Re: LF: EbNaut attempt at 137495 kHz

Ciao Riccardo and all,

many thanks for your signal that is giving me the opportunity for reactivate the auto-decoder

http://qsl.net/iz7slz/

Your 21:00 UT transmission has been decoded (see attachment) !
 
The decoder (as you know, i call it "ambaradan") is based on some linux modules from the fb vlfrx-tools of Paul Nicholson.

There are two time slots programmed. So there is the opportunity for other operators (in my receiving range)  to test this equipment.

Updating of the post-decode plots images sometimes fails.

I'm still investigating...seems a cache issue on server qsl.net.

UTC syncronization is given here by the  program 'chrony' that claims to work better than 'ntpd' when using 1PPS.

Of course the program 'vtwrite' is recording, hoping to catch a signal from Rob K3RWR (cross-finger) on his new QRG.
