Hi Jim
 
OK too bad you can't resolve it with your existing Sound Card.
 
When considering a USB SC think about SDR (the future of Ham Radio).= M-Audio is considered a good card but see M0KGK's site for comparison wit= h the Creative Labs Sound Blaster Live a cost effective solution (these ar= e still available although production I believe has now ceased).
 
Oh BTW double side band WSPR dosn't bother me in the least....hee.

Please observe the reports I am getting from Jim G7NK= S WSPR transmissions :-

 

First a weak one and then a strong one then a weak on= e (see below) does it mean there's a sprog / modulation on Jim's tran= smission off set by approximately +/-50c/s? I will try to get a time domai= n display of it when I have time, it may provide a clue. Is it my RX?
