The new USB soundcard arrived today and I was hopeful it would resolve the problem I am having with WSJT-X. I installed it simply, tested it on PSK and JT65A and then fired up WSJT-X hopefully.
My replies to loud CQs, as before, went unanswered! I am certain that the stations just aren't decoding me. But why? I am decoding others' signals easily.
This evening I completely uninstalled and reinstalled WSJT-X. I think the next step will be to try a different computer. Remembering that I have so far tried two different rigs, two interfaces, two soundcards - the only thing left in common is the computer. But I don't see what the problem should be.
Fascinating, puzzling and a little frustrating in similar measures....but I am sure in the end I shall get it working!
Update! After chatting to Charle M0PZT about it I recorded the signal off air. It didn't decode for me. Listening to the tone direct from the computer it sounded clicky and horrible, regardless of the audio level. This must be why. Now, what to do...
