Dear LF,

since yesterday i'm testing,  on my ubuntu-PC,  a shell script that pipes some vlfrx-tools and ebnaut linux programs.
This script (see attached) permits to achieve an automatic EbNaut decode from the audio coming from my LF receiver. The decoder is setted with these parameters:
16 Characters, 1 s /symbol, 8k19A, list=20000, CRC=16
The actually chosen RX frequency is 137495.000 Hz

So, i invite all of you (within my LF reception range)  to try lo leave a message on this 'grabber' :

Of course, i'm at disposal to change these settings for any schedule.

These are the programs running on PC:

- vtcard, vttime for manage the audio card and timing;
- gpsd, ntpd for getting utc synchro from GPS (that has nmea + 1pps)
- vtwrite to store the raw audio on HD
- vtread,vtblank,...ebnaut (are launched by the script)
- wput for upload the DETECTED file

This is the occasion to thanks Paul Nicholson for his programs.

OK. Many things need to be improved on this idea. Your suggestions are welcome !

73 and FB summer to all.

Domenico, IZ7SLZ
