Welcome to the k3ng_cw_keyer wiki!

Look to the right for documentation and help topics ---->

(Like most things in the open source world, this wiki is under construction / evolving. If you would like to volunteer to help make it better, your assistance would greatly appreciated and your name and callsign would be immortalized as a supporter of this project.)

The K3NG Keyer is an open source Arduino based CW (Morse Code) keyer with a lot of features and flexibility, rivaling commercial keyers which often cost significantly more. The code can be used with a full blown Arduino board or an AVR microcontroller chip can be programmed and used directly in a circuit. This keyer is suitable as a standalone keyer or for use permanently installed inside a rig, especially homebrew QRP rigs. It’s open source code so you can fully customize it to fit your needs and also perhaps learn from it or find coding ideas for other projects.

A circuit board and parts kits called the nanoKeyer is available from DJ0MY, and Hamshop offers a kit called Open CW Keyer which uses this software. RemoteQTH also offers the Open Interface which runs this code.



The K3NG Keyer has been feature in the following videos.


Check the following pages for information on constructing your own keyer.

Also check out KF4BZT's article for lots of hints on working with the schematic for beginners and working with the components including lots of pictures.

Jmatonis has published on Thingiverse a 3D model of his keyer enclosure.

Cees, PA3CVI, has published an excellent Dutch manual and an English Translation.
