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,  
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 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.
  
73, Stefan
