I'm looking forward to when we find some common piece of hardware like this that can also transmit.

I wouldn't be surprised if this turns out to be the first crack in opening this modem further and finding the transmit functions.

After all, a modem has to be able to send as well as receive, and a transmit-arbitrary-IQ-samples function would be useful for calibration at manufacture time.

If you want to do that you can grab a PlutoSDR for ~$150 and supports gnuradio right out of the box.

That said the post was a tour-de-force in cross functional engineering, truly impressive stuff.
