The true strength of the K3NG keyer is its modularity. You can expand your schematic to include:
For a professional, RF-shielded finish, you can find open-source K3NG PCB designs on repositories like GitHub or OSH Park. A custom PCB minimizes wiring errors and allows you to easily house the project in an aluminum enclosure. 5. RF Immunity: Crucial Design Considerations k3ng keyer schematic

Safely interface Arduino’s 5V logic to the transceiver’s key input (which may be 0–12V, high impedance, or require current sinking). or require current sinking).
