At its most basic, the K3NG keyer requires an Arduino (Uno, Nano, or Mega) and a few interface components: Processor: Typically an Arduino Nano for basic builds, or an Arduino Mega for feature-heavy versions requiring more pins and memory. Paddle Input:
Keying output (transmit key) Option A — Transistor (recommended simple): k3ng keyer schematic
He tapped the right paddle. A smooth dah . At its most basic, the K3NG keyer requires
A "bare bones" schematic uses just two paddles. A "full" K3NG schematic looks like a cockpit. A "bare bones" schematic uses just two paddles
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.
