Thanks Allison. I forgot about the K2 and will check the schematic when I return home. One nice thing about the old MXM circuit was that it was continuously variable rather than the step system used in the K2. Both work beautifully. I was thinking that the continuous shift might work, until I went back to read your comment about adjusting the BFO as well. I should have realized that if there was a simple solution, someone would have done it already. Life is never quite as simple as I would like it to be and my self-taught electronics instructor is nearly always behind the curve.
