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

Hello VLF group and RC4HAA team,
I am glad to report about the successful decode of my 1 character
EbNaut message on the VLF RX site at RC4HAA.
This is a land path distance of 2877 km,
http://k7fry.com/grid/?qth=JN49IK00&from=LO53CF34
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 possible
within a single night. Also we need to consider that it was a very
noisy night again, with thunderstorms in Spain and Italy.
A new message announcement will follow soon, next time i'm trying 2
characters.
