Uhf
There are several individual companies that have acquired their own channels, mostly on VHF but a few on UHF.
The most recent I have noted are Franklin and Sidney on UHF, Hancock has UHF but I have yet to monitor its use. There are many other departments that have gone to VHF for individual operations over several years Delhi, Downsville, Stamford, Grand Gorge, Hobart, Andes, Bovina, Bloomville, Walton, and the Margaretville area (appears to be a district channel, have not personally monitored it).
The new UHF for Sidney and Franklin seem to make sense given the frequent mutual aid with other UHF-capable departments (Oneonta, Otego, and Chenango County).
