U in Morse code

U is dot dot dash: ..-

U..-

Remembering U

It sounds like di-di-dah. Say it out loud as you listen, and learn the rhythm rather than counting dots and dashes.
U has 3 signals: 2 dots and 1 dash. It takes 7 units of time to send, where a dot is one unit.
U is roughly the 13th most common letter in English. Morse code gives the shortest codes to the commonest letters, which is why rarer letters like U are longer.
Swap every dot for a dash and every dash for a dot and you get G (--.). Learning opposite pairs together helps them stick.
Read it backwards and you get D (-..).
Add more signals to the end of U and you get F, so it helps to learn these letters after U.

Translate your own words with the Morse code translator, see every letter on the Morse code alphabet chart, or practise sending on the decoder.
