Were there any peers/neighbors advertised on those sites?


There are now... Along with a new system ID of 3D4. Interesting that on site 46.46 it lists 4.4 as neighbor, but 4.4 doesn't list 46.46 as one.

My guess with the mention of 3D7 is that @firemantom26 copied that site during a tropo event, likely didn't have a good signal on it, likely didn't have a good decode, and that the 3D7 was probably a bad decode. I say that because there are no other Duke service areas nearby that would be so close as to be a peer of the OH-IN-KY portion of the system and not be an actual part of the OH-IN-KY portion of the system.

Well, maybe we should reconsider that for a minute with a 3D4 in the neighbor list.

Your situation is similar to Tom's. The "other" system ID is tied to a neighbor listing for a site that has no CC. If there is no CC, then it's probable that the odd SysID is just some temporary thing as well. At least that's my take.

Looks like New Hill and Zebulon for the other two on WRVH885 and WRUV446 respectively. Although one has to be careful because there are a TON of NC sites with pending updates to add freqs. And those wasn't show up in the RR fcc database listing. Still, with that said, good bet that those are New HIll and Zebulon.

The NC folks need to start rallying sleuthers from all over to start checking their areas.

I agree "D" sites might be dummy sites for install techs, just a wild guess there, but obviously they've been working on it today.

I hope we can find people using SDRs and DSD+ FL to help out here in NC, sounds like it is coming alive here.

I'm using a rubber duckie inside the house on a SDR running DSD+ FL

Since this thread is in the multistate forum (where it belongs), you might want to consider making a post in the NC forums with a subject like "Duke Energy P25 is coming alive in NC" . And then in the body, provide the link to _this_ multistate forum and encourage people to come here to check for details and post. That might rally a few.

Since I'm already assuming 3D4 is wrong, and since site "29.29" doesn't have a listed CC according to its pier, I'm going to go out on a limb anyway and guess that 29.29 (with channel number 8-1576) might end up being Durham (East Durham Intertie) on WQOY788. IF the 8-1576 is correct, that freq would be 860.8625. And although it may be too early to tell, it likes like they may going in alphabetized order (not by City, but by location on license).

BTW - the map I try and take care of is now up to date (as far as existing/new-pending licenses go). Balloons or Circles with ? in them are simply sites that have some pending FCC updates waiting to be approved.

Duke Energy Google Map

It is NOT complete with full site locations and all frequencies on all licenses listed. That is still a work in progress. But I'll start working on the ones closest to East NC since it's been proven that they are definitely building out there.

Given that sites in North Carolina are coming online, I'm guessing that Upstate South Carolina isn't far behind. I'd like to check for control channels locally for any new activity. I don't see any new or recent FCC licenses for Duke Energy in my area. The OpenSky system appears to still be operational here.

Is it typical for Duke to use existing OpenSky frequencies for the new P25 system? I assume both are operational for some amount of time during the transition. Or are other locations seeing new licenses issued for use on the new system?

They might use freqs from an existing license if the existing license(s) have some unused freqs.

Check the Google map (I don't have all the freqs listed for SC sites yet, unfortunately -- but the licenses and pending apps are there). You'll see there are quite a few sites in SC with pending (not approved yet) applications - Those have question marks in the icons. And there have probably been some updates over the past year. You don't need proof based upon licenses though. Just check all the Duke freqs in your area and see if any are P25 TDMA CCs (no scanner can handle P25 TDMA CCs). In order to actually decode the Duke sites you need DSDplus or OP25 or a BTT (Blue Tail Technologies) device.

Good call on pending licenses. I hadn't thought about that. I do have DSD+ FL to use for decoding.

The Google map link gives me an access error.

I don't know why it would give you an access error. I just logged in from a computer at another location for which I'm not logged into Gmail, and it's on a different connection (Comcast). I was able to click on the link and open the map.

With that said, in the past couple of years Google have become whiners about free services... Maybe my map reached an astounding 52.5 views and this was enough for Google to want to prevent access unless I pay. I don't know.
