U.S. Marshals Service P25 TRS (BEE00-4F0)

Site 127 is continuously rolling between three control channels.

170.5625
170.9125
170.9625

Peers 1.001 (NYC), 1.103 (Beacon), 1.110 (Freehold), 1.118 (Randolph), 1.122 (Central Islip Courthouse), 1.129

Since the US Marshalls have these two talkgroups below on the NJICS system, I wonder if we will see a simulcast as they transition over to this new federal system.

DEC	HEX	Mode	Alpha Tag	Description	Tag
5155	1423	DE	USM Dist 1	District of New Jersey 1	Federal
5157	1425	DE	USM Dist 2	District of New Jersey 2	Federal

Unlikely. One of the primary reasons for the buildout of the 4F0 system is to provide wide area coverage in the region so that they no longer have to pay fees for use of the NJICS.

In the last week I started getting close call hits of 170.9125 and 170.5625 both with a NAC 4F7. In the Old Bethpage area. The system ID is 4F0. Perhaps there is a site in Plainview or Melville. I hope this helps.

Those are both Site 127 control channels. Can you program the system with those channels in one site and verify that it's 127? Maybe see if you can narrow down the location? Thanks.

I get those hits while I'm mobile. I'll see what I can do.

Okay no worries, don't go to any trouble. We're pretty sure it's in Plainview, there is a lot of fed stuff there already so it makes sense. Thanks again for the report!

Finally got a brief grab w some light tropo on Site 115. I have been seeing 115 as peer to both Freehold and Lambertville. Not enough signal for peers or channels to populate on 115 this time. Perhaps South Jersey?

 

[lynchy135]

I don't know if this helps much in locating 115, but I loaded it into my trunk-recorder config on a remote machine I have in Beach Haven, NJ and looks like it connected.

I can try to get a Unitrunker capture of it when I'm there next week.

Interesting. Yes, 115 peers and the alternate freq as well as signal strength would be helpful, when able. My guess, KACY. We shall see. Thanks! RR does not take estimates of location, at some point it will need to be pinned down by someone.

Not entirely correct. Yes, we obviously prefer the most accurate data that can be obtained, however when it comes to trunked sites the official policy is as follows:

Trunked system sites shall not be entered unless a site location is known at least to the county level. Sites located by means of the "neighbor site" logs of control channel monitoring programs shall be entered in the Wiki for the system unless a specific or reasonably close approximation of site location can be made.

Fuzzy memory again, a search of thread reveals and refresh above recall on exactly what is permitted again. Close but again, not extract, again. Moving on, new intel on #115 with light tropo again. More data today.

Site 115 Primary CC 170.600 Alt 170.8625, Peers populated in the photo below. Ps tried for elusive #130 CC 170.3375 as reported by others. No joy.

Been watching 117 122 and 127 all day on only a few joins on 127. Not a peep on the other two. Anyone seeing any activity at all on any of the other sites? Just curious.

Some activity on site 1.

Just a few affiliations: TGs 30603, 32601, 32663 with RIDs 6326xxx.

So unfortunately I can't get my VMware fusion to see my RTL dongle on my Mac. I had it working yesterday, so don't know what the issue is. Here is a screenshot from Gqrx in Beach Haven. I have the raw record file if that is of any use. I'll try to get VMware working again tomorrow.

 

[lynchy135]

Still no go with VMware for 115. I started installed OP25 on my linux machine and here's what I got.
./rx.py --args 'rtl' -N 'LNA:47' -S 2400000 -f 170.6000e6 -o 0 -l http:0.0.0.0:8080

I ran the same command on Ocean County's system and it seems to work fine.

For those playing at home, I'm in the Philadelphia area and found site 1-130 control channel on 170.3375 MHz, 170.6250 MHz alternate. It shows sites 1-102, 1-115 and 1.128 as neighbors.

Site 1-130 and 1-128 came in about the same level from my location near PHL airport.

Watched both site 1-130 and 1-128 on PRO96COM, no affiliations or activity seen, but it was a holiday weekend.

Thanks, A search of this thread yields many mentions of 130. Same for 115. The location(s) are what is needed so that they can get into the DB.

 

[jgorman21]

Anything found in upstate NY Albany area on this yet? I’ve been looking around but nothing so far.
