T4A12 - What is an electronic keyer?

Question

What is an electronic keyer?

Answer Options

  • A) A device for switching antennas from transmit to receive
  • B) A device for voice activated switching from receive to transmit
  • C) A device that assists in manual sending of Morse code
  • D) An interlock to prevent unauthorized use of a radio

Correct Answer: C


Explanation

An electronic keyer is a device specifically designed for operating Morse code (CW). It is a device that assists in manual sending of Morse code by electronically generating perfectly timed dots and dashes.

The operator uses a dual-lever paddle (often called an ‘iambic paddle’) that sends dots when one side is pressed and dashes when the other side is pressed. The keyer then automatically outputs the correctly timed sequence to the radio’s CW keying input, allowing for rapid, perfectly formed code.
