Yes, I am in Schoharie Co and I often hear them say "go to digital". They use it briefly just for private conversations instead of cell phones. I bought 2 digital scanners (106/197) and this "digital" signal cant be listened to. Whenever they say to go to digital I do hear an obnoxious sound on certain freqa that I have programmed in for municipalities. A couple of them in the 154. range and a few in 159. range.
One for certain is 154.310. Cant remember the other exact freqs. Finally, I just locked those freqs out as the noise is unbearable. I did talk privately with someone on this forum and asked him why my digitals wouldnt work and he explained the set-up that Schoharie Co is using just cannot be picked up by digital scanners. Maybe he will chime in more.
Side note: Their other private channel they use is 156.210. They refer to it as "channel 13". You need to be close to hear it though. By the way, someone had PM'd me and said 156.210 is impossible as its not licensed to them...Cant help with that, but I know they use it. Fact.
