[Elecraft] K3 & ADAT ADT-200A by HB9CBU

Hi,

I, too, would be very interested in seeing how "entire HF spectrum digitized
at once" receivers would fare in the real world. I am *very* skeptical.
Although the Perseus (with that architecture) receiver fares relatively well
in the recent ARRL test, the testing completely ignores what happens when
there are not *two* but thousands of strong signals in the passband. With
this new architecture, it's imperative that ARRL and other labs find other
ways of evaluating real world performance as a simple two-tone test becomes
completely irrelevant.
