Hello Stefan, VLF,

would a wide-band capture over 24 hours from my QTH/receiver be of some in=
terest=20
for you? If so, I think I could be able to send=A0the results to you by th=
e end of=20
this week or so (hoping batteries last enough :-)).=A0Probably it could ma=
ke sense=20
to share the same .usr file for SpecLab so that to ensure a bit of consist=
ency=20
when comparing figures from different locations.
My sound card support 96KHz sampling at 24 bits/sample, but I found that=
 card's=20
noise looks much better when sampling at 48KHz.

Best regards
Daniele

Hi Daniele,

No problem about the callsign ;-) On VLF you don't even need one for=20
transmitting, hi.

Oh, you are in JN53EM, i haven't known that. The distance is 707 km! This=
 is the=20
3rd best distance at all! Unbelivable, for a antenna in that location, ver=
y=20
fine!!!

I hope cou can improve your RX situation if this is your goal.

And i hope i can transmit more meaningful messages the next time ;-)

73, Stefan/DK7FC
