While there is no single "fixed" schematic due to the project's modularity, a basic build typically includes these key elements: K3NG Arduino-Based CW Keyer and Homebrew Paddles - kk9jef He tapped the right paddle
The is intimidating only if you look at it as a monolithic diagram. Break it down: It is just five small circuits working together. The Arduino reads switches (paddles), processes your Morse code via the legendary K3NG firmware, and closes a transistor to ground your radio's key jack. k3ng keyer schematic
The K3NG keyer schematic has several key features that make it a popular choice among amateur radio operators:
