PTT help KX3/KXPA100

[Michael Dinkelman]

Trying to get PTT working with a boom mic into the KX3.
The microphone works fine using VOX into the microphone jack of the KX3.
Of course, XMIT works too.

Trying to trigger PTT using the GPIO port of the KX3/KXPA100 accessory
cable.
1) MICBTN configured to OFF  (tried PTT too)
2) ACC2 IO configured to LO=PTT

No PTT when using a mono plug into the GPIO port
Gotta be something simple. What am I missing?

(I would try at the ACC2 port on the KX3 itself but no 2.5mm TRRS plugs
at this point)

cheers
mike, n7wa

The ACC2 port is 2.5mm TRS, not TRRS.
