: Allows the keyer to interface directly with logging software like N1MM.
Place your repacked board in an aluminum enclosure. Morse keyers are notoriously sensitive to RFI (Radio Frequency Interference).
The standard schematic often uses a simple piezo. The repack includes a small audio amplifier stage (e.g., LM386 or a transistor driver) to drive a small 8-ohm speaker. This provides a cleaner sidetone that can be heard over ambient shack noise.
