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
  <br>
about 1.3 dB short of decoding it.  Quite a challenge
