In actuality I haven't heard this at my QTH yet. It should have good coverage, though:

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.

http://web.archive.org/web/20010124070500/http://www.barc.org/barc/repeater.html had a lot more information than the current site.
