Jeff, IF shift is practical in multiconversion receivers, but the K2 is a single conversion design (for fewer spurs, better dynamic range and better IMD). To implement IF shift in a single conversion receiver would mean changing the BFO in sync with the VFO - and that is not an easy feat. It might be practical in a one-band, one sideband receiver, but I don't think you would want to sacrifice your multiband K2 just to have IF shift. If you wish to extend the principle to both sidebands or to additional bands, the scheme gets complex. Yes, a larger microprocessor could possibly do that, but there are other requests for added functions when (and if) more storage space is available - due to the complexity of IF shift in a single conversion design, I would believe that is WAY down on Wayne's list of 'things to do'.
