How the timing works

Speed is measured in words per minute. The ▶ buttons here play at about 15 words per minute.

Questions

What is SOS in Morse code?

Three dots, three dashes, three dots: · · · − − − · · ·. It is sent as one unbroken signal with no gaps between the letters. It does not stand for anything; it was chosen because it is easy to send and hard to mistake.

How long is a dot and a dash?

A dash is three times as long as a dot. The gap inside a letter is one dot long, the gap between letters is three dots, and the gap between words is seven.

What is the most common Morse code letter?

E, which is a single dot. T is a single dash. The commonest letters in English were given the shortest codes, which is why Q and Y are long.

How do I translate text into Morse code?

Open Phonetic Relay in Morse mode, type your text and press play to hear it beeped out at the speed you choose.

Is Morse code still used?

Yes, by radio amateurs, in aviation beacons that identify themselves in Morse, and as a last-resort signal with a torch or a whistle.
