So, you seem to be indicating that my link to N0CFM-CARBBN-GRNMTN is OK (when the radio is up, literally on top of my flagpole, which it's not currently...), but beyond that it's not.
It's sounding like the Green Mountain node is a common denominator for a few people (from other posts), yet its link is not so great to others? I don't see "W9RIK-QTH-1" in the screen shot I posted. Am I just "blind" or are you referencing something else for that evaluation? What is considered a "usable" ETX?
Is a map of the physical locations of these nodes available?
