The is more than just a redrawn diagram. It is a bridge between the raw, brilliant potential of Anthony Good’s code and the practical reality of a soldering iron and a radio shack workbench. Whether you are a contest operator who needs 10 memory slots or a SOTA activator who needs a keyer that fits in your palm, a well-repacked schematic turns a chaotic pile of wires into a reliable, beautiful tool.
Testing and Validation
: Use an opto-coupler (like a 4N25) or a transistor to isolate the Arduino from the radio's keying line to prevent damage from high voltages. Potentiometer (Speed) k3ng keyer schematic repack
