Good Afternoon All,
I am having this same problem but only from 18mhz on up. On 14mhz down, the rig (IC7100) interfaces normally and well with WSJT-x and FLRIG. Icom radios do have a one USB cable, as we all know, for CAT and AUDIO. Is my issue attributable to the same reasons as the failure others are experiencing? I have tried changing antennas, taking the tuner out of the mix, changing USB cables but the problem persists. Any help would be most appreciated.
