Good morning. I am having a problem getting my K3S to save in the config menu the setting for PTT-PTT. When I set it for RTS-DTR, hit menu it works fine. Then I turn the radio off and back on and the PTT-PTT setting is back to OFF-OFF. What am I doing wrong? How do I get the Config menu to save the PTT-PTT setting to RTS-DTR? Tnx Jeff W7JW
