[Ground-station] MUD 2024 - call for speaker support and advice

Yes, that was what I suspected, I have not started building it yet, and
that will likely take a while. It may need some kind of GPS locking input,
which is probably getting out of scope for the original project, but I am
interested in having a standalone microwave radio rather than depending on
an entire IF rig and connecting it etc. Just one box which you plug into an
antenna and power supply, like a normal radio :)

I love the idea of a hackable radio generally, where we're not dependent on
some proprietary & complex commercial product. This seems to be kind of
missing in amateur radio currently, outside of SDR products?

As usual, I have a long list of projects to complete before getting to any
of this, so don't be surprised if it takes a while to get anywhere.
