K3ng Keyer Schematic Repack ((install)) < 360p >

Use a solid, uninterrupted ground plane on the bottom layer of your PCB.

When you download a repacked schematic, you aren't just getting wires and symbols. You are getting someone’s battle report :

Several projects tagged “K3NG” have repackaged the schematic into a polished, single-page SVG graphic, ideal for printing and framing above your workbench. k3ng keyer schematic repack

A momentary tactile switch to enter the command mode for changing settings via Morse code.

By organizing your build into these modular blocks, the K3NG keyer becomes an incredibly approachable DIY project, giving you custom-tailored CW hardware built precisely for your amateur radio operating style. Use a solid, uninterrupted ground plane on the

Connects to a 1k-ohm resistor in series, followed by a 0.1µF capacitor to GND (forming a basic low-pass filter).

The repack provides two schematics: one for a simple NPN driver, one for a reed relay. For a modern solid-state rig, build the 2N2222 circuit. The repack shows an LED in parallel with the transistor base for visual keying feedback. A momentary tactile switch to enter the command

While the K3NG code runs on most AVR-based Arduinos, the is the gold standard for "repacked" builds due to its small footprint and built-in USB interface. Pin Mapping (Standard): D2 & D5: Paddle Left/Right (Dit/Dah) D13: PTT (Push-to-Talk) Output D11/D12: Keying Output (Transceiver connection) A0: Speed Potentiometer 2. The Repacked Schematic: Essential Modules

: Contemporary repacks, such as the Joan Perez Lopez GitHub version , consolidate the schematic into a professional PCB with SMD components . These designs often add:
