Many thanks Domenico.

I think that i found the bug in my configuration now!
Let me try another attempt and let's see the offset:

f = 137.53 kHz

Symbol period: 1 s
Characters: 15

Hello Stefan,

Here's my decode also.

Found best results at same freq. offset of Riccardo.

The small phase change is due to propagation.

Thanks for the signal and thanks for your calculation of my 'silence' period after op32 transmission, that gives me possibility to receive you.

Hello Riccardo,

Many thanks for the decode! I would assume that the phase rotation is due to propagation. There is also QSB on LF, although not as strong as on MF. The Alps may add a bit more.

Hi Stefan, Markus, Domenico, LF

Vy strong here (as usual) in JN64bw, dr Stefan.
Good decode: there is only a little phase rotation and I see you about
6.3mHz lower than your nominal QRG.

All the best

p.s.: congrats for your efforts and fantastic results in VLF activity.
Keep up the good work!
