Anyone have any info on this system I'm picking up on 453.5250. DSDPlus shows it as being ConnectPlus, NID 141, Site 9 DCC 9 NL 1 7 8 23 26.

Major typo in first post, DMR ConnectPlus system is on 452.3250.

I haven't heard that Site (in SW PA) but I have seen sites 28 and 29. I think it might be a dealer network similar to, but not, TriConnex. Also, serving south-central PA.

During some tropo enhancement I copied the following:

454.19375? CON+ NID:141 Site:29 DCC:15 NL 19 25 26 27 28
454.345? CON+ NID:141 Site:27 DCC:13 NL 19 25 26 28 29

Of course I was using a drifting cheap nano dongle [the nanos get real hot and drift more than most other cheap dongles]. One could guess its probably 454.2000 and 454.345.

At any rate, real good bet its a big radio shop that has sites up over multiple states. Evidence between all of us thus far would seem to indicate two or three dozen sites.

I would doubt its a WV-based company. Probably PA or MD.

Perhaps Triangle Communications - http://www.trianglesc.com/triangle-communications-mototrbo-wide-area-digital-two-way-radio-system

Yes. Site 28 is 454.53125 and site 29 is on 454.19375. I looked for licenses, but none found. I thought maybe it was a split license so I checked 454.200 and 454.525, but found only paging companies with 16 kHz bandwidth.

I doubt it would be Triangle. They usually don't come this far west. I'm thinking maybe Centre Communications out of State College, PA.

Oh, and your last one was likely 454.34375 MHz. They are using 6.25 kHz channels for all the sites I've found so far:

27: 454.34375 - lower half of 454.350 - cc13
28: 454.53125 - upper half of 454.325 - cc14 NL: 19/25/26/27/29
29: 454.19375 - lower half of 454.200 - cc15 NL:19/25/26/27/28

I forgot to mention that I can hear 454.34375 as well, but it's pretty weak and I haven't gotten a good decode on it yet. 454.1975 is somewhat weak, and 454.53125 is the strongest here. They are likely using 454.35625, 454.51875, and 454.20625 as well somewhere. (the other halves of the known channels)

They seem to use a different color code on each site. One of these days I'll be on a hill and see what else I can find on that network.

Some 'suspects' to check: (if it is Centre)
462.0250 (+/- 6.25 kHz)
464.3000 (+/- 6.25 kHz)

Due to the high Site numbers, I'm thinking I'm only hearing the western or southwestern edge of the network.

UPDATE: Looking at that map you posted, I bet that's what it is. Centre still could be a part of it.

I agree with all of the above. Could be Centre, Triangle, or maybe even ICE. Probably Centre or Triangle. And I've seen a couple of wide area systems where various radio shops [whether they were related or not initially] combined efforts to produce a wide area TRBO network. There is on in Ohio / MI that I think also may stretch into CA.

At any rate, thanks for the info on the 6.25 khz. Not used to seeing that around here, especially on paging band, but that makes sense.

Key is to lookup the CP licenses in the FCC database for the states/cities and attempt to match up that way. I know Triangle has some CP licenses, but when I had looked it was difficult to tell if it was them because we don't even know where any of these sites actually are, and if we did we'd probably already know who the operator was. To add insult to injury, places that hold the market licenses for 450 paging often seem to "loan out" that spectrum to other radio shops but retain the license themselves. So ya never know.

I was mainly going by the 452.325 [in PA]. Quite a few radio shops have licenses, some trunked and others not. And for those that are trunked licenses, only Triangle lists TRBO emissions. Then again, its very possible for 452.325 to be in some other state, and it's possible that one of the other radio shops is building it out and just hasn't updated their licenses to reflect it.

I picked Triangle because they (a) have published info on a wide area trunked system, (b) have paging spectrum on 450 mhz, and (c) actually have documented YG licenses with TRBO emissions.

The Centre system looks like an older version of the Triangle system. I bet it's the same one. I wonder how long until they link in TriConnex.

Honestly, I'd be surprised if they do that... only because I don't think Staleys would want to in any way be associated with another radio company. Now, maybe they'd buy em out :). TriConnex, thus far, is only StaleyCom and Staley Technologies sites.

But I guess its not out of the question -- in an attempt to be the biggest and baddest of wide area CP systems, you have to join hands no matter who you are.

True, but Triangle and Centre appear to be working together...

DMRDecode log

Here's part of a DMRDecode log of the 452.3250 site. DMRDecode ran from 5 pm 11/16 until 8:18 am 11/17.

I'm confused. There is only 1 second of decode showing in that text file. Or did you cut off the first 15-ish hours?

There were no users during that timeframe so I just posted the end of the log. Forgot to mention that in my post.

OK. On 454.53125, I let it run for 24 hours a week or two ago and got:

5022 GROUP (Only used channel 2)
5025 GROUP (Only used channel 2)
5027 GROUP (Only used channel 2)

Monitoring: 454.34375
03:29:37 Current network: 141
03:29:37 Current site: 141-27
03:29:37 141-27 neighbor: Site 141-19
03:29:37 141-27 neighbor: Site 141-25
03:29:37 141-27 neighbor: Site 141-26
03:29:37 141-27 neighbor: Site 141-28
03:29:37 141-27 neighbor: Site 141-29

So at least I have the neighbors for this one now.

27: 454.34375 - lower half of 454.350 - cc13 NL:19/25/26/28/29

I was looking at site 141-9 (452.3250) for a while this morning. Saw something kind of strange, network 132, site 132-73 also showed up on the log, see attachment. Any ideas?
