I'm not sure I understand your question.
The SG-8 is not really designed to generate a frequency modulated carrier. It should generate an amplitude modulated carrier w/a 400 cy tone.
How do you know that it's not changing frequency? Is the the tuning cap moving when the tuning knob is turned?
I take it that you are trying to see what it's doing with a scope? If so hook the generator to a receiver and listen for it. It's NOT a precision device so you will have to tune around a bit near the frequency the dial sez to find the signal.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
