JNCR radio system - Fort Hamilton?

[troymail]

Been noticing quite a bit of encrypted activity on TG 100 of this system

Joint National Capital Region Trunking System, Various, Multi-State - Scanner Frequencies

recently. May have been there all along I just never noticed. It typically appears on my radio as FtHamRescSrv but the RRDB database lists both FtHamRescSrv and Ft Belvior (VA) Fire as the user.

Listening to recordings and looking at the data, the clear voice being heard on the Ft Meade site in Maryland is definitely Belvoir Fire. However, preliminary information is showing those units using 6 digit radio IDs. The encrypted activity seems to be 7 digit radio IDs.

Can anyone confirm, etc. that TG 100 is being used by Ft Hamilton? Seems odd that two users on the same network connected system have the same TG.

My guess is - as I've seen in other users on the system - Ft Hamilton used TG 100 long ago but is now in a different range (11xx?) and the TG 100 entry is no longer valid for Ft Hamilton.

Still - curious in that I seem to be seeing encrypted traffic on that talkgroup (along with unencrypted Fire users).

Not knowing much as to why you can hear TG 100 on Fort Hamilton, the Fort Hamilton site is tied to the Harris NCR master site. If a radio tries to affiliate to Fort Belvoir Fire (TG100) at Fort Hamilton site, the master site will pass the audio traffic through Fort Hamilton site.

Ever since the Harris NCR master site went through the 10.X upgrade, I have seen some new talk groups at the Fort Hamilton site and the audio quality has improved a bit. That being said, Fort Hamilton MP is still 99% of the traffic here.

Getting alot of 7 digit radio ID (1103000, 1100219, 1101140, etc.) encrypted activity on TG 100 on the US Naval Academy site today.... still curious about this "dual labeled" Fort Belvoir FD (6 digit IDs) and Fort Hamilton RescSrv stuff...

Is this really Fort Hamilton?

Is Fort Belvoir FD going encrypted?

Why would we hear Fort Hamilton on the Fort Meade or USNA sites (and on a TGID that is also carrying clear Belvoir fire department users)?

Curious.

To ask the obvious question...

What does any of this have to do with New York?

Isn't Fort Hamilton in New York?

BTW - Noticing today more (related?) encrypted activity on TGID 114 with similar radio IDs (110xxxx)....

OK. I was confused because the thread participants were outside the state, discussing a system being monitored from outside the state. Sorry about that.

 

[DaveNF2G]

Even though this is relevant to NY, it seems to me that the JNCR would be more on-topic in the Multi-State Systems Forum.

Which people hardly ever look at. I'm not trying to get your goat, but I think it's needlessly nitpicky to say 'hey get your thread off my forum' simply because JNCR is a multistate system - Troy's looking for local New York knowledge on information about JNCR ops at a New York facility. We have a bundle of threads in the MD forum about JNCR too for the same reason.

Again, I'm not looking for confrontation... just questioning the persistent unwelcoming atmosphere of the NY forum.

 

[troymail]

Yeah - I didn't even think to use (or know about) multi-state forums. As was said - I'm hoping someone in NY can tell me if they are seeing the same TG 1xx activity on the Fort Hamilton site and if not, then (as I suspect) this isn't Fort Hamilton activity. With two exceptions, everything in the database in the 1xx range seems to be Belvoir...

I agree on initial look one might say (including me) Fort Hamilton is part of JNCR? Doesn't seem right but apparently it is....

 

[troymail]

BTW - I am now seeing similar activity on 100, 101, and 114 -- all 110xxxx radio IDs and encrypted.... not sure if these TGIDs were reassigned, Belvoir Fire just went encrypted, or the TGIDs are being shared by users other than fire department.... and if still Fire, seems like a bad sign to see fire department users encrypted....

I just watched my log for Fort Hamilton and I have not seen 1xx encrypted activity, only Fort Hamilton MP in the clear

Thanks - what TGID?

 

[CqDx]

Fort Hamilton MP is 1100. Radio IDs are 11003XX and 11008XX

There is also a patch from 8426 to 593 and 8426 to 501. You probably will see the same in your local favorite JNCR site.

Interesting - the RIDs I'm seeing on 1xx TGIDs (100, 101, 114) on the Ft Meade or USNA sites are 1103xxx and others - all ENC.

 

[CqDx]

I think it is safe to say that TG100 at Fort Hamilton was incorrectly identified as Rescue Services. I don't remember Fort Hamilton having its own fire department, certainly not its own talkgroup.

The radio ID pattern at Fort Hamilton has always been 1100xxx, whereas your encrypted radio ID pattern is 1103xxx.

 

[riveter]

Having suddenly paid closer attention to this, 100 is most likely erroneous there. The 1xx series is almost exclusively assigned to Fort Belvoir, and I hear them quite frequently on the NCR G and U RFSSs (including Fort Meade and USNA).

 

[DaveNF2G]

I did not mean to seem unwelcoming. My suggestion of a more suitable forum was meant to be helpful.

Not much to add here, but my Home Patrol 2 just picked up Fort Hamilton from Bayonne under the JNCR System as Military Police Law Dispatch TG 1100. Time was 10:05 AM EST 1505 UTC. Guy was telling Dispatch he had to change his radio. Haven't heard any other tg's.
