Be patient. Broome County held a major press conference in January 2019 announcing the new P25 trunked system, promising it would be in use in two years, or at least in 2021. The first sites just went online last month, and the last tower site was just completed a couple of months ago.
On the Tioga County website a there is a request for proposals for communications structure construction from August 2021, which probably is for the radio system sites. It will be a while.
If you haven't seen the consultant report from 2018 for the county, I have added the link below. The final pages are a table of the necessity and desirability of various features. You'll note that "Trunking" and "P25 Phase2" are deemed "not necessary or desirable". It is a good thing they didn't follow those recommendations. Joining CNYICC makes a lot of sense, as there is a significant amount of mutual aid between Tioga and Broome along the Route 86/434/17C, 38B and 79 corridors.
