14 June 2019 Charleston/Beaufort Road Trip Scanning Report

On Friday morning, I called an audible and took a short road trip to Charleston, SC to visit Patriot’s Point and the North Charleston Fire Museum, then spent the night in Beaufort, SC before going back home on Saturday morning. As usual, I had the mobile station radios going but it was hard to pay them a lot of attention due to the massive amount of traffic I ran into during the afternoon in Charleston and the evening in Beaufort. The Whistler TRX-2 and Uniden Home Patrol 2 were recording what they heard, however, so I was able to go back and listen to what I’d missed. It turned out that there was plenty to digest from Charleston in regards to the Department of Defense TRS used by Joint Base Charleston and Naval Support Activity Charleston.

One of the good things about traveling around or through South Carolina as a radio hobbyist is the ease of public safety monitoring. For the most part, you really only need to monitor one trunked system – the Palmetto 800 system – and occasionally a handful of conventional frequencies. In the Charleston area the system is, as one would expect, quite busy. The automated dispatch system is also something I have to adjust to every time I visit (a computerized voice does the initial dispatch for Fire/EMS calls, with human dispatchers on the incident channels).

Unsurprisingly, due to all of the military bases near Charleston and Beaufort – MCAS Beaufort, Joint Base Charleston, Shaw AFB, and JNGB McEntire – there was plenty of MilCom activity to be heard in the area. The recordings yielded one mystery frequency: 236.250. It’s used by Grumman in St. Augustine, FL, but in this case, it was in use by fighters doing air-to-air combat training. None of the recordings caught any callsigns and it didn’t seem to match up to any recordings from the offshore SUAs or area Military Operating Areas.

There are also sites for the Department of Defense TRS in Charleston and the US Marine Corps TRS in Beaufort. The Department of Defense TRS sites in Charleston provided a surprise; when I was last in Charleston in 2016, Joint Base Charleston and what was then Naval Weapons Station Charleston and now Naval Support Activity Charleston were using talkgroups in the 28### range. On this visit, none of those talkgroups were heard, instead, the activity was on 7##, 8##, and 9## talkgroups. After listening to the recordings, I think checking the System ID of the sites in Charleston is in order to determine whether they’re still on the DOD TRS or if they’re now a different one. This trip was also my first opportunity to listen to the USMC TRS sites in Beaufort with something that won’t skip over the encrypted talkgroups. Everything I head was encrypted with the exception of what seemed to be one radio on one of the talkgroups. Interestingly, the recordings didn’t catch any of the unencrypted MCRD Parris Island talkgroups I’ve heard on past visits to the area.

What’s a road trip without good food? As always when I visit Charleston, I had to eat at East Bay Deli, one of my favorite sandwich shops anywhere. One of my favorite hot sandwiches is a Cuban, and East Bay Deli serves a great one. After settling in at the hotel in Beaufort, I decided to go supper at Lady’s Island Dockside and I wasn’t disappointed. It’s busy, very busy indeed, and I had to wait 20-30 minutes or so for a table, but it was worth it. The food was excellent and even though they were busy the service was still friendly – they were quick without acting rushed. I chose the Seafood Pasta (shrimp, scallops, and crab in a parmesan sauce over linguini) and it was excellent; the scallops were quite possibly the most tender I’ve ever had. Their cornbread is also worth a mention – it’s plain no frills cornbread, incredibly moist and delicious.

Over the next couple of days, I’ll be adding some blog posts about my visits to Patriot’s Point, including the USS Yorktown (CV-10), USS Laffey (DD-724), and Vietnam Experience Exhibit and the North Charleston Fire Museum.
