Working with WSJT-X

AA1SL

Hello,

I was able to setup Flex 6400 with Win11 WSJT-X and it worked fine until I used iPad with SDR app.

Now when I fire up WSJT-X on Win11 PC, I can see the traffic but no transmission.

Any suggestions how to fix it? I restarted both, radio and PC and it wont TX on Win11 software. Meanwhile iPad SDR works like a charm.

Thanks!

Is DAX set correctly and turned on?

Yeap, to 1 on radio and DAX app.
same CAT

Nothing was changed since first and successful setup.

Same setting. Everything works fine except transmissions.

Double check in WSJT-X settings radio tab that CAT is still selected for PTT and audio tab has DAX AUDIO TX selected for output. Go back to radio tab and test CAT and test PTT. If those both test good the only thing left to adjust is your DAX TX level.

I found the reason - I had Slice Master installed and from now on I’m expected to fire up first that app and after that SDR on Flex 6400 worked like a charm
