Thanks to Markus, Stefan and Bernd.
Well, Markus: the feedback is connected to the "L" (or "I" signal toward SDR) output channel. After a "perturbation", the system re-locks the phase in a few of seconds, but seems to lose the nominal phase reference.

Update 25 Sept. 16:00UTC:
With Domenico (thanks Dom!), we held a quick exchange of views and he told me to check the "GPS phase lock" flag, which was effectively disabled and now enabled.
I'm transmitting for a new test with the same EbNaut parameters every a half of hour (started at 16:30 UTC).


All the best

Hi Riccardo,

here a screenshot:

 

 

The glitch is nearly in every file at different positions.

If you are interested, I could send you the files.

Hi Riccardo,

Please, Stefan: how many times have you seen that glitches on your decodes?

No so many, maybe once per hour. I don't know the exact number.
On one transmission it looked like you lost the frequency lock, the phase was very unstable. I think it is unlikely that it is propagation. Sorry, i already deleted the txt and wav files after getting the results. Maybe Bernd/DF9RB can show you a screencapture of showrawsyms...


About VLF, in the next days I will schedule some transmissions.

That is very apprechiated.


P.S.: Congrats Stefan (and Edgar) for your great achievements @ 17470.1 Hz!

Thank you. Soon there may be a new success to report. The stack is developing positively.

73, Stefan
