There's quite a few PDs around you that are using P-25, Steve. Don't be surprised when you hear them. Unfortunately, most of those PDs go encrypted when they use P-25. But not always.
Not sure how the modern-day receivers handle encrypted P-25. Unidens used to mute the audio. I'm not sure what your model does. Bill, do you know? Other manufacturers didn't mute it and just let the R2D2 noise of encrypted comms through. I'm sure you'll figure it out.
Last time I was there, Stowe PD was P-25 capable. As was every PD in the Burlington metro area. And Orange Co. sheriff. I think Washington Co. sheriff may be, too. And lots of PDs in New Hampshire, as well as the NH state police. And we won't even get into all the P-25 coming from Quebec and Ontario.
Happy listening!
