NSB Kings Bay Sites of the Southeast DOD TRS

Location: Kingsland, GA

This afternoon and evening have found me spending time in Kingsland, GA. In my down time, I've been monitoring the NSB Kings Bay site of the Southeast DOD TRS and a site that I believed is a second NSB Kings Bay site.

The site I thought to be the second Kings Bay site, using the control channel 386.1875 is definitely at or near NSB Kings Bay. The signals from the site are extremely strong on and around NSB Kings Bay and the talkgroup activity practically mirrors the already known NSB Kings Bay site. It is pretty safe identifying the site as NSB Kings Bay.

This being a Friday afternoon/evening, there has not been a great deal of talkgroup activity. Here is an overview of the talkgroup activity I've heard (it seems that the two have been simulcasting the same activity):

28053 - encrypted
28058 - encrypted/clear
28081 - encrypted
28087 - encrypted/clear
28563 - encrypted
28050 - Waterfront Security, encrypted
28562 - Police, encrypted/clear
28557 - Fire, encrypted/clear

Throughout the evening and afternoon I have heard nothing on the NSB Kings Bay 406 MHz TRS. I have heard some traffic on it during the daytime on weekdays before but it has almost always sounded civilian in nature.

Tomorrow I hope to have some more time to monitor the Kings Bay sites and some time to monitor the NS Mayport site. I doubt I'll be close enough to hear the NAS Jax site, but I'll definitely take some notes if I'm lucky enough.

US DOD Southeastern Region TRS

Yesterday (14 July 2008) I was traveled down I-95 to the Jacksonville area for a short trip into downtown Jacksonivlle. I used the opportunity to do some very brief monitoring of the US Department of Defense Southeastern Region TRS. Due to the nature of the trip, I wasn't able to listen closely and take notes, but I did put the BC-396 into search and store mode. The 396 picked up on the 386.050 Control Channel for NSB Kings Bay and the 385.5625 Control Channel for NAS Jacksonville.

This afternoon I was able to fully review the contents of the BC-396's talkgroup search and store bank:

19457
28050
28051
28053
28056
28057
28058
28061
28064
28081
62036

The 28### series talkgroups all seemed to be from NAS Kings Bay. From what little time I was able to listen, it seemed there was a lot of encrypted traffic. Some talkgroups seemed to be a mix of encrypted and unencrypted stations, i.e. the base station would be in the clear and the mobile would be encrypted. Likewise, during that short listening time, I did not hear any voice traffic (encrypted or clear) on the NAS Jacksonville Control Channel.

As far as 19457 and 62036 go, I did not note which Control Channel they were found on.
