Phoenix Mtn, BTW, and my info says that the analog microwave will be phased out. Much of the UNC micro is co-located with the CCPS micro, so sharing will most likely become a common practice. The spread spectrum stuff is links belonging to various state agencies to make the shorter jump from the main sites to sites that are/were RF links without having to put in a full-blown micro site.

This tidbit that touches upon a previous discussion.


"Local Agency Communications Center access to the VIPER network"

"Connections to the VIPER network from local communications centers can be accomplished in several different ways. If the local communications center is already using Gold Elite Console technology, a direct connection to the SmartZone Embassy switch (AEB) could be made via microwave or fiber optic connection, or through the use of radio control stations connected to the Gold Elite Central Electronics Bank (CEB). If consoles other than Gold Elite Consoles are being used, connection through the use of radio control stations is the only available option. With the deployment of ACU-1000’s across the state as part of the VIPER Tactical solution, a potential for reuse of this equipment exists as counties migrate to the VIPER Strategic system. Utilizing the ACU-1000’s, dedicated connections could be made to support planned conversions from the current, locally operated radio system to the VIPER Strategic solution during transition."

Anybody else finding any VIPER technical stuff?

And that's what I was referring to when I mentioned that the connection has to be at a peer level. I just didn't wanna be the one to start the CEB/AEB/CIM/BIM ad nauseaum terminology so those who ain't wired to this stuff like some of us are won't begin snoring. :lol:

Thanks for the microwave map, PBoy. For years, I've been using an old photocopied map that was missing a couple of the system legs.

>> One of the 900 MHz category runs from Baker Mtn to Pores Knob to an unidentified site in Ashe County.

A multiplexed signal from Bakers Mountain to Pores Knob, carrying voice for the Pores Knob remote, the Ashe Co remote, and several voice channels for state Emergency Management, goes to Pores Knob on 953.550 MHz.

The tower at NCHP - Newton used to be used for this link, with the equipment in the shelter at the tower base.

A single-channel feed from Pores Knob to Ashe Co was on 957.500 MHz, with the feed back to Pores Knob on 953.900 MHz. The multiplexed feed from Pores Knob back to Bakers Mountain (or the NCHP comm center) was on 957.150 MHz.

You are most welcome.

900 MHz "microwave" is a bit misleading.

It is 900MHz linking similar to the 450-460MHz remote site linking NCSHP used to use a lot.

I guess a map a year old is better than none.

Been trying to figure out how much VIPER\NCSHP 800MHz now is an on the air reality west of I-77. The state intended to patch together something short term and surely by now a lot more things must be in place.

The Baker Mtn., Catawba County site really has me baffled. If it is live, I sure can't find any control channel. Unless it using Catawba County's 800 MHz assignments.

No matter what happens, though, with VIPER and its funding problems, SHP still is committed to 800MHz and has to build out some kind of a system.

VIPER info that other people have come across:

- Jeff Multer over on the Carolinascanner group came across FCC application for a NCSHP 800MHz site in Shelby, Cleveland County.

- RohnsRadio reports on this forum that Wayne County says no to VIPER and will build a VHF trunked system.

If you have any VIPER stories from your locality, please feel free to share them here. With 100 counties in the state there is a lot to keep track of.

Interesting for anybody in Iredell County...

These two sites are licensed the same 6 800MHz frequencies:

WQCR583-NORTH CAROLINA HIGHWAY PATROL
Location: INT SR 2345 & SR 2348, BARIUM SPRINGS
Effective Date: 05/09/2005
Construct Deadline Date: 05/09/2006

WPYJ823-IREDELL, COUNTY OF
Location: 201 E WATER ST, STATESVILLE
Effective Date: 08/25/2003
Construct Deadline Date: 08/25/2008

SHP has 6 channels instead of 5 at Barium Springs for some reason.

Does anyone visiting here know anything about 800MHz sites on Spivey Mountain near Asheville?

I found information that the City of Asheville TRS was renting space on a commercial tower there. Also, FCC license data shows a State of North Carolina 800MHz site on the same tower (exact same coordinates and antenna heights).

The VIPER build proposal calls for the reuse of a SHP owned tower there. That doesn't make any sense unless a separate state owned site is there. They are trying to use MDN locations but the mobile data site is listed at Peach Knob.

What exactly is going on at Spivey?

Thank you for passing that along basstuba!

From what I have read this year's funding is pretty critical to VIPER's overall success.

Tried to find out how far west any VIPER sites have gone live.

Seems like Baker Mtn. in Catawba County is it.

There is a pending SHP 800MHz license for Flat Top Mtn. near Black Mountain in Buncombe County. Nobody is reporting anything around Asheville.

Not looking like there is going to be any serious scanner listening west of I-77 for a while yet.

The project is scheduled out for the next 5 years (dependent on funding).

Will be interesting to see Charlotte\Mecklenburg VIPER. SHP has a license pending for 7 frequencies at the North Tower site of that TRS.

Everybody here needs to keep in mind that just because a site currently exists at a given location doesn't mean a new site won't be built or sites combined at that location and the old site(s) then passed on to other users, removed, etc. Spivey alone has more than one site and there are several others with that same circumstance, one of which comes to mind is Rich Mtn at Boone with at least three clusters of sites.

With respect to wx4chb's comments, it's fascinating trying to piece the VIPER build puzzle together.

For example. Mecklenburg County.

-There is a pending SHP license for the North site.

-Charlotte\Mecklenburg just relocated to that site.

-Charlotte\Mecklenburg is a VIPER partner.

Does that suggest that NCSHP is going to share its 7 frequencies with the existing system?

However, Charlotte\Mecklenburg already has a healthy inventory of
channels in use there.


Elsewhere on the RR NC Forum concerning VIPER:

-simpleman is asking for Halifax County VIPER info if anyone around
there can help him.

-jeffmulter has posted the latest SHP licensing data.

-basstuba sent me info documenting Scotland County's resolution protesting the way this year's Homeland Security money was disbursed by the state.

Does this "Viper" system go all the way down US 64 from Raleigh to the Manteo??? Do all these counties in the far eastern reaches of NC & the Outer Banks have it?

Hello murrayustud.

An early phase of the project runs the I-40 corridor into New Hanover County.

If you haven't already, take a look at a coverage map that is posted earlier in this discussion. It is a year old but probably still fairly accurate for the area you are talking about. Looks like VIPER is vapor.

I see that some FCC licenses have been applied for by the NCSHP in Pitt, Duplin, and Martin counties.

I can't find the information right now about what estimated completion phase that part of the state is in.

Duplin County has a 800 MHz (Viper) site up and running now. Has been up for 2 or 3 years now. Hear very little on it. I am told some of local cars use it but, if they do, I have never heard them. Seems the troopers would rather type (on their on MDT's) than talk.

RohnsRadio thanks for passing along word on Duplin County.

Over at Carolinascanner on Yahoo! there is a posting about Buncombe County proposing multi-county mutual aid communications. It would use an existing emergency management rain gauge monitoring system in WNC. There is radio networking capability attached to this system over state microwave.

Earlier this year the Asheville City Council authorized the application for a grant to purchase VIPER-compliant radios for both city and Buncombe County agencies. Asheville is a VIPER partner.

Nothing like keeping things simple. :roll:
