CW (Continuous Wave) Keying

Continuous Wave (CW) keying is a method of transmitting radio signals by turning a radio transmitter on and off to create Morse code messages. When the transmitter is on, it sends a steady signal; when off, no signal is sent. This on-off technique encodes letters and numbers in a way that can be received and interpreted by radio operators. CW keying is valued for its simplicity, efficiency, and ability to reach long distances with low power, making it a popular mode for amateur radio operators and in situations where reliable, energy-efficient communication is needed.
