Hi Jack

My comments are on the limit case, certainly. And terse. I guess it's a
question of where do you draw the line..

One could argue (successfully I think) that me using a STM32 micro
instead of building our own integrated circuits from sand  constitutes a
closed box. 

Depends I guess on where the definition  line is draw for what
constitutes ham radio.
That's a hard one.
