Hi Stefan and LF,

Thanks for testing my decoder and for the comments.

Followings your idea, i now use the remai= ning stand-by time of the script to run again the decoder on another freque= ncy (137490 kHz) for the same timeslot XX:00.

Hope is working.
Btw i agree o= n frequency qsy, so please can you ( or Markus) suggest some new frequencie= s for this service ?

Hi Domenico,

Thank you, it works very well.

I made a few mistakes here, 13UTC i have been on a false frequency, 15UTC i had an error in the EbNaut txt file and 16 UTC there was a PTT problem :-)

Now at 17 UTC i am testing something new: One SL instance is only setting the PC clock based on 1PPS+NMEA. I can manually add a 0.3 sec offset in SpecLab, so the PC time is manipulated. The second SL instance transmits EbNaut, as usual, just the setting is changed to 1PPS without NMEA (so the PC time is choosen as the reference). I hope this will now compensate my usual 0.3 second offset, which is very relevant at 1 sec symbol length.

It should be easy to extend the script, just let the decoder run on 137.495, write down the results and then let it run on 137.490, so you can monitor 2 frequencies.
We could also consider to use a separate frequency slot which is below 137.450 kHz. These days it should be possible to afford a separate SL instance just for EbNaut. This helps to avoid interference to other modes like WSPR, OP32 etc..

I hope i can see my message soon, it is exciting :-)

73, Stefan

Yes, your 14.00 UTC transmission has been decoded.

BTW there is also Riccardo IW4DXW attempting to be decoded here and unfortunatly he is trasmitting in the same timeslot.

Yes, this is an issue for the system i.e. no multiple access !

I need to improve the program output. Something like opds printout should be better.

Again tnx for the test Stefan and Riccardo.

Hello Domenico,

many thanks for the great idea. I also made important steps in learning how to deal with EbNaut. As soon as you know how it is done you can build your own scripts and create the functions and services you have done now.

Let's see how it works, i'm sending you a message at 13 UTC!

73, Stefan

Just to rectify my previous message:

parameters for the decoder are:

15 Characters, 1 s /symbol, 8K19A, list=3D20000, CRC=3D16
The actually chosen RX frequency is 137495.000 Hz

the decoder start time is at hour, every hour.

Again,73

Dear LF,

since yesterday i'm testing,=C2=A0 on my ubuntu-PC,=C2=A0 a shell scrip= t 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=3D20000, CRC=3D16
The actually chosen RX frequency is 137495.000 Hz

So, i invite all of you (within my LF reception range)=C2=A0 t= o try lo leave a message on this 'grabber' :

http://www.qsl.net/i/iz7slz/EBNAUT/DECODED.TXT

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.
