You still missed a few (e.g. 771.88125 on the Lagoon site). Here is an even more complete list:

According to the RR Wiki list those should be NCDPS radios.

Is there a list of the site locations? I am going to Brunswick County soon. I have the talkgroups programmed, but what site is closest to that area? I didn't want to leave all the sites programmed as I assume that will significantly slow down scanning.... I have the same issue here at home (Indian Trail) I deleted all sites except Monroe, but I am not sure this is the correct thing to have done... I'm using a new SDS100.. Thanks for any input

There are four sites in Brunswick County - Bolivia, Supply, Southport, and Pea Landing.

When listening to VIPER communications in Duplin and Sampson Counties, I hear 911 dispatchers say the following several times a day, every day: "Repeat your traffic. Your radio went digital."

I assume this occurs when the signal received at the tower site is not of sufficient strength for it to be properly decoded and the result is garbled voice (both for the dispatcher and on my scanner).
I know that this can be caused by the use of portable radios instead of vehicle mounted radios and I know that there is a large gap in towers where Northwest Duplin, Northeast Sampson and Southern Wayne counties meet (zoom in on the RR tower site map). I also realize that the VIPER system is not yet complete.

I was just curious if this is heard in other areas of the state every day.

This is interesting in that it seems every time I drive through the Sampson/Wayne (Mount Olive) area (exit 355 off I-40), all of my radios - including my G5 - have lots of trouble finding a good signal/tower...

On a related note - living here in southern Brunswick County, there are many times I've heard units in Sunset Beach and other places along the coast that are unable to communicate with the dispatchers and resort to using cellphones. Reception at my house is "iffy" on a regular basis from the two closest towers (Supply, Bolivia). When we get heavy rain, I even watch my G5 lose signal of times ("Out Of Range") only to return a short time later when the sun returns. I don't recall ever seeing any system reception degrade that significantly during a rain storm (but I've never lived along the coast before either).

Properties of higher frequencies, even worse for microwave systems. Since the TV change to digital and the use higher frequencies I lose some stations based on weather, rain or fog.

Will be in the Southport area in a few weeks for R&R, and I have never have problems with drop outs, but again I am using XTS and XTL radios.

I am putting together a few systems for NCSHP and other agencies on VIPER and I am only adding sites in the 2 or 3 counties I travel daily but I still want to limit the number of freqs scanned as to not miss much.
RR lists them all of them per site and highlights the primary and secondary freqs. Should I only add those to each site, or add them all?
Thanks
J

You can probably get away with only programming the primary (RED) and alternate (BLUE) frequencies for each site.

However, for the most part, programming all of each site's frequencies won't negatively impact scanning as long a you have a good signal and reception. Once the radio finds the proper control channel frequency, it really doesn't care about the others (unless the signal quality drops).

Question VIPER Counties

I was wondering something. For all the Counties listed under the VIPER system page, would it be fair to say if the Counties don't have TAC 1-8 or multiple TAC channels that means they aren't using the system primarily yet? I've noticed the counties that do use VIPER have a good amount of talkgroups including a few TAC channels. And some of the Counties that I know don't use it yet only have a few basic talkgroups like Fire, EMS, Sheriff, EM, TAC, & Mutual Aid. That seems to be the basic channels offered until primary use. Would this assumption of mine be accurate? I was mainly wondering because I was trying to find out if Alexander County was using the system yet or still using their VHF/UHF channels, and I can't find any info searching the forums here. Thanks in advance!

David

You can't really make assumptions. Some counties have their own systems... some counties are very small and don't need alot of talkgroups. In some cases, it could just be that all of a counties talkgroups aren't listed (yet) or maybe they are encrypted so we don't know which is which... lots of possibilities...

For departments that are still on their conventional channels you sometimes can find the primary dispatch channel being simulcast on their VIPER talkgroup. Bertie and Craven counties are this way.

Wouldn't it be nice if there were one or two folks in each county who were the "expert," so to speak, and the "go-to" person for scanning knowledge?
