Thanks Uwe. The late evening may not be ideal in terms of QRN background but let's try anyway. I have pushed out the antenna again (half height due to wind), and restarted the VLF grabbers with EbNaut recording since19 UT. 8270.000 is still within EbNaut's bandwidth (+-1/40 Hz) of your QRG so I hope that my new VLF neighbour Roland won't fire up tonight.
All the best,
Markus (DF6NM)

the carrier is on the air.
there will be a special message for Markus:
start 22:00:00
coding 8K19A
CRC 16
period 40
length 2
duration 04:05:20:00
Have fun
Uwe/dj8wx

PS. rain would stop the transmission automatically.

Yesterday afternoon the noise was fairly moderate, and around 18 UT I caught a good dash in 63 uHz, presumably from DJ8WX. I then attempted simulated EbNaut decodes on the carrier, using 1 and 2 character settings and 40 s symbols. Both resulted in valid asterisk messages, with some more margin to spare for the single character. So far I have never decoded a real message on VLF, and I'd be keen to try...
 
Best 73,
Markus (DF6NM)
