About MorseCoder

Independent Morse tools · ITU-R M.1677-1 · No fabricated operator identity

These pages document a free browser translator and trainer. Timing follows International Morse (ITU-R M.1677-1). We do not claim an FCC callsign or Extra Class license for the site operator. Use the tools for practice; licensed instruction still matters for on-air work.
