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 :-)

    <div bgcolor="#ffffff" text="#000000">Hi Riccardo, <br>
    <br>
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:<br>
N-S loop: 15.45 dB in 27.9 uHz<br>
E-W loop: 4.52 dB in 27.9 uHz<br>
E field: 6.98 dB in 27.9 uHz<br>
...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.<br>
I'm sure it would work to decode your callsign or another message with
the same length...<br>
    <br>
Thanks for the signal, useful for learning...<br>
