Hello VLF,

F= irst of all, congratulations to Stefan, Paul and all OM partecipating at th= ese experiments for the successfull results.

I'm trying to receive some VLF Ebnaut, in Apulia -= South Italy, till now without joy.

Unfortunatly, the remote location at Aunt Melina farm (AMF) , 5 = km away from my city is not yet ready.=C2=A0
In the = same time i'm trying, in my urban usual location, to streaming (locally= ) the audio captured from linux pc using vlfrx-tools utilities.
Vorbis stream sent by vtvorbis is received via lan from Spectru= m Lab on Xp PC. A 42 uHz grabber is running since 3 days now.

I have some question for Paul:

Some advice for the vtblank configuration?=C2=A0

I'm using version 07p.

Yes, a strong signal here and perfect decode of the 3 chars:

=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 H-field=C2=A0 =C2=A0 =C2=A0 =C2= =A0 =C2=A0 =C2=A0E-field=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0E+H= field

Signal phase repeated fine both nights.=C2=A0 Given the S/N of your 2 char<= br> success, you would be very lucky to do 3 chars in one night, but two
nights ought to do it.
