Reference dictionaries for codes and alphabets used in radio, aviation, maritime signaling, electronics and transport: NATO phonetic alphabet, Q-codes, ten-codes, maritime signal flags, semaphore, resistor color codes, hazmat placards and braille.
8 of 8 tools
This subcategory gathers reference dictionaries for the most commonly searched codes and alphabets: the phonetic alphabet used in radio and aviation, ham radio Q-codes, police and CB ten-codes, maritime signal flags and semaphore, the resistor color code, hazmat placards and the braille alphabet. Each tool is a single table built to help you find the right meaning fast, including on mobile.
Where a code's meaning varies by region, agency or convention (like ten-codes), the tool shows that explicitly instead of presenting a single answer as if it were universal. Everything runs locally in the browser, with no signup.
NATO Phonetic Alphabet and Maritime Signal Flags and Semaphore (with a text speller), Q-Codes and Ten-Codes (with search and variant comparison), Resistor Color Code (chart and band calculator), Hazmat Placards and the Braille Alphabet (with real Unicode).
Yes, each one cites the official sources used (ITU, ICAO, IEC, DOT/PHMSA, BANA, among others) on the page itself. Where there is no single standard (like US ten-codes), the tool makes that explicit instead of forcing a single answer.
