After not finding this Randolph county P25 system online yet, and finding a different/unknown P25 system online doing grid testing, and driving thru Randolph county and not finding either P25 system online, I went digging into the Randolph Co Commissioner's online meeting minutes.
Apparently the crew that J&K hired to install the antenna's on Randolph county's south tower found some bolts that were put in backwards, and some bent bracing pieces, which put all of the work and monetary payments on hold until the Commissioners were happy.
There is information about this radio system in every meeting minute document I read on Randolph county's website, starting from July. It looks like LE will have some encryption also, although the SHF already has 9 APX 4000s that are unencryptable. In one of the meeting minutes one of the commissioners said they might as well buy all new radios that can be encrypted.
Just now, after this 3-site system is built and erected, is the Sheriff talking to the Commissioners about which public safety and public service depts need radios, how many, and how they're going to pay for them.
In one of the meeting minutes it said J&K was going to be able to build and test this system while waiting on FCC approval. So, this unknown P25 system that I'm only seeing and hearing on Saturday mornings, doing grid testing, may be the new Randolph county P25 system awaiting a new FCC license (for some reason). If this is the case, I'm confused on why this system would be 99% completed, yet nobody has even ordered radios for it yet.
The freqs for the unknown P25 system in the area, doing coverage testing are: 770.10625, 770.50625 CC, 7771.33125 SCC.
