If what you say about the real close in performance is true, Bob
(and I have no reason to believe its not), I am surprised that nobody
has tried using the SDR-1000 as the IF of a superhetrodyne receiver
with tight filters and high intercept point mixers. Seems like that has
the possibility of yielding a receiver that is a notch above even the
Orion (the sub-receiver could be a standard direction conversion
architecture like the SDR-1000 for supplying general coverage and
the pan-adapter function).
