TX in digital mode

Terry L Angle

I have a new 6400M I have read about setting up for digital modes. I have downloaded Smart software and placed Slice A & B in a place I can find it. I have set up DAX, CAT, and SDR. Next, I downloaded Fldigi and set up the config. The problem I am having is the 6400m is receiving but will not TX. The TX ready is not green and if I do TX the radio acts like it is TXing but no power going out. I have to change the playback to all the different options given to me and still no TX. Need help

    Hi Terry
    If your digital program is set up correctly then on the left hand side of SmartSDR screen about half way down in the panel that you set the MIC levels in there is a Button called DAX, click this ON to get your FLDIGI to stream audio out of your transmitter. 

    IF YOUR RUNNING with the PC MIC then to transmit voice again you will need to turn this button back off they will NOT work at the same time UNFORTUNATELY.

    Brat, thanks for your reply. I attached some snip from my computer running SDR v3.1.8. You can see the Dax is mic streaming. You can see the red line for receiving. In the Fldigi I have the Dax Audio TX in the playback On the radio screen I have DAX on channel 1.                       

    I also want to know when I have SDR running and a Monitor in HDMI on the radio, which one am I listing too.

    Note that if you use Slice Master to launch fldigi (or any of the other supported digimode program), Slice Master will manage the DAX button for you.  So it will at least appear as if you can do both at the same time.
