No they had 4 pairs as opposed to 3 so each user was using 4/3 channels instead of 1

So they had 4 pairs for control channels? That would be the only reason to need 4 pairs. You don't need a frequency pair for each Talkgroup. A TG is nothing more then a "virtual" channel inside the system.

That's what I'm saying, a 3 channel conventional system would be more spectral efficient than a trunked system with only 3 TGs using 4 repeater pairs.

Brunswick County patrol vehicles get new VIPER system installed

Brunswick County patrol vehicles get new VIPER system installed | Crime | South Brunswick News

BRUNSWICK COUNTY, NC (WECT) – The patrol vehicles of the Brunswick County sheriff’s office are getting an upgrade that they've been waiting on since January.

At the beginning of the year, Brunswick County was approved for a new public safety radio system.

Officials stated in a press release that installation of the new VIPER system has begun and will take several weeks for all of the vehicles to have the equipment.

The sheriff’s office has reportedly set a goal to have all the vehicles updated by Memorial Day weekend.

Fast forward to June, I can now follow Brunswick County Sheriff "Full Time" now on VIPER. I can only speak for the Viper Wilmington site. Unsure if they still use UHF or what. Would like to hear feedback on how others are now listening to Brunswick County traffic.

Thanks

I really don't understand the poor coverage anyway. Don't seem like we have that much trouble up here in the mountains. Doesn't UNC-TV have a 6 or 700 ft tower at Winnabow? That's almost as high (above average terrain) as our one site here. Granted there are a few spots where an HT won't get out but that's with just one site. With the one site in the county and those in neighboring counties I think VIPER covers almost everywhere.

Default poor coverage

I did some testing on VIPER with a portable (HT), a moto 2500. On Holden Beach, East of the bridge, most of the time i would get a no service tone, other time it would be garbled on even receiving a signal. I would estimate that the coverage from the bridge to Lockwood Inlet is only 40 percent.
I understand this is the problem all the way to Southport and if you look at the site locations, it make perfect sense. the sites Brunswick County relies on are Pea Landing, Supply, Carlina Beach and Delco. draw a propogation map around it them and see the holes.

Exclamation Brunswick fire departments finally hooking into VIPER radio network

Brunswick fire departments finally hooking into VIPER radio network

Source: Brunswick fire departments finally hooking into VIPER radio network | StarNewsOnline.com

Brunswick County was notified Wednesday that 400 radio identification codes were ready to be installed in fire department receivers throughout the county, ending a wait that has left some expensive new equipment idle.

Once installed, the identification codes will help the departments hook into the VIPER network, a wireless radio transmissions system advanced enough to connect emergency personnel statewide.

Anthony Marzano, emergency services director, said they will be installed and dished out within the next week in mostly portable handheld radios.

"(The 400) doesn't cover everything but allows us to cover all the fire department portables," said Marzano.

John Grimes, Leland Volunteer Fire and Rescue chief, said about 166 radios still need identification codes.

"They don't cover everything, but we ended up getting a doggone good portion of 'em," he said.

The news partially puts to rest months of mounting frustration from a shortage of identification codes for $2 million worth of equipment the county and fire departments bought through a grant.

Without the identification codes, Marzano has said it's like owning a cellphone without a phone number. The situation grew worse last year when the legislature cut funding for expansion of the program.

The system, monitored by the N.C. Highway Patrol, can handle only a certain number of radios on the network at one time.

The county's fire departments have been waiting for the codes for a year. The sheriff's office and paramedic crews received identification codes last summer.

In the interim, fire officials used the limited SmartLink radio system, which makes it hard to communicate with other county agencies.
The SmartLink system was also costing the county money through the lease of a radio tower. Marzano said the lease costs upward of $25,000.

"As frustrating as it was to wait, the state has seen the VIPER program explode," he said. "The state agencies did the best they could."

Local news reporting: Hundreds of VIPER radios arrive in Brunswick County

Source: http://www.wect.com/story/20876461/h...rrive-in-bruns

BRUNSWICK COUNTY, NC - (WECT) - Hundreds of VIPER radios arrived in Brunswick County on Wednesday.

The radios will be used by fire fighter, EMS officials and other emergency workers in the county.

The state of North Carolina recently pushed local emergency services to sign onto the new VIPER radio system. It allows officials in Brunswick County to communicate with other law enforcement officers across the state.

The project has been in the works for a while and it is supposed to save the county $30,000.

Officials hope to have all emergency workers on the system by mid-February.

Sounds like more frequencies needed to be added to the Brunswick sites of Viper to support the additional users.

Anyone see any indications of new frequencies?
