If anyone wants to work on such project. Can I give a pointer into the Pluto sdr platform
for the receiving ends?
Don't need to redo the week as the whole device run linux, have in fact 2 tx and 2 rx
ports and it can support USB ethernet d'ongle for inter connection locally. They go up
to 6ghz.
Might be a nice radio to play with and you can set a high powe amplifier at the tx port
and have a separate antenna for rx and put a preamp in line for higher performance on the
ham bands part of 5 ghz.

Having two links with monitoring and metrics may be an

for propagation checking :-) We must also set up routing priorities in
relation with link quality. But that's another topic :-)
A proposal to set up such a system and publish measured results is the
kind of potential improvement in our collective understanding of
atmospheric effects and impact on SHF digital links could be an
interesting grant request.
Anyway, that's what I was fearing : we are in the
SHF domain, we cant'
just put some UBNT stuff on the highest point and see if it works, but
we need real SHF experts in the team.
Yes. I learned this the hard way myself when I was young and naive, and
thought I could change the world setting up some "easy" mountaintop 10
GHz data links...
