I think they call it "tunneling" VHF and UHF under the right assumption m atmospheric conditions can bounce and go longer distances depending on terrain and such. Might be an option. Does it happen at sunset or sunrise or directly between the two?

Seems like 3-4AM. A duct is very possible. I just didnt know a duct would carry a signal of that high a frequency. I have seen ducting on 2m (144mhz) often and I saw 70cm (440-460mhz) ducts once or twice. From what I understand, the higher the frequency, the less likely a duct is to form capable of carrying it.

Or someone has the wrong GPS coordinates in their mesh location and are closer. I'm not sure if that is possible. Or maybe they have directional antenna on hill top. Radio waves are pretty interesting.

I'm not totally sure about that only because there were four nodes that were of similar distance away.
