K3ng Keyer Schematic

Silas picked up his coffee. "The K3NG schematic isn't just about making noise, Elias. It’s about offloading the tedious work to the machine so the operator can focus on the art. It’s a bridge between the heritage of Morse code and the modern world."

Most radios (Icom, Yaesu, Kenwood) have a "key line" that sits at +5V, +8V, or even +12V. The Arduino can only handle 40mA and 5V. Hooking it directly will release the "magic smoke." k3ng keyer schematic
