Question
What is the function of an electronic keyer?
Answer Options
- A) Automatic transmit/receive switching
- B) Automatic generation of dots and dashes for CW operation
- C) To allow time for switching the antenna from the receiver to the transmitter
- D) Computer interface for PSK and RTTY operation
Correct Answer: B
Explanation
An electronic keyer is a device used by amateur operators to send Continuous Wave (CW) or Morse code. It works by interpreting the operator’s input (usually from an iambic paddle) and then electronically timing and generating the precisely spaced dots and dashes.
The keyer’s main function is the automatic generation of dots and dashes for CW operation. This ensures a perfect 3:1 dash-to-dot ratio and correct spacing, which makes the transmitted code signal clean, consistent, and much easier for the receiving operator to copy, especially at higher speeds.
