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.  ;^(
