Cortland must have their own core...it's listed as separate system with a different system ID. Cortland County Public Safety Trunking System, Cortland County, New York - Scanner Frequencies

No, it has nothing to do with the talkgroups. You didn't state what scanner you're importing to, so no definitive answer can be given...but my guess is that you're relying on either Uniden or Whistler's database, which only get updated once per week. The Broome cell was only added two days ago.After updating the database I see that Broome doesn't come up in the system... Is that because no TG's are known/being used yet? I guess I didn't realize you couldn't load them via library imports with just the site/control channels frequencies...
Cortland has their own core, not part of the 2AE core.
Not sure what that means exactly but they are or were slated to be a "member". It was all written out and approved by the politicos but who knows what might have happened in the pursuant years...
The system just online Wednesday and I found the system information via the Unitrunker software. It went offline yesterday late morning but came up today. I reviewed my SDS100 recording from today and was voice traffic between technicians on talkgroup 27403. I believe that right now only the Old State Road site is up and running, based on what the technicians were saying as well as signal strength. They spoke about problems with the microwave link between the County Comm Center and the tower site caused by poorly seated cables. Once they got that repaired one of the techs drove route 12 into Chenango County and there was excellent reception when he was in the Village of Greene.
In case you hadn't seen this document on the Jefferson County System I am sharing it again here as it explains the difference in the relationships of Cortland and Tompkins to the system compared to the other counties.

So being a member doesn't necessarily mean they would be listed even though they utilize the "countywide" TG's?

And other county agencies utilize Cortland TG's for fire/EMS etc?

I see, thank you. I haven't been doing scanner stuff lately so this was all news to me.

Very informative and well explained. Thank you mshumeyk. I'll be delving into this further to help stay "in the loop".

There are several "Regional Interoperable Communications Consortiums" in NYS. These are groups of member counties, independent of any particular technology or system. The Central New York Interoperable Communications Consortium is one of those groups, which includes Broome, Cayuga, Cortland, Jefferson, Lewis, Madison, Oneida, Onondaga, Oswego, and St. Lawrence.
Independent of that you have the Central New York Interoperable Communications Consortium (CNYICC) trunked system, a Motorola ASTRO 25 system with a System ID of 2AE. The system core and master site (the main controller for the entire system) is located in Onondaga County. Seven counties share that core, each with their own simulcast cell (6 UHF and 1 VHF). Those cells are inherently interconnected by virtue of them all running off of the same core. So although it's common for people to refer to each cell as the "Onondaga system" or the "Broome system", in fact they are nothing more than multiple sites (simulcast cells comprised of multiple subsites) of the same single system. One system, multiple sites.
Cortland (SysID 4EB) and Lewis (SysID 70D) counties, while being members of the regional CNY consortium group, are not part of the CNYICC P25 system. They both have independent P25 systems which are likely connected to the 2AE core via ISSI. I don't know the status of any ISSI links between the three systems, someone with direct knowledge of that would have to comment.

I guess that's why it gets a little confusing. If neighboring county agencies have Cortland TG's and vice versa, it would seem they would be part of the same system. Unless said agencies/counties are giving each other radios to use...
Or the radios have multiple systems in them? That's the most obvious answer, and is extremely common. The other possibility is that the systems are interconnected via ISSI, which I've already mentioned in my post.
I must admit my ignorance at not being familiar with the meaning of ISSI. I did easily find information on it and figured there may be others unfamiliar so I thought I would post this. Communication technology has certainly become much more complex since I first started monitoring with tunable VHF Low High receivers in the late 60's just before the first crystal scanners became available.
The Inter-RF Subsystem Interface (ISSI) Gateway provides TIA-standardized network-level communication between Project 25 (P25) radio systems regardless of manufacturer, allows authorized radios to roam between P25 systems, and prevents ID overlaps by assigning temporary unit and group IDs to roaming users.
Thank you for that mshumeyk, more complex indeed.
I was just about to say the same thing about not knowing enough about all of this. ; )

That PDF re: Jefferson County was interesting. Found this quote within it:
I presume the same would apply to Oneida (also VHF)? Unless the subscriber has a dual band radio? "Interoperability", indeed!

So I guess the next question would be, WHY are they not part of the core when when all neighboring counties are? Or does it even matter? Just seems odd...
Another thing, would you be able to receive any or all of the surrounding counties if they were in the same core/system or does that all still depend on your ability to reach neighboring county's signal/tower?
You still have to be in the RF footprint of the county’s towers.
You might hear their talkgroups on another county IF they are provisioned to allow that for that talkgroup AND a radio with that talkgroup selected is affiliated in your county.
You still need to be able to receive the RF from each simulcast cell...there's no magic to it. No different from large statewide systems, or some federal/military systems that have sites all across the country. Of course if particular talkgroups happen to roam across cells, that's a different story, but that is certainly not the norm.
