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 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?
