I have V 2.11 working here this morning. Is there a button on the interface that is the same as the PFA button on the front panel of the TS-890? I use that button to transmit at low power to tune antennas using an external tuner. It would be great if that button could be turned on/off from the PC.
From what I can see having quickly scanned the Kenwood manual, there is a command to set/view what function each PFx button runs, but nothing that allows you to trigger that command.
