MCAS Beaufort TRS

MCAS Beaufort, SC now has a 9600 baud P25 digital trunked repeater system. Over the weekend, I first heard a control channel for the system during a slight band opening. Earlier today, I took a trip to Beaufort to do some further listening to the system and found the following:

System ID: 0032h
9600 Baud P25 Mil UHF System

Sites:
386.725 - 0032h-0101 - Control Channel
386.1375
386.9625
386.5125

380.4875 - 0032h-0102 - Control Channel
(No talkgroup activity noted)

385.625 - 0032h-0103 - Control Channel
385.350
386.2125

I didn't come to any full conclusions on site locations while I was up there (in part because I'm not completely familiar with Beaufort's geography. Site 0101 is definitely on or very near to MCAS Beaufort, that much I am sure of. 0103 seems to be further to the south; I had good signal strengths on it in the area of US 21/SC 170 all the way down to SC 170 at the Beaufort/Jasper County line although it drop out at times in the area of Beaufort Memorial and spots along Ribault Rd. 0102 has me somewhat perplexed. I think it may be on MCRD Parris Island as it came in VERY strong crossing over the Lady's Island Bridge (where you can look straight south down the Beaufort River and see MCRD PI). Passing by Parris Island Gateway on SC 802, however, there was almost no signal strength on it so that leads to a bit of confusion on my part.

So far, the only Talkgroup heard on the system has been PMO (MPs) on TG 38141. I'm guessing that the system has not been up very long and that not many users have migrated over to it yet. I would also like to thank a source in Beaufort who shall be anonymous for now (because I forgot to ask him if it was OK to mention his name).
