Very cool project.  And I love the last shot that shows the interior of the cabinet.  Almost nothing there but that not-very-large TQFP package.  Compare that with TUs from the days of old !

I am sending out some bare boards for my DSP TU project today. I have six
more of the latest revision that fits in a plastic box (see
https://w6iwi.org/rtty/DspTU3/ ). If you can make use of it, I'll send you
a main PCB, a front panel PCB, and a real panel PCB. I also have some rev
B boards for when I run out of rev C.

Let me know if you'd like one!
