LF: Re: WSPR does not work

["James Moritz" <james.moritz@btopenworld.com>]

Dear Andrey, LF Group,

It certainly looks like you have WSPR set up correctly. There are not many 
settings to get wrong. The signals from DF6NM are fairly weak, but my 
experience is you should get at least some decodes when the signals are 
visible on the spectrogram like that. However, other people have also had 
trouble decoding WSPR signals at LF and HF, and there seems to be problems 
with some PCs and sound cards that fail to decode weak signals. My 
suggestions would be:
-Try the "QSO version" of WSPR in WSJT 7 - some people have had more success 
with that. It will decode beacon signals OK, but only one signal at a time, 
I think.
-Try running WSPR on a different PC, if you have access to one.

Hope that is helpful - good luck!

Cheers, Jim Moritz
