Transmit question with WSJT-X

Golden23412

I am trying to get a 6400 up and running on Windows 2.4.9.  Ultimately, I'm trying to use my Macbook Air (DogparkSDR, xdax, xcat), but for now, I just want reliable operation on my Windows machine.

Last night, I was getting FT8 QSOs on WSJT-X.  I could see in SmartSDR when it was receiving and transmitting.  During WSJT-X transmit, I could see RF power in SmartSDR was approaching 100 watts, and SWR is close to 1.4.  

Now, when WSJT says it's in Transmit mode, I don't see any RF power or any flicker on the SWR meter.

In Dax, TX Stream is on.
In SmartSDR, DAX is set as primary transmit audio source.

When I click the Tune button in SmartSDR, it does show expected tuning RF power.

In WSJT-X, Test PTT appears to work as expected, by turning on MOX, but no RF power is shown.

I can't seem to figure out what's wrong.  Can anyone point me in a good direction?

DAX turned on?

So ptt is fine but essentially there is no tx audio when using WSJT. In the WSJT set up (from memory i think it is the Audio tab) have you correctly selected the TX Audio...I. e. The tx dax channel ?

Ok, weird.  Everything seems normal again.  I don't know if it was something I clicked or not.  The last thing I changed before it started working again was re-selecting Dax 1 in the SmartSDR waveform window for slice A (not in the TX settings).

Try this, may work or may not, I don't run ft8, I assume you have a mic profile setup for Ft8? On my 6400 , ver. 3, sometimes when I key to talk there is no transmit, radio keys but nothing out. So I click different mic profile and just talk into Mic and it worked, switched back to regular mic profile and all was good, done me that way once today. Just an idea!
