Calibrated signal generator at harmonics

Even the XG2 manual mentions that the circuit produces useful harmonics at predefined levels. Using the 14.000 MHz XTAL and the IC706MKiiG as a test instrument I recorded the following:
  1. 14 MHz: S9
  2. 28 MHz: S8
  3. 42 MHz: S6
  4. 56 MHz: S3
  5. 70 MHz: no signal, barely audible
I cross-checked 2nd and 3rd harmonic readings with FT-817 too.
