Hello Jacek, VLF,
Are you really sure? The signal generator is turned off? I can hardly imagine that the signal is so strong. Does the carrier disappear since 22:30 or 23 UTC?
BTW the antenna suddenly dropped. I had the badest thoughts, and still have. It dropped to about 200 mA arround 22:40 UTC. The resonance dropped a bit and the Q was much lower then. A visual inspection showed no sign of a flashover. The PA works well and the system is now prepared for the next EbNaut transmission on 5170 Hz tomorrow, as usual. 
Oh and my tree is back and will monitor that transmission!
I'll continue to check for a fault on the coil now...

73, Stefan

this is from 2.86mHz FFT bins. fft time  only 5.8min!

very good S/N
