Hi Markus,
Thank-you for the good news and the high resolution service. The keying
sidebands are quite clear on your spectra.
Tracking the 2.8 mHz offset has been challenging. It seems to be due to
a rounding error. Your grabber is a convenient way to monitor progress
towards correcting this.
I believe the phase incoherence of the previous exciter was caused by
gating the oscillator before the divider stage.

Joe,
good coherent traces from VO1NA have been visible here through the last six
nights. The close-in spectrogram looks just perfect, with textbook-style
symmetrical modulation sidebands at +- 16.67 milliHz
