This is really for my own sake and probably not useful to others. Some geekery around local ham repeaters.
Signal reports are from a discone in my attic. Coverage predictions are from Radio Mobile Online, and bake in a whole lot of assumptions for something I generally don't have many details for, so don't take them with any seriousness.
Boston, 145.23
-105 dBm or so. A close-in hill leaves the signal a lot weaker here than it would otherwise be.
