The cheat sheet

  • Morse encodes text as sequences of two signal lengths, dots and dashes, also called dits and dahs.
  • A dah lasts three times the duration of a dit, which helps keep the rhythm steady.
  • E is the most common letter in English, so it gets the shortest code, one dit.
  • Letters are separated by a space equal to three dits, while words use seven dits.
  • Words are separated by a space equal to seven dits, longer than the three dits between letters.
  • Morse can travel as sound, light, or electrical pulses, including a flashing flashlight.
  • SOS is a prosign meaning this is the start of a distress message, and others should stay silent.
  • SOS is sent as one prosign, keyed without gaps between the characters.
  • CQ is broadcast to mean seek you, an invitation to anyone who hears the signal.
  • QTH means transmitting location, so operators use it to share where they are.
  • Morse uses a narrow bandwidth, so it is easier to copy through noise than voice.
  • Navigation stations transmit identification letters in Morse so pilots can confirm the station works.

Pop quiz

Think of your answer first, then peek.

  1. What does Morse code use to stand for letters and numbers?
    • Short and long signals called dits and dahs
    • Spoken words in a fixed order
    • Colored flags only
    Show the answer

    Short and long signals called dits and dahs. Morse encodes text as sequences of two signal lengths, dots and dashes, also called dits and dahs.

  2. Why is Morse code useful in noisy radio conditions?
    • It needs a bigger antenna
    • It uses a narrow signal that cuts through noise
    • It is always louder than voice
    Show the answer

    It uses a narrow signal that cuts through noise. Morse uses a narrow bandwidth, so it is easier to copy through noise than voice.

  3. Why do people use text-message symbols and emoticons?
    • To make phones heavier
    • To replace all words
    • To add meaning and tone to short messages

    • Trail directions
    • Email addresses
    • Weather reports
    Show the answer

    Email addresses. The @ character was added to Morse in 2004 so email addresses could be sent by code.
