Despite the strong QRN there is alreday the next success. The 2 character message from last night was decoded on the RC4HAA VLF RX site.
A capture and the log file from the decode is attached.

Based on the SNR of the first successful message decode, 13 dB in 23 uHz, it should be possible to transfer even 3 characters in a single night. It will be close to the limit but let's try for tonite:

f = 8270.1000 Hz
Start time: 07.November.2017  16:00:00 UTC
Symbol period: 60 s
Characters: 3
CRC bits: 9
Coding 16K21A
Duration: 12:32
Antenna current: 620 mA
