7 in Morse Code

In International Morse code the number 7 is --...: 3 dits and 2 dahs, 13 units long (about 780 ms at 20 WPM).

It sounds like "dah-dah-di-di-dit".

In MORSE HQ's Koch training, 7 is character 32 of 41.

• 2..---opposite signals
• 3...--reversed
• Z--..one signal shorter

Learn it by sound instead of counting dots and dashes. Say "dah-dah-di-di-dit" out loud, then listen to it at full speed.

Like the Koch method, hearing characters at your target speed (15-20 WPM) from day one makes it easier to speed up later.
