He soldered two 10k resistors between the input pins and the power rail. He tapped the paddle. BEEP. A single dit echoed through the shack speakers. It was alive.
No major changes to the original k3ng hardware required – just 4 extra wires and a small firmware update. k3ng keyer schematic
The K3NG Keyer is not a single fixed schematic but a around an Arduino (Uno, Nano, Mega, Teensy, etc.). It supports: He soldered two 10k resistors between the input
: Most builds use an Arduino Uno for basic needs or an Arduino Mega 2560 for memory-intensive features like LCDs and full macro support. k3ng keyer schematic
