Wouldn't it be easier to use a frequency counter? If one is not
available, but a general coverage HF receiver or transceiver with a digital readout is available, you could zero beat the oscillator, note the reading on the display, cause the oscillator to shift to your other frequency, zero beat that signal, note the display reading and subtract to find the difference in frequency.

How can I measure the frequency deviation / pull of the crystal with the series configuration? Any ideas? If you have another crystal, build a second oscillator. Run the two into a mixer followed by a simple lowpass filter, and measure the resulting difference frequency. Roy Lewallen, W7EL |
