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

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

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.
