I have a Flex 6400. I am running Smart SDR 2.3.9. I installed FL-Digi and had it working. Made contacts on PSK-31. Did a new install of WSJT-X with intent to run FT-8. Now FT-8 will copy but not transmit and FL-Digi running PSK-31 will not copy. Is there some relationship to these two programs that might cause this or do I have something improperly set up?
