The phase and amplitude plots are showing clear diurnal signals
so it looks as if it's mother nature rather than the oscillator
causing the major variations. I'd like to get a 3 day mean of these
plots. Thanks Markus, Paul and Andy.
Edgar - that little peak was exciting enough for me to try
again, so if your willing to take a look, please do. The
TX will be on again tonight.

The 13:45 and 14:00 frames have a peak in the same place
as the 10:15 the previous day.

Such a small peak is mathematically insignificant though
but we might take it as a hint that a signal is lurking.
Edgar have you any way to check that the frequency is
properly locked to GPS? If it's not locked the VO1NA
signal will be smeared out.
