OFFICIAL NYSEG P25 System Thread

Um, an APCO25 Phase One trunking system?

If your asking who is the manufacturer of the system, I don't know. I suspect its a mix of Motorola and other vendors based on the information discovered in this thread.

Thats the beauty of the APCO25 spec systems...you can mix/match vendors.

Would the program format be Motorola VHF digital to program my scanner? Thanks

 

[PJH]

If your scanner is capable of decoding the 9600bps control channel, then you will need to consult your manual for non-800MHz trunked systems.

This is an APCO25 trunked system. Open standard.

PJH thanks for all your help with my question regarding this system.

Does anyone know what type of trunking system is used by this system? I know it's APCO-25 Common Air Interface Exclusive system.

Do you mean the equipment manufacturer?

If you go to the FCC auctions you can see the blocks and the winners of each block in the Auctions. It was Auction 40 and 48.

Thanks for that! It was the missing piece in my data.

Hello,

I looked over the data on this site, FCC site, and Dave's site. I mapped out the known sites and was able to link the likely site numbers to a few site locations. I made up a kml file so it is easier to see where all the known sites are.

[DaveNF2G]

I was planning to do something like that, but I have not had the time. I will be interested in seeing how your project turned out. Meanwhile, I am creating midterm exams for my courses.....

 

[DaveNF2G]

Starting from scratch, and using the FCC database along with several NYSEG documents (filed with the FCC, so public records), I have constructed a map of NYSEG's VHF high band tx sites as licensed. The ones licensed under Part 90 (Public Land Mobile Radio Service - their business class licenses) and Part 22 (paging - the new frequencies) are in different colors. If both types of license apply to a single site, then that site has two markers.

I also used the Description blocks for each marker to list callsigns and frequencies.

Unfortunately, I added all of this data to my own myplaces.kml file in Google Earth, so I have to separate them out into a standalone KML file for sharing.

Of note -

I have found no evidence of transmitter sites at Mount Tom (as I interpreted the MOTO ID), Elk Mountain (as I interpreted EMT), or Austerlitz (AUS). HOOS does hold up as Hoosick.

The most likely candidates for Sites 121, 124, and 128 are Mechanicville/Clifton Park, Granville, and Cobleskill. I pick up site 124 sporadically and weakly, so I'm guessing Cobleskill for that one.

[EDIT] I have just added the Google Earth image of the network to my website as part of the NYSEG system web page. The link again is http://nf2g.com/scannist/0269.html .

Hello,

I thought MOTO meant Motorola rather than Mount Tom. As far as the other ids they could be NYSEG facility names rather than geographic names. The short identifiers do not help.

[DaveNF2G]

I think the identifiers would be very helpful if we knew what they meant.

I asked earlier in the thread for people to submit identifiers captured with Pro96Com. I have not received any others besides my own intercepts. Even if we don't know what the data mean, it is a good idea to keep on collecting it. A pattern could emerge.

 

[PJH]

The P25 spec allows site naming in the same way that Motorola SmartZone systems can. Typically its limited to 8 characters or less, and not always used. This normally works in conjuction with a RSSI read from the radio, and most of the time "rank and file" radios are not programmed to use this feature (no need, and KISS for the operators).

If no name is programmed into the site equipment, its typically identified as just a site number (Site 1, site 15, etc). However, unless a tech is out playing there is almost no need for that was well since the NOC has all the information needed in realtime (if a field problem became THAT serious).

 

[DaveNF2G]

I've added a revised map to the P25 system page at NF2G.com. I changed the labels on the Part 90 sites to their physical locations so they resemble the Part 22 site markers.

Also, I flipped the possible locations of sites 121 and 128 in the listing to make more sense based on my location.

 

[DaveNF2G]

I just added a network topography diagram to my NYSEG page. It is based on the listings of "neighbor" sites reported by the known active sites. Note that a network diagram does not resemble a physical map. I can rearrange the map so that known sites are in their relative physical positions to each other, but with the locations of only 3 sites positively identified, this would be a meaningless exercise right now.

I need folks who are using PRO96COM (or any software that decodes the "neighbors" data) to send me your lists of neighbor sites. You may use the Informant Form at NF2G.com, or email directly to feedback "AT" NF2G dot com.

 

[DaveNF2G]

The Google Earth map on my website now includes VHF low band licenses. At least one low band site apparently is being used for the high band trunked system.

I am looking for the following information:

-Frequencies used by specific sites.
-Talkgroups monitored on specific sites.
-Neighbor site data.
-Callsigns transmitted by specific sites.

Thanks in advance for any new info.

As always, the current NYSEG system page is at http://nf2g.com/scannist/0269.html

NYSEG has also acquired paging blocks on VHF low band in the 35 and 43 MHz range. None of these licenses have transmitter sites designated yet.

I plan to add site markers for licenses in the 160-162 MHz range shortly.

 

[PJH]

FWIW, NYSEG is using Motorola (IIRC) 1500 and 2500 series ASTRO25 radios.

If the whole system is Motorola, I am not sure, but I wouldn't be surprised.

Nyseg Action

Just want to let everyone know that there is a lot of action on 152.1425 today in Putnam County and northern Westchester County. We had a big storm go through last night and it blew down a lot of trees that brought down a lot of NYSEG lines. I can pickup communications on that frequency between the NYSEG trucks and what I think is their local Brewster, NY base. I cannot pickup any of the control channels published in the R/R database, but this frequency comes in loud and clear. I just programmed it into my BCD396T as a regular frequency and it comes in great using the rubber duck that the radio came with.

While I am talking about this trunked network, does anyone know how I would program this system into my scanner without frequency data, band plan, fleetmap, or other necessary trunking info ???

Search 151.7 to 153.8 and see if you can find the control channel. Progam the system as P25, enter the control channel and the scanner should run in ID search or wildcard mode. The best information on NYSEG is at www.nf2g.com.

Nyseg Trunk System

Search 151.7 to 153.8 and see if you can find the control channel. Progam the system as P25, enter the control channel and the scanner should run in ID search or wildcard mode. The best information on NYSEG is at www.nf2g.com.

OK, I searched the range you gave me and came up with a VERY strong control channel on 152.8000. I then made up a new system programmed as a P25 with only that one control channel and lo and behold, there they were. The SID on that control channel is 0269h-0130, and the talk group is 131. These guys are fixing all the downed electric lines in Putnam County and northern Westchester County. The frequency they are operating on is 152.1425, and both the control channel and the talk channel both come in with 5 bars on my BCD396T with the original rubber duck, so I would assume that the transmitter site is close by to me here in Putnam Valley, in Putnam County. Their office here in Putnam County is in Brewster. Thanks for the help and I hope that this post will also serve to enhance the listings here on R/R on that trunk system.
