Questions tagged [morse-code]

For questions that are about Morse code by itself that aren't directly radio-related, including questions about learning to send or receive Morse code. Questions about Morse code modulation modes (OOK, MCW) should use the "cw" tag instead. This is the right tag for questions about Morse code in a movie or a song, or about learning to send or receive Morse code, or about the use of Morse code for computer input devices.
