VLF,

I'm trying another 8 character message, just to get a clear decode from Alex. Of course all reports are welcome, as usual :-)
The message has started to late again but not as late as the last one, so maybe there will be a clear decode. On the other side there is more QRN now. Some day we will need a tool for stacking/ combining multiple wav files under windows! It would make things easy on that path.

Now:

f = 8270.100000 Hz
Start time: Tuesday 07.Mar.2017   22:20:00.3
Symbol period: 30 s
Characters: 8
CRC bits: 16
Coding 16K21A
Duration: 11h, 12m, 0s
Antenna current: 700 mA

Based on the last carrier S/N of Alex' last decode this could be the result: http://abelian.org/ebnaut/calc.php?sndb=15.87&snbws=0.000035&snmps=&code=16K21&sp=30&crc=16&nc=8&submit=Calculate
But some hours will fall into daylight, so it will be quite close to the limit again! :-)

73, Stefan
