⚠️ 5 Fatal Traps in Morse Code, Telegraphy & Audio Demodulation
💥 1. ITU-R M.1677 Standard Timing Ratio Violations
International Morse adheres to strict ITU-R timing math: 1 dot = 1 unit, 1 dash = 3 units, intra-character space = 1 unit, inter-character space = 3 units, and inter-word space = 7 units. Naive software keyers that use arbitrary delay loops or fail the standard 1:3:7 formula create choppy, uncopyable CW on amateur radio bands.
⚖️ 2. International (ITU) vs. American Railroad Morse Confusion
Original American Morse (used on 19th-century landline telegraphs) differs radically from Continental/International ITU Morse. For example, in American Morse, the letter "C" is .. . (two dots, space, dot) and "O" is . .. Sending American Morse over maritime radio or modern aviation beacons causes catastrophic signal misinterpretation.
🛡️ 3. Prosign Fusion Errors & Procedural Signal Splitting
Procedural signals (prosigns) such as SOS (...---...), AR (end of message, .-.-.), and SK (end of contact, ...-.-) are keyed as single continuous compound characters without the standard 3-unit inter-character gap. Splitting them into separate words (e.g. S O S) is technically invalid in emergency maritime distress protocols.
🔍 4. Modern Browser Web Audio API Autoplay Restrictions
Chrome, Safari, and Firefox strictly enforce autoplay security policies that keep the browser AudioContext in a "suspended" state until a direct, user-initiated click or tap occurs. Any script attempting to synthesize Morse sidetones without first calling audioCtx.resume() fails silently with zero audio output.
🚀 5. Punctuation Collisions & Slash Delimiter Ambiguities
Informal text representations of Morse code frequently employ the forward slash (/) to demarcate word boundaries. However, the ITU character for a literal fraction slash is -..-.. Parsing raw Morse streams without explicit delimiter escaping scrambles radio callsigns and coordinate bearings.
