Thanks Wayne - you are correct - that XMIT button does it, although my installation makes it cumbersome to use that method. I will look into the ACC2 option in the morning. I do see that my KX3 has a “splitter” plugged into the ACC2 jack and I labelled it “PTT: KPA500”. I have my station set up so I can run the KPA500 behind the KX3 is desired. So I’m figuring I got that connector cable from Elecraft for this purpose. It has a single male TRS plug and two jacks: one RCA and the other is teensy, looks like 2.5mm. More investigation needed here….(I can hardly remember what I had for dinner, tonight let alone what that cable was gotten for!)
