Since it has been difficult to find an accurate map of the repeaters located in the U.P., especially since even the entries in the ARRL
Repeater Directory have been inaccurate, I am publishing this map, which is the most accurate map available on the Internet at this time (October 2011).
Since I travel quite a bit, I am aware of some repeaters in the U.P. that are not published, and I even made telephone calls to friends from either
end of the U.P. in an attempt to confirm frequencies and to present the most accurate information that I can to my fellow "Yooper" hams. I will update
this map as I come across more information.
