Device Overview

The PDA provides a means to connect a standard CW key to the front of the Elecraft KX3.  The CW key shipped with the KX3, the KX3PD, connects to a 2x2 0.1” pitch header with thumbscrews.  The PDA replaces the KX3PD offering a standard stereo jack for connecting your CW key.

The PDA is offered as a kit.  It requires a bit of soldering to attach the header and stereo jack.

The stereo connector for the CW key can be installed in one of two orientations based on the type of connector you have on your key.  The receptacle can be either parallel or perpendicular to the front of the KX3.

The kit ships in a pink anti-static bag which contains the following.

Assembly

For assembly, you will need a soldering iron, solder, and a philips head screwdriver.

  1. Solder the right-angle header to the PCB.

NOTE: The right angle header must be soldered elevated off the board to allow the right-angle brackets holes to line up with the holes on the KX3.  

Please refer to the following photos.  

It is recommended to solder a single pin and then heat the solder to align the header so it is as high off the board as possible.
