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.

I seem to live in a bit of a null...
