Right on point, Paul.
Kenwood makes a big deal of the down conversion on its brochure, and did
so at Dayton, and etc. It does not make it all that clear the down
conversion is limited to specific bands.
You get it. Your post addresses my concern exactly.

It's there. Sort of. See the graph on p. 3 of the TS-590 brochure:
Note that Kenwood claims 2 kHz DR (500Hz, preamp off) in excess of 107 dB.
Pretty extraordinary right? But note that the claim is on 20m where a
down-conversion scheme to 11 MHz is used. What about WARC and 10m? If
those bands are using up-conversion, then there will likely be a big
disparity in attainable DR across bands. The TS-590's down-conversion
scheme is optimized where contesters need it most.
By contrast, the Eagle's design should result in reasonably uniform DR
across HF bands, at least through 10m. Hopefully, Sherwood, QST, and RadCom
are ready to spend more band-by-band time with their measurements because
the variation in results is going to be very interesting.
