Fantastic achievement! Congratulations to Stefan and Andrew!
Very high Eb/No for this distance!

PS: The RX at RC4HAA is a 100m long wire with a passive RC filter andan
isolation transformer, i.e. no preamp is used. So it is a pure Efield RX
hanging in the middle of a city with a population of > 1million people.

I am glad to report about the successful decode of my 1 characterEbNaut message
on the VLF RX site at RC4HAA.
This is a land path distance of 2877 km,
So far the best DX between Germany and Russia below 9 kHz.
It is my new personal ODX on VLF (the old ODX was just 4 km shorter).
A screenshot of the decoder result as well as the log file is attached.The
unexpected good SNR suggests that even longer messages are possiblewithin a
single night. Also we need to consider that it was a verynoisy night again,
with thunderstorms in Spain and Italy.
A new message announcement will follow soon, next time i'm trying 2characters.
