Chas--I followed your advice and the frequency moved. So I am now using an O-scope probe to convey the signal at 10X attenuation. The trimmer still makes no difference, but it was interesting to see what I assume is decoupling the generator's internal capacitance from the IF transformer via the increase in series resistance.
