K3ng Keyer Schematic ~upd~ Jun 2026
"It supports LCDs, PS2 keyboards, potentiometers for speed control... hell, it even speaks in Morse if you want it to," Silas explained. "But the core schematic is simple. You have inputs for your paddles, outputs for your rig, and a few resistors to keep things polite."
Modern K3NG schematics use . This requires only 4 wires: k3ng keyer schematic

"Rube Goldberg would be proud," Silas grunted. "But if you want elegance, you don't need a bucket of logic chips. You need the K3NG." You have inputs for your paddles, outputs for
Similar to keying, PTT requires a transistor switch. Many K3NG schematics dedicate a separate pin (e.g., D13) for PTT. This allows the keyer to put the radio into transmit mode before the first dit—essential for QSK (full break-in) or semi-break-in operation.
