Frequently Asked Questions
- What do the difficulty ratings mean?
- Easy codes have short, distinctive patterns (E = dit, T = dah). Medium codes are longer but follow recognizable patterns. Hard codes like Q (––.–) and punctuation marks have complex sequences that take more practice to memorize.
- Is Morse code still used today?
- Yes, in amateur (ham) radio, aviation emergency beacons, and some military communications. The International Morse Code standard has not changed since 1865. Learning it is also required for certain amateur radio license classes.
