Using HF as proof of concept for advanced, software-based local digital comms

I think I found what I was looking for for a proof of concept using HF
for local digital communications using the amazing sound card-based
modem / protocol / networking software that's now out there.

I guess I'd seen it antecdotally, and yes, some of you had said this
to me... but I didn't really grasp that QRP was where all the radio
hardware experimenters have gone. MAN there's a lot of neat stuff out
there for QRP! And so much of it looks simple and elegant, and SO
reasonably priced!

After doing a fair amount of surface mount work over the past 18
months, this stuff looks EASY!

Now if someone could just do much the same thing in a 10m or 6m radio.
I'm kind of giving up on the idea of radios like this for 144, 222, or

But guess that's what the POC is for.
