[Elecraft] K3 USB audio CODEC TX audio issue

[jeff griffin]

Jeff,
Just checking things I have forgotten in the past.
You do have the mode set to Data and the Data sub-mode set to Data A
correct?

Yup.

Make sure the new version of WSJT-X still has the correct codec selected.
Also, Open the Windows volume control and check the 
volume level for the codec 

Went over all settings, still no TX. I even swapped out the USB cable. I
connected a IC-9100 I brought up here with me to use as a SAT radio backup
and after 5 minutes I had contacts on FT8. I think there is something wrong
with the KIO3B, looks like I will be calling Elecraft on Monday...
