My FTdx10 was working fine with DX4WIN using the enhanced CAT port from the Yaesu site. It has stopped working, and can't figure out why. I'm using the ON4AOI driver. Rig works fine with WSJT-X and N1MM+ using the enhanced com port (only one program running at a time). DX4WIN works fine with my K3 with a microHam interface.Any clues? Thanks, Frank W2YK
