After spending £2.19 I still can’t get WSJT-X to work!

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…

    If you have CB SWR bridge, or something that shows you are actually putting RF up the pipe, I’d try that first.

    Look at the antenna connection. Clean and no moisture, check the antenna also. Then work your way down, check the coax, look for rips and etc. Check back of the rig, nice tight connection. If all else fails, break out the ole straight key and call cq on 7.050 or 10.120.

    QUESTION: How much is F2.19?

  • Joel N3GSE:

    I am sure you know and checked this. I had the same problem and it turned out simply my power out was way too high.
    Originally, I was at 35 watts (PSK31) and went down to 10-15 watts. This is the lowest my rig will go. JT9-1 is an amazing mode!

  • WD6GRI:

    no i get its f-n frustrating but YOU must ck that youre xmiting as all told its in the ant if you have power a good match SWR you are herd as transmitting 300mw-300watts wont cut the ice but a good ant will be 5-9 all over at any out put !!!! puter works fine as most likley the rest of ur setup the ant needs too be foucused on its whacked might loook good but isnt matched ? grounded as well as all the rest of youre eq. not throubh the wall socket NO . sep too just 12 ga. solid too a ground spike brass or correr is best abt 3ft deep and in old days id soak this area w/ salt water ??? it worked 4 me n still does — just dont throw money on a puter for the same results ?? i say give it a break for a day ?? cul …. ..
