It'll be interesting to see the eventual application of this to moon bounce. If they put it on a sufficiently stiff backplane, and calibrate things carefully, the 240 channel system they hint at looks like it might be able to pull it off.

Personally, I'd like to have a coherent SDR transceiver for HF/VHF that I can expand arbitrarily, and doesn't cost multiple thousands of dollars.

Nice project! Would be nice to have an option without a Rapsberry Pi 5 though - I think a decent fraction of your audience already has one and maybe doesn’t want to pay for another

Am I right in thinking from the comparisons this only works at 4.9 to 6.0 GHz?
