Software Tools for Decoding Morse Code Signals
Find and download software applications that convert Morse code audio into readable text for amateur radio use.
Morse code, or CW, remains a fundamental mode in ham radio, valued for its efficiency and readability even under weak signal conditions. Many operators enjoy CW for casual QSOs, contesting, and chasing DX on the HF bands. While skilled operators copy CW by ear, software decoders provide a valuable tool, especially for beginners learning the code or when signals are very weak.
This category features various software tools designed to decode Morse code signals received by your station. Hams can find Windows programs like CW_Shark and CwGet, which use a computer's sound card to translate CW audio into text. There are also specialized decoders for Linux, such as RSCW, optimized for digging weak signals out of the noise. Mobile operators can even find applications like HotPaw MorseDecoder for iPhone and iPad, turning a portable device into a CW decoding station.
