My home node made contact with what I think was someone flying by with a RAK module. The GPS put it at a distance of 47 miles and height of 36,000 feet, along the path airlines would take from New Orleans to Houston.
I’ve had contacts with more distant nodes but this one was able to confirm receipt and I got a valid traceroute back.
Let us know how it turns out. I’m sure they’ll be some signal reduction, but 33cm wavelengths will still be able to escape.
