But if instead of that VCO we have a VFO that is first manually tuned very near the
target frequency,
So it seems the Huff and Puff method is for providing the final little bit of frequency stabilization to a VFO that is already adjusted to oscillate very close to the desired frequency. Would the Huff and Puff method be one of the preferred ways to fine adjust the frequency of a 10mhz crystal oscillator to make a DIY GPS disciplined frequency reference?
