Hi Pascal

 

DFCW is just slow CW like QRSS. But the length of dot and dashes is the same. DF states for dual frequency

So dots and dashes appear in a spectrogram slightly shifted in frequency. It is a slow mode to be read in a spectrogram

No software needed to decode that, just can ve viewed in a slow spectrogram

 

May be you would like to share your spectrograms in real time. If you are interested in setup a grabber

I can help you. We can exchange the details in private mail if you want

Hello Alex, Luis, LF,

Thanks for your answer,
I do not have software for DFCW with Linux Debian on my PC. Just wsjtx actually.

I'll be back on wspr MF tonight.
