Hello all,
Found the problem
. I have been using my Heathkit SG-8. Terribly convenient but one thing I have never liked about it was the harmonic rich output waveform. Did as suggested and scoped the IF and calculated the frequency. Looks like my SG-8 has more 460 khz in it at 230 khz than it does at 460 khz. I am very happy to have sorted this out and thank all of you for your patience. I need to dig out my other signal generator, a Philco 077. It is a lot bigger but has a much nicer wave form. A little more period correct also.
In any case, more by accident than intent, my IF is peaked at 460 khz.
