Working with WSJT-X

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

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
