This circuit often uses a switching transistor, such as the 2N2222 , or an optocoupler to isolate the keyer from the radio’s circuitry.
An optional 10k or 100k pot allows for manual CW speed adjustment, typically ranging from 1 to 999 WPM. Advanced Hardware Options
The represents one of the most flexible and feature-rich open-source CW (Morse Code) keyer designs available to the amateur radio community . Developed by Anthony Good (K3NG), this Arduino-based project rivals high-end commercial keyers by offering extensive customization through a modular code structure. Core Schematic Components
One of the key reasons to study the K3NG schematic is its support for a wide array of peripherals: k3ng/k3ng_cw_keyer: K3NG Arduino CW Keyer - GitHub
Two digital pins (typically D2 and D5) are mapped to the left and right paddles to detect "dit" and "dah" inputs.
