To answer your last question, PA3AKE has published 3rd Order Dynamic Range
data with both signals in the passband of the roofing filter of a homebrewed
receiver's front end. You might like to look at his website. In my
experience when working 40m SSB DX zero beat with a BC station's carrier,
maintaining a large in- passband receiver dynamic range helps a lot.

Would not it be nice... if someone measured the IMD dynamic range of the
K3 with the interfering signals placed within the bandwidth of the first
IF (roofing) filter?
Or has that one already been published somewhere? Or is that impossible
to measure?
