Hi Paul, VLF,
I have prepared my transmit site so i can run permanent transmissions
now! Also the antenna current meter has been re-calibrated (actually no
re-adjustment was necessary).
Just in case the extreme QRN will stop in the morning, i will run a new
transmission:
f = 6470.00000 Hz
Start time: 12.05.2016 00:00:02 UTC
Symbol length: 100 s
Characters: 3
CRC 16
Coding 8K19A
Duration: 11h, 33m, 20s
Antenna current: 200 mA
Maybe this one will work better. And, to be honest, in the last
transmissions the antenna current fell to about 170 mA after some time
because the coils sagged a bit into each other due to the heat. But now
this process should have stopped and the resonance was re-adjusted. I
can measure a stable 205 mA now during the time of the observation.
73, Stefan

Yes, still working on the 19 char message. I think I'm
about 1.3 dB short of decoding it. Quite a challenge
because overnight 7th/8th was very noisy.

The last few nights have been quiet. Typical!
