...i decided to delay the start of the transmission to 08:00 UTC.
Maybe this gives a better phase stability over the path and
transmission period.

There was an interruption of the carrier between 5:28...5:48 UTC. This
was again by reaching the -20 mA safety limit. It was just due to rain
which pulled the resonance to much downwards, despite the phase meter
driven transductor which can compensate a drift of up to about 25 Hz in
this frequency range.
A few more interruptions and phase reversals are shown on the tree
grabber but these were only on the RX side, a restart of the Raspi was
done after 2 months of errorless operation.
A second attempt of the longer message:
f = 6470.100000 Hz
