If you're getting 167 NAC on 173.550, then you're picking up something other than this system. The NAC on the Randolph control channel of 173.550 is 4F1.

I’m very odd. I’m going to look at the ct fed stuff after work

 

[ecps92]

Nothing found in most of New England at this time, with the exception of those in CT hearing the NY/NJ sites

With site numbers that high, there are over a hundred sites to still find folks. 117? 122? 124? Thats saying there are at least 124 sites. I will recheck the local stuff here, willing to bet this is going to be in every major US city.

I don’t think there is a requirement to start at number 1. So I’m not sure that is any indication of the number of sites.

You are correct. Maybe they did that just to mess with you guys.

 

[RadioDitch]

My brother is going to be checking around NYC today. We'll see what's found. Though with what @pro106import is saying about Site 117's control channel in his location, I don't think New Haven could be out of the question either.

GTR8000 what software program are you running for your SDR?

That screenshot was from Unitrunker 2.1, if that's what you were inquiring about.

 

[motorcoachdoug]

ok thanks. all i have here is phase 2 in the Wash dc metro area. my county is phase 2 and the MD 1st System is phase 2 plus a few others. From what I understand it will not do phase 2 unless I am mistaken.

I don't use Unitrunker for voice decoding, only for tracking and logging system activity. It will track the TDMA activity, but won't decode the voice. You need something like SDRTrunk or DSD+ for P25 TDMA.

With 95% confidence, my brother and I can both say that site 117 is in Bridgeport or Trumbull. Its definitely not coming from across the Sound, as there were no indications of a signal from the south at the waterfront park in Bridgeport. The best readings of -41 were on the Merritt Parkway near the top of the hill in Trumbull south of Exit 49.

With 100% certainty, the site is definitely not in New York City or on Long Island.

Because we don't have an exact tower site, I'm not going to submit. I'll leave GTR8000 and W2LIE to make a call as Database administrators who know our history of work for the database.

This is likely on the "Hi-Ho tower" on Booth Hill in Trumbull. That site has had a number of federal agencies in the past, so the likely hood is high this one is there too.

Sounds legit, we'll go with that for now.

If anybody local wanted to check that with a portable to confirm, it would save a trip and neither of us would be offended at all. 🙂

In about three weeks I will be passing through there and don't have any issue taking a quick side trip to check, if it can wait.

So...trying not to make assumptions. But, looking at the map visualization, it looks to me like we might possibly be able to expect at least two more sites at some point?

I realize these four may not all be cranked up to 11 yet. Just saying. Why would you build a system in the Tri-State area for a major federal agency, which provides no coverage in New York City itself? And trust me, it doesn't. It was checked in four of five boroughs today. Seems to me like buildout isn't over.

Just my $0.02.

 

[GTR8000]

The lack of any sites within the city limits is a bit odd. Keep an eye on those adjacent site lists. Might not hurt to also sniff around the 406-411 band, although unlikely it's certainly possible based on the band plan, and it's a pretty safe bet that they're using APX 8x00 multi-band radios.

I would like to get hold of you sometime and see how you have yours set up. I have both those software as well. I am beginning to take the deep dive into the world of SDR trunking.

 

[dave3825]

Site 122 (C I Courthouse) has had zero activity since last Wednesday. In fact, all activity on the site fits in one screen shot.

But at least now I receive both sites 122, and 117.
