DAX will not show any TX options for WSJTX

DonD Member
Win 11, SmartSDR/Dax/Cat 3.6.8
CAT works. PTT Works. Setting up WSJTX. Decode works fine. RX is set to DAX RESERVED AUDIO RX 1. In the drop down menu to choose TX there is no TX option. DAX TX STEAMING IS BLUE. MIC STREAM IS BLUE, RX STREAM US BLUE. Flex keys for emit but no audio. How do I enable the TX function to show in the dropdown. Thanks

    You don't have an option for "DAX Audio TX" in the dropdown in WSJT-X? There's only one, it's not numbered like the RX DAX devices.

    Do not use any "DAX RESERVED AUDIO" port. It says "reserved" for a reason - it is only to be used by SmartSDR for internal functions. Instead, use the DAX Audio RX 1 (or 2, 3, etc.) as shown by KM8V for interfacing to other software.

    Thank you both for the answers. The issue is I do not see any choice for "TX". The screen shot shows my dropdown (in two parts) from the WSJTX menu (Settings>Audio). I have uninstalled and reinstalled both SmartSDR 3.6.8 as well as WSJTX 2.6.1. I have successfully run the Flex/WSJTX/SmartSDR in the past on this radio, but the radio has been factory reset since that time so I am starting from scratch again. This is also Win11 now running on a new laptop. Please see the screen shots. Thanks Don

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.
