That's possible, but I'm not sure it explains how the strength of the
spur varies linearly with the input signal strength. Perhaps the
AGC maintains a constant signal level at the stage generating the spur,
but I'd have to think about it. I still think the most likely cause is
some leakage of an oscillator harmonic into a mixer somewhere.
Still waiting for K7JA to return my call.
