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 interesting tool 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...
