I was visiting in the area on 02/28/2017 and was advised within 30 to 60 days there will be a new digital trunked system that all Horry County law enforcement will be using. Those of you who live in the area need to start searching for it now.
I could be wrong but it looks like they've licensed the existing trunked system frequencies for P25. I've seen in several counties in Maryland (including Baltimore City) perform a gradual "cut-over" by pulling users and frequencies from the old system and transferring them to the new system (the whole transition occurred over a couple of hours).
What I would do is create a new P25 system in your radio and enter in all of the existing frequencies. Then, add a wildcard (GRE/Whistler) or put your radio in "ID Search" mode (Uniden). The talkgroups will almost certainly change. Hopefully, the dreaded "E" doesn't appear when the new system comes up...
You can monitor the existing system along with the newly programmed P25 system at the same time. You may actually see/hear some activity or testing.
I'll be down in Ocean Isle next week... will poke around and see if I can find anything...
For what it's worth, there's a P25 control channel running on 859.7125 for several weeks now. If anyone has a pro96com setup, you might check to see what's going on there.
PS: I have it setup on a Unication G5, but have yet to hear a transmission other than the control channel.
Well, I made it...
I'm sitting on the deck at the beach in Ocean Isle with my laptop, PSR-500, TRX-1 - and a beer (of course!)...
859.7125 is indeed active - Pro96Com is showing several alternate CCs that are all frequencies listed on the current Motorola system. I'm seeing 1 radio ID (1260xxx) sending data (GPS?) about once a minute and a couple of radios chatting on TGID 6485 -- uh-oh..... encrypted! No callsign yet....
Will submit the system to the database a bit later....
Oh, at least right now, all Phase 1
EDIT: seeing a little more activity including some additional radios and talkgroups (which I missed live) .. I think at least one of the additional talkgroups was not encrypted...
System data has been submitted -- now, hopefully someone will pick it up and get it posted... things tend to be a little slower down here in the south than I experience at home...
If you catch an the new system IDing, I'm pretty sure the call sign should be WQDD662

I think it's actually WQYQ235 / WQYQ236 but I never saw it being sent.
It's interesting to me that this is not (so far) part of the Palmetto P25 1D9 system.
Contrast that to Beaufort, Charleston, Sumter and Florence Counties in South Carolina, who have all moved off their own trunked radio systems to systems connected to the 1D9 Palmetto P25 system. I read on this forum not too long ago that York County may join (link up to) the Mecklenburg UASI system or Palmetto P25 system sometime in the future.
I believe that linking to Palmetto P25 doesn't necessarily mean giving up control of your system, but I'm not well experienced with that sort of thing.
