Ok, Stefan, thanks. I'm ready:
Start at 00:00 UTC (5 Oct) Coding 16K21A CRC 16 20 sec/sym 6 char Duration 6 h, 24 min
...hoping the noise remains low.

Hi Riccardo,
now i switched to the N-S loop in the 424 uHz window. It may give the
best result in the spectrogram.
If you like to try a message, don't hesitate :-)

Hi Stefan, VLF
Thanks, Stefan! It's a good news for me.
Unfortunately tonite I can't mantain a good antenna
current, now it's slightly oscillating around 525 mA. Anyway, I'm still
on air with a continuous carrier.
Thanks again and have a good night.
All the best

Hi Riccardo,
The noise at night has not been unusual high. Today it was very quiet
in daytime however. Ich searched for your signal in daytime, from
6...16 UTC:
N-S loop: 15.45 dB in 27.9 uHz
E-W loop: 4.52 dB in 27.9 uHz
E field: 6.98 dB in 27.9 uHz
...so the signal is there, on the N_S loop. I will try to combine the
signals to form a cardioid into your direction but my PC is very slow.
So this is just a first positive feedback for tonite.
I'm sure it would work to decode your callsign or another message with
the same length...
Thanks for the signal, useful for learning...

Yes, Stefan: I'm still on air.
My working conditions are the same they were in
my
last VLF transmissions (7-13 May). How about noise?
Thanks for report.

Ciao
Riccardo,
Thanks for the signal.
Somehow i did not see it on my grabber.
I analysed 6 hours starting 21 UTC, for the N-S loop and the E field
(separately) but i don't get a significant SNR.
Did you actually transmit during that time, i.e. went all well?
