What is an electronic keyer?

An electronic keyer is specifically designed to assist operators in sending Morse code more efficiently. It does this by automatically generating Morse code tones based on the input from a paddle or a keyboard. This allows the operator to send messages at high speeds and reduces the physical effort needed compared to sending Morse code manually. The electronic keyer interprets the operator's taps on the paddle as dots and dashes, enabling smooth transmission of Morse code.

Keyers also often feature adjustable speed settings, allowing the operator to customize the sending speed according to their proficiency and comfort level. This functionality makes electronic keyers a valuable tool for amateur radio operators who frequently communicate using Morse code.
