[Elecraft] KX3 Headphone set up problem

[Walter Underwood]

The mic plug is shorting the “mic button” (PTT) contact. Set MIC BTN to OFF in the menus or use an off the shelf stereo to mono splitter.

I described the latter in this blog post. The splitter also gives you cleaner mic bias and a PTT jack.
