: Support for USB/PS2 keyboards, rotary encoders, and paddle sets. k3ng keyer schematic

Keep the analog potentiometer and paddle lines as short as possible to minimize RF pickup.

: For those using an Arduino Mega, the UN7FGO K3NG Shield is a highly recommended PCB design that breaks out all major features. Configuration & Setup keyer_pin_settings

The K3NG keyer offers several benefits to amateur radio operators:

House your keyer in a metal/aluminum box. Ensure the box is connected to the circuit's ground plane. How to build the contest memory system

For contest logging or keyboard keying, you can wire a legacy PS/2 keyboard port directly to the Arduino: PS/2 Data Pin connects to Arduino Digital Pin D3 . PS/2 Clock Pin connects to Arduino Digital Pin D8 . Connect the keyboard’s power lines to and GND . 4. Constructing the Circuit: Breadboard to PCB

: Non-volatile storage for standard contest exchanges and CQ calls.
