Changes to the Mobile Communications America DMR System at Georgia Ports Authority Savannah

Some time back, I noticed that the Mobile Communications of America 800 MHz DMR trunked repeater system (TRS) at Georgia Ports Authority in Savannah had changed configuration; no longer was anything being heard with it programmed into my gear as as Connect Plus system, but the SDS100 was seeing it as a Tier III system. I didn't have the time to pursue it any further at the time and added it to my radio "to-do" list. Over the weekend, I stayed up all night watching the 24 Hours of Le Mans sports car race and decided to check the MCA DMR system at Georgia Ports off the list; letting the SDS100's LCN finder run on it while I worked on the Charleston Road Trip Report and watched the race.

Military History, Colonial History, African American and Gullah Geechee History, Civil War History, and BBQ in the "Holy City" - Charleston, SC Road Trip Report; 9-13 June 2025

For several years now, I've wanted to visit the International African American Museum in Charleston, SC, so for this year's Summer vacation I took a week-long road trip to Charleston. I didn't really plan it, but it turned out that a good bit of the History I took in on this trip centered on the African American and Gullah Geechee experience in the Lowcountry. In addition to the International African American Museum, I visited Patriot's Point (taking day and night tours), Charles Towne Landing, the South Carolina Aquarium, the Old Slave Mart Museum, the Old Exchange and Provost Dungeon, McLeod Plantation, the North Charleston Fire Museum, Fort Johnson, and Fort Lamar. I also tried three of Charleston's BBQ restaurants; at one of them I had the best BBQ I've ever eaten. During the road trip, I was able to listen to the area's military and aviation communications, federal and USCG communications, public safety communications, and more. I did very little on amateur radio during this trip; I had just a couple of QSOs on the 146.7900- (PL 123.0) repeater on the USS Yorktown at Patriot's Point and checked into the "Scanner Junkies" net on TGIF DMR using DroidStar on Thursday night.

Coastal Georgia Military Monitoring Recap; May 2025

May was a busy month with not a lot of radio time, but there were some interesting things to listen to during the radio time I did have. The Blue Angels, Golden Knights, F-22 Demo Team, and civilian performers were in Brunswick for the Golden Isles Airshow and the USS Iwo Jima (LHD-7) ARG and 22nd MEU were in the area for training. The military performers only flew on Saturday; unfortunately, thunderstorms moved in on Sunday afternoon and forced the cancellation of the second half of the days' show. Several foreign air force/government Gulfstreams were at the Gulfstream Savannah Service Center and several aircraft from other countries transited through Coastal Georgia. The Goodyear Blimp even transited through Savannah airspace one afternoon.
