About morse-code.org

morse-code.org is a specialized open-access educational initiative and browser acoustics project dedicated to preserving, modernizing, and teaching Morse code through standards-compliant tools and authoritative technical references.

Last updated: October 6, 2026

Our Mission and Purpose

Founded in 2026, morse-code.org was established to provide students, amateur radio operators, telecommunication historians, and educators with free, instant, and technically accurate Morse code utilities. While Morse code was retired from international maritime distress monitoring under the Global Maritime Distress and Safety System (GMDSS) in 1999, continuous-wave (CW) telegraphy remains a foundational pillar of amateur radio, emergency preparedness, assistive communication, and digital acoustics.

Our mission is to maintain an open-web reference and utility suite that operates without account barriers, subscription paywalls, or unnecessary cloud tracking, making telegraphy education accessible to anyone with a standard web browser.

Editorial Team and Technical Expertise

The tools and educational content on morse-code.org are created and maintained by a team of software engineers, digital signal processing (DSP) practitioners, and licensed amateur radio operators (CW enthusiasts) passionate about radio history and acoustics.

  • Radio & Telegraphy Review: Content covering prosigns, operating procedures, and signal history is guided by active amateur radio operators familiar with International Amateur Radio Union (IARU) band plans, ARRL telegraphy conventions, and real-world CW keying techniques.
  • Web Audio & Signal Processing: Our audio synthesis engines and microphone decoders are built by web engineers experienced with the Web Audio API, Web Workers, Canvas pixel manipulation, and browser-side frequency analysis (Goertzel tone detection and Fast Fourier Transforms).
  • Linguistic & Alphabet Curation: Our multilingual tables (covering Latin, accented Spanish, German Umlauts, French accents, Russian Cyrillic, and Arabic Morse) are reviewed against national standards and telecommunications conventions to prevent erroneous mappings.

Compliance with International Standards (ITU-R M.1677-1)

Accuracy is the primary design requirement for every translator, audio generator, and reference table on this site. Our implementation follows the formal specifications defined in Recommendation ITU-R M.1677-1 (International Morse Code), published by the International Telecommunication Union (ITU) Radiocommunication Sector:

  • Basic Unit Ratio: The duration of one dot (dit) is defined as one unit of time.
  • Dash Duration: The duration of one dash (dah) is equal to three units of time (3 dits).
  • Intra-Character Space: The interval between consecutive elements (dots and dashes) within a single letter is equal to one unit of time (1 dit).
  • Inter-Character Space: The interval between distinct letters within a word is equal to three units of time (3 dits).
  • Inter-Word Space: The interval between consecutive words is equal to seven units of time (7 dits).

For auditory practice, our sound generators default to pure sine-wave CW sidetones between 550 Hz and 750 Hz—the frequency band historically preferred by telegraph operators to reduce auditory fatigue during prolonged listening.

Privacy by Product Architecture: Local Client-Side Processing

Unlike modern generative AI services that route user inputs to centralized cloud servers for parsing, morse-code.org is architected with strict client-side privacy by design:

  • Audio Decoding: Uploaded audio files and live microphone streams are processed entirely on your device via the Web Audio API and local DSP algorithms. Your voice and ambient recordings are never transmitted to our servers or third-party transcription endpoints.
  • Image Recognition:The Morse Code Image Translator inspects graphical dots and dashes using HTML5 Canvas pixel scanning in your browser's memory. Your images remain private and are discarded when the tab closes.
  • Text Translation: Translation between human text and Morse code occurs instantly in local JavaScript memory without cloud logging.

Fact-Checking and Editorial Methodology

All historical narratives—including our detailed accounts of the 1906 Berlin International Radiotelegraphic Convention, the adoption of SOS over CQD, and the 1912 Titanic distress dispatches—are synthesized from verified archival records, ITU treaty publications, and established maritime history documentation.

We do not publish machine-spun or unverified summaries. When revisions or historical clarifications arise, updates are reviewed against source documentation and logged with a clear revision date.

Educational and Safety Boundaries

morse-code.org is strictly an educational, historical, and utility publication. It is not an emergency communication service, an official rescue dispatch system, or a licensing authority. While our guides explain recognized maritime distress signals such as SOS, users in urgent life-safety situations must always contact official local emergency services and use certified radio channels.

Sustainability and Advertising Policy

To maintain all tools as a free public resource without paywalls or mandatory accounts, morse-code.org displays non-intrusive digital advertisements through Google AdSense.

We adhere strictly to Google Publisher Policies: advertisements are never disguised as navigation, do not trigger forced redirects or deceptive popups, and are strictly prohibited on interactive game screens or thin utility views. Advertising revenue directly covers our hosting, domain management, CDN bandwidth, and ongoing tool development.

Contact, Errata & Institutional Transparency

We welcome peer feedback, technical corrections, accessibility audits, and inquiries from amateur radio clubs, schools, and museum curators. If you identify a bug in our audio engine, an irregular Morse code mapping, or an accessibility barrier:
