The point of this is that some imagined expert in the mathematics of SDR
radios might believe he knows the theory of operation of them, but
couldn't find weak-signal CW DX with it, or even more relevant, work that
DX.

That does raise one query with me about the implementaions, because I'm not
aware
of an ADC that will yield 1 uVolt signals as any reasonable number of bits?
