Morse Code Chart: American, Continental & International (ITU) Standards #3365808 (License: Personal Use)

This chart displays the standardized dot-dash representations for the Latin alphabet (A-Z), numerals (0-9), and common punctuation/symbols across three Morse code systems: American (Morse), Continental (Gerke), and International (ITU). Differences are highlighted-such as Gerke’s use of shorter dashes or ITU’s adoption of unified spacing-reflecting evolving telegraphy practices from the 19th to 20th centuries. The visual layout enables quick cross-referencing for learners and professionals alike.

This image is commonly used in educational resources, amateur radio training materials, telecommunications history articles, and technical documentation where understanding legacy and modern Morse encoding is required. It serves users seeking to decode historical messages, compare standards, or prepare for licensing exams (e.g., FCC or IARU).
