Hi Eddie,

Indeed, it looks like you've got it! A first detection from the fixed 
antenna, as you say. Congratulations!
The average SNR is in the order of 6...8 dB in 47 uHz i would guess.
In the 'wideband' window it looks like there is a low pass filter, 
already affecting 8.27 kHz. Is it the antenna schematic that i used for 
ELF, ZEVS, Schumann? Can you send me the schematic details?

If you can gain another 6 dB SNR, which could be realistic, then we 
could try EbNaut on VLF. I guess that's a new field of operation for 
you. Would you like to participate?
These days i'm attempting to leave EbNaut decodes at RN3AUS. You could 
try to join in there.

I looked on Pauls grabber and saw that the SNR is not worse at night, N 
and S is higher.

Yes, the safety function was triggered last night due to heavy rainfall 
(must have been), so the transmission stopped. Maybe it was not 
necessary but maybe it saved the coil from a fault, who knows?! I should 
have made QSY in the morning but never mind.

BTW the recent 2 character message (attempt to be decoded in Moscow, 
result willl be known tomorrow!) was also decoded at SQ5BPF in Warsaw, 
that's already > 900 km. We are in abt 650 km distance?

73, Stefan
