[Elecraft] XG3 Calibration from 10MHz Standard?

[Don Wilhelm]

If you do not have a frequency counter, there is another way.
Use XG3 Utility to set the XG3 to provide a 10 MHz output.
Listen to the 10 MHz reference in your receiver in CW mode and peak the 
signal at your sidetone pitch.  Then listen to the XG3 without touching 
the receiver.  Adjust the XG3 software parameters to produce a signal at 
*exactly* the same sidetone pitch.
