Flwkey is a lightweight Windows utility published by W1HKJ that provides a streamlined graphical interface for controlling Winkeyer-compatible Morse code keyers used in amateur radio operations. Classified under the Communication / Ham Radio category, the program translates typed text or pre-loaded messages into precisely timed CW (Continuous Wave) signals, enabling operators to conduct high-speed, error-free Morse transmissions without manually manipulating a paddle. Typical use cases include contest logging, DXpedition pile-up management, automated beacon operation, and everyday QSOs where consistent spacing and variable speed control offer a competitive advantage. By exposing only the essential Winkeyer commands—speed adjustment, message buffers, PTT line, and sidetone volume—Flwkey keeps the workspace uncluttered, making it suitable for both field-day laptops and permanently shack-mounted PCs. Version 1.2.3, the sole release to date, implements the complete Winkey 1/2 protocol set, supports USB-to-serial adapters with non-standard COM numbers, and remembers window placement and last-used baud rate between sessions. Because the executable is self-contained and requires no installation, it can be launched from a thumb drive on any Windows version from XP onward, ensuring portability for portable or emergency operations. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
