Wireless CW Decoder Learning Kit

This CW Morse code decoder kit supports wireless telegraphy education through direct audio signal input and character-level decoding. Its compact design uses plastic construction and integrates a US-standard power plug for AC110V input, converting to stable 9V DC internal operation at just 33mA — energy-efficient for extended lab or home use. Core functions include: real-time display of incoming Morse elements (dots, dashes, gaps); automatic translation into ASCII characters and digits; live bit rate readout; and an external push-button for generating practice signals. All features are implemented on a single printed circuit board, reflecting simplified yet functional radio communication architecture. Originally developed for early 20th-century wireless operators, Morse code remains a benchmark for signal integrity training — this kit preserves that legacy while delivering measurable, observable outputs that support structured assessment and progressive learning milestones.
