LCD Morse Code Decoder CW Reader

This compact CW decoder features a 1602 LCD display for clear, real-time Morse code translation. It supports dual power input: DC 5–12V at 500mA or a built-in 3.7V lithium battery with USB-C charging — ideal for field use and portable ham radio practice. Constructed from durable PC + metal housing, it includes two onboard LEDs indicating full charge status. The unit accepts direct input from a Morse key via the CW key socket, and offers adjustable signal sensitivity (via 103 potentiometer) and LCD contrast (via 102 potentiometer). A red button toggles space character recognition on/off during decoding, giving users precise control over output formatting.
