From http://elecraft.365791.n2.nabble.com/KX3-using-CW-key-as-PTT-switch-for-voice-td7564382.html I do this with a standard switch and a 2.5mm jack and a CM500 headset. Works FB.
*You can use the tip contact of the ACC2 jack as a PTT input. Set MENU:ACC2 IO to "LO=PTT". You can plug your key directly into the ACC2 jack if it has a 2.5-mm stereo plug. If not, you'll need an adapter like the one supplied as part of our KX3 accessory cable kit. 73, Wayne N6KR * On Fri, Apr 24, 2020 at 9:59 PM Nr4c <[email protected]> wrote: > Before plugging in the mic from Menu set mic buttons to OFF.
