Question
What does it mean when a CW operator sends “KN” at the end of a transmission?
Answer Options
- A) No US stations should call
- B) Operating full break-in
- C) Listening only for a specific station or stations
- D) Closing station now
Correct Answer: C
Explanation
The prosign ‘KN’ (typically sent as the letter ‘K’ followed by the letter ‘N’, run together) is a procedural signal used at the end of a Continuous Wave (CW) transmission. It signifies that the transmitting operator is listening only for a specific station (or stations) to respond, and requests that other operators remain quiet.
This is often used in a sequence like ‘W1AW KN’, meaning W1AW is only listening for the station it was just talking to and no one else should break in. This allows the two stations to maintain control of the frequency and avoid unnecessary interference from other callers.
