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...

73, Stefan

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