Hi Luis,

I have to laugh. Pascal is now quite in trouble, his RX site is highly requested on all really low bands. Just 2 days ago i started to ask him if he is interested to build up something for VLF. Maybe this triggered his idea to try LF first?
He did already download SpecLab and even vlfrx-tools. I will advise how to build up the software and settings... There is much work to do it seems :-)

I agree with Alex, that path is not really easy on LF in this time of the year. But i remember the time where RN3AUS has been in UGANDA, see http://rn3aus.narod.ru/uganda/index.html. Uganda is on the way at least...

But on 17 kHz maybe? Or even 8.27 kHz ? That's my challenge...

73, Stefan

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.
73,
Pascal (FR5DH)
