Brett, that quote was from N6WG, not me.

However, i.f. shift such as other rigs often feature require a
multiple-conversion design with all the issues that come with
additional
mixers, oscillators and complexity. "
Well, I'm not sure this is totally true. Before I got my first
K2, I used a
Kenwood TS-180S which had a very nice IF shift feature. It was
also a
single conversion radio, with an IF of about 8.3 MHz. I loaned
the manual
to Eric and Wayne so they could see how it was done.
Sure wish there was a way to implement it in the K2.
TS-820S is another example of single conversion with IF shift.
You can do with K2, but bit too granular with current front panel
interface. I believe it is even mentioned in the manual.
Making a knob into interface for IF shift is entirely possible,
since knobs are already used as interface to change
frequencies of stuff inside.
"Firmware says no" (apologies to Little Britain ;^)
Saying it can't be done & not appreciating what IF shift
is good for probably helps keep it that way. ;^(
