You can see that the file named 0= 4242231 by SL is reported by EbNaut as starting at 22:26 and suposed to contain a record of 10 minute= s, so ending at 22:36 So it may contain just a fraction of Domenico's message, which started at 2= 2:30 untill 22:40 aprox Is that right ?

Thank you for the signal Domenico=
 
Unfortunately no decode, but this= helped me to identify some problems here in my Rx
First is the VAC problem. What I = get from 11.904 Alpha at 3.5mHz FFT is a bunch of carriers
as you can see in my grabber (scr= oll down to VLF screen)
 
Getting the stronger carrier as r= eference I calibrated SL sample rate. The result is probably<= /div>
acceptable, as I have got some pe= aks from Domenico's signal at the right time slots
This were observed using Show_ram= sys. But the peak is wide and not a sharp mark as shown
in the examples provided by Marku= s, which have been my routing map (thank you !)
 
I think the best file is 04242231= and produced this graphic in Show_ramsys
 
Using some frequency shift in the= decoder I got the peak almost centered
 
But the decoder produced no messa= ge
 
This peaks can only be seen in th= e files with FFT recoded at time slots xx:00 and xx:30
And even not in all the files but= just five. The converted wav can be found here if there is interest in squ= izzing it
 
There is also a problem with the = time of the recordings. I'm not getting the records at the exact hour
and don't know how to configure i= t in SL. You can see that the file named 04242231 by SL is reported<= /span>
by EbNaut as starting at 22:26 an= d suposed to contain a record of 10 minutes, so ending at 22:36
&= nbsp;
So it may contain just a fra= ction of Domenico's message, which started at 22:30 untill 22:40 aprox
Is that right ? How can I manage = to get the FFT files recorded at the right time ?
