Add a second 3.5mm stereo jack to your KX2/KX3 to use for a second key, like a straight Key, or to connect a keyer!
You can leave this on and add more protection to your KX2/KX3 by closing a hole which has Ground and VCC - and is not used unless you have a a key attached at this location. It is only 3/8" thick, and allows the KX2/KX3 to still fit in Elecraft padded bags.
Assembly is really easy, with one connector being thru hole, and the other SMD but with large pads.
The kit comes with:
Note that in the kit, the 2x2 is hidden in the PCB/Case for protection.
Be very careful with the header. Check for shortcuts as GND and VCC are present on the header. If you solder the connector with the PCB mounted on the KX2/KX3 (e.g for alignment), make sure that there is no battery/power applied to the rig. We are not responsible for any damage that may occur to your device as a result.
The connector works best with a slim stereo extension cable which have small stereo jacks.
