For what it's worth...a friend of mine works for the state park and/or forest commission (or whatever they are called...I am new to VT). Last week they had their (VHF?) base radio, coax, and antenna removed and they just got new HTs. From the description of the antennae, they are UHF. So far they have only tested the radios and have used just two channels, one of which sounds like it's repeaterized (two parties could hear each other easily when miles apart), and one of which seems to be simplex (same two persons could only hear each other when closer together). I know it is difficult to extract information from people who aren't radio hobbyists but I did my best. I hope to have a look at the HTs sometime soon.
