thanks, that's great news! I was secretly hoping that you might detect the signal, but wasn't very optimistic given the minimalistic radiated power of about one microwatt.
After the tuning correction around 13:50, the current was uninterrupted and constant at 0.17 A until shutdown at 20:40 UT. Interestingly the trace disapperered in Heidelberg around sunset even though the TX was still going steady, so possibly a terminator effect. The phase was identical before and after the retune - thanks to Wolf's GPS-phaselock function, one can even tune around to search for the resonance peak, and thereafter come back to the nominal frequency with the same absolute phase.
The antenna was a litle adventurous this weekend, with a 14 m auxiliary fibre rod pushed slant out of a roof window to hold one of the topload legs and the vertical feed further up. Gave the neighbours reason to stare and chatter during their Sunday promenade ;-).

Coming in nicely here. 11.2dB in 55.5uHz from
14:20 to 19:20.
Was the phase continuous across the interruption?
