Broome County P25 Phase II TRS
- Thread starter GTR8000
- Start date
My error, and I can't remember where I saw mention of this. I see Broome Public Safety has a microwave license there but that's all.
I have been given permission to share some info about this new Broome P25 system from a current highly placed New York State employee........we'll call him "Mr. Cuomo" .
-----------------------------------------------------------------------------------------------------------------------------------------------------------------
Broome County has joined the Central NY Interoperable Communications System Consortium, of which Cortland and Madison County ARE members. Cortland currently has their own Motorola core however they plan to remove it and join the consortium core in Onondaga at some point in the future. The only reason they haven't done it yet is because they will have to program every one of their current radios with the new system ID, and that will be very costly and time consuming.
Broome chose to share the Onondaga core with the other counties as a cost-saving measure. It is much less expensive sharing the on-going maintenance costs on a shared system. Splitting that cost seven ways just makes sense for the tax payers.
Lewis County chose to go with an E.F. Johnson system rather than Motorola on their own, thus they are members but do not share the same system.
Tioga County has signed a contract with Motorola and plans to also join the CNY system with Broome. They are still in planning stages. They will likely be site number 9.

Broome County's system was developed by Motorola as two separate sites because of the terrain and the number of sites needed for 95% portable coverage. There simply was too many sites and that caused issues without overlap areas due to the simulcast. It has caused issues with subscriber programming to have two sites, however radios will be allowed to roam between the sites.
Sub site names:
EAST SITE - Hawkins, Nabinger, Sanford, Deposit, Laurel Lake, Windsor
WEST SITE - Ely Park, Ingraham, Kopernik, Andrews, Union, Maine, Lisle, Pease, Old State, Kirkwood
Control channels will likely end up being Ch. 1 for each site however they may be other channels during startup.

Leave it to Cortland to NOT do something right the first time and end up spending more taxpayers $'s to 'upgrade' the system that should of been put in place the first time around. Probably go for more grant money or something to do it but it is still stupid to do it twice.
You can hear the intercoms on Lewis.
Lewis's TG 4006 is Law Intercom, and TG 4007 is Fire Intercom. TG 4006 is the same traffic that is heard on TG 311 on the 2AE system. TG 4007 is the same traffic that is heard on TG 312 on the 2AE system.
Thanks for sharing! Work has been so busy I haven't had time to submit info on the East Site which is now transmitting a control signal on 453.5875. Currently Unitrunker is only showing one additional frequency which is 453.875. Most recently that was used by the Broome County Airport personnel and was very active during snowstorms with plow to plow comms. The frequency was silent during the last snowstorm so I wasn't surprised when I found the East Site online. I suspect the airport is using one of the Broome County UHF frequencies as simplex for their ops as I am too far away to hear them. 453.5875 had been part of the 2 frequency Town of Union DMR system but during that same storm all Union Highway comms were on slot 1 and slot 2 of 460.4375 (which you see is channel 3 of the East Site). Channel 4 of the East Site, 453.725, remains active as the Broome County Transit frequency. I would assume that Broome Transit and Town of Union will have to migrate elsewhere before the East Site can utilize all four frequencies listed. Staying tuned for further developments.
The Airport repeater has been temporarily programmed to 454.425 so that personnel can continue to operate while the East Site is brought online using 453.875. Once the Airport personnel move to the new system the current analog repeater will be decommissioned.
Broome Transit and Town of Union will be of the first agencies to migrate to the new P25 system so that their current repeaters can be decommissioned and then those frequencies will be available for the East Site. Until then, the East Site will use only the first two channels.
Thank you for the informative reply. I had surmised those two agencies might be among the first to migrate as I know other new systems have first brought over non-critical services like highway departments. I was in DeKalb County Georgia in the mid-80's when they built a Motorola Type 1 Analog Trunked system. The road department and refuse collection departments went on first and then one day the conventional police channels went dead so I knew they had shifted (I didn't have an 800mHz scanner and none could trunk back then). A few days later the old frequencies became active with a lot of officers cursing the new radios. There was an extensive pursuit, foot chase and search involving many units and helicopters during which the trunked system somehow failed. Fortunately the officers had kept their old handheld conventional radios in their cars. They stayed on the old conventional channels for couple of months during which I bought an early 800mHz scanner and listened to extensive discussions amongst Motorola engineers and techs flown in every week as they drove around the county doing tests and talking about the system. I learned new terminology like "master controller". Of course they ironed out the bugs and were back on the trunked system permanently after a few months. Well that was 35 years ago so I'm sure things are much smoother when new systems are rollled out.
Let's keep this in mind...

Everyone, I wanted to bring one of our rules/guidelines to light because it seems some members are forgetting this fact. That fact is that there is a high possibility that your employer may be reading your posts on this forum. Some may not care and some will. Often in the radio communications...
My friend "Andrew" has some more info to relay.
Incidentally, being a righteous "state worker", (which some people claim is an oxymoron) he seems to have taken offense at the moniker I have hung on him........
Can't imagine why
-------------------------------------------------------------------------------------------------------------------------------------
All the P25 sub sites are now on the air, both East and West. East channels 3 & 4 will remain inactive until sometime in August. West channel 1 will remain inactive until at least August, maybe longer.

You know.. You're really not as clever as you think you are. We already know who "Andrew" is thanks to you already calling the guy out publicly a few post earlier..

I'm guessing these are some kind of inside jokes that I'm not getting. There's no way "Andrew" would know or understand anything about our radio system. And who would care if he did .?
Actually all of the information shared by helpful members is easily determined by review of the FCC Licenses, press releases, Unitrunker and monitoring the new system. Just some innocent monitoring enthusiasts with different levels of knowledge, equipment and locations helping each other understand the new system and how to monitor it.
I wonder what his brother knows about this system...
Yea, he's not here anymore, so I took over the title..
