LEARN AND CHECK
Morse code guides and references
Choose a task rather than read everything at once. Start with a known message, use a reference to resolve a question, then check the result in the translator.
Start with the basics
Understand the code, then practice a message you can check.
- What is Morse code?
Characters, signals and the difference between a code and a language.
- Write Morse code
Accepted symbols, letter spaces and word separators.
- Timing and audio
Dot and dash lengths, silent gaps and WPM worked examples.
- Character practice
Recognize a written pattern or listen to an individual character.
Check a reference
Use these pages while encoding, decoding or checking a design.
- Alphabet and numbers
A–Z and 0–9 with International audio and American comparisons.
- Punctuation
All supported symbols with standard and extension labels.
- Numbers converter
Leading zeroes, dates, decimals and punctuation preserved.
- Printable sheet
A compact reference for paper or offline study.
- American Morse
Different mappings, internal spaces and long marks.
Read a complete message
See the letters, check the boundaries and listen to a worked pattern.
- Phrases and names
HELLO, HELP, I LOVE YOU and names with grouped examples.
- SOS
Compare the continuous signal with ordinary spaced letters.
- Read an image manually
Preview a photo and transcribe its marks; automatic scanning is unavailable.
- Audio decoding explained
Understand tone detection and timing; recorded-file conversion is unavailable.
Explore a particular use
Specialist references explain conventions and demonstrations, with sources for further study.
- Learning methods
Koch character selection and Farnsworth timing without performance guarantees.
- CW abbreviations
Distinguish abbreviations, Q-signals and continuous prosigns.
- Audio puzzle example
Build and test a short, readable clue.
- Keys and keyers
Compare the mechanisms that produce marks.
- Current uses
Explore contexts in which the code appears today.
