@irad d Unfortunately, no change with either Rig 1 or Rig 2. Wonder what is up with my particular configuration. I suppose I can just pay attention and manually switch TX back before I try to transmit after switching frequencies. Sorry, Charles

@irad d thanks for your continued efforts. I've attached the OmniRig configuration that works with my HF rig as I have it configured. 73, Charles W1ZPB

Hmm. It's possible that I've set things up incorrectly, but I'm not seeing anything obvious in Omnirig or my radio's manual that might cause split in digital operation. I tried using another rig profile to control it (FT991-DATA) and it does the same thing. JS8Call is using only VFO-A with Omnirig rig 1 when changing frequencies. flrig/fldigi seem to force VFOA, but obviously they are working differently. Interesting and possibly related - some times when I change frequencies (especially 14.105) VacAC shows three "Omnirig: Change frequency" entries within a second of each other. Looks like this in the log: 27/11/2021 12:26:49 - OmniRig: Change frequency - manual freq change with one entry 27/11/2021 12:27:05 - OmniRig: Change frequency - manual freq change with one entry 27/11/2021 12:27:22 - OmniRig: Change frequency - manual freq change with one entry 27/11/2021 12:27:44 - OmniRig: Change frequency - manual freq change with three entries 27/11/2021 12:27:44 - OmniRig: Change frequency 27/11/2021 12:27:45 - OmniRig: Change frequency And even when I see only a single "Change Frequency," the TX light for VFO-A lights up for a fraction of a second, then turns off and the TX for VFO-B lights up. Any debug logging I can turn on to give us an idea what sort of messages are going back and forth via Omnirig?
