Thanks Paul for the measurements. Hmm, it's a bit
disappointing, especially as I don't know the cause for the variation. From
here, it appeared that the PLL was nicely in lock every time I
looked, and the traces on the grabbers looked mostly good. For the next
transmission I will have to go find an independent means of monitoring
the radiated phase.
All the best,
Markus (DF6NM)

The phase doesn't look very steady Markus.
Below are
10 minute averages, stepping 5 mins and
the timestamp is the start time of
each window.
