Morse Beacon Team
Morse Beacon is built and maintained by a small team of web developers and amateur-radio hobbyists who wanted Morse code tools that work on a phone, in a browser, with nothing uploaded. Every translation table is built on ITU-R M.1677-1, plus common non-ITU punctuation such as !, and checked by automated round-trip tests on every release; prosigns and abbreviations are cited to ITU-R M.1172 and ARRL operating guides. The microphone and camera decoders are tested against real recordings from phones, not only synthetic signals. If anything looks wrong, report it to morsebeacon@gmail.com.
How we check our pages
Patterns. The tools and charts use one International Morse table, checked against ITU-R M.1677-1. Every supported character has an encode/decode test.
Timing. A dot takes one unit, a dash three. Gaps are one unit within a letter, three between letters and seven between words. PARIS plus its following word gap is 50 units.
Meanings. We distinguish individual letters from joined procedural signals, using ITU-R M.1172 and ARRL operating references. Meanings depend on context.
History. We include claims only when there is a checkable source. Practice memory cues are original learning aids, not official Morse terminology.
