LoRa testing today. Last time there were some significant obstructions and range was limited to 1.25km. Today was all about clear line-of-sight. The base was placed high up on a mountain. The rover went to two smaller mountains.
The base station: Base set super low to the ground on mountain top to avoid detection by passersby and to try to avoid theft. It didn't rain the whole day, but for a few hours it was raining pretty good. RS units are definitely waterproof.
Now we head off and bring the rover to mountain 1: Rover hand-centered over "brass bolt" embedded in concrete pier. Rocks used to stabilize the RS against the wind. 16.5km baseline! Impressive! Way to go LoRa!
OK, off to mountain 2 now:
RS rover can be seen on tripod in the background. Center of picture, a little east of north.
Now we’re talking! 19.2km baseline! That was beyond my expectations!

In conclusion: a great day; the LoRa radios performed extremely well. :thumbsup::+1:
