Ü in Morse code

Ü, U with an umlaut, is dot dot dash dash in Morse code, said “di-di-dah-dah”. It is a national extension used in German, Hungarian and Turkish, not part of the ITU standard. It lasts 11 units, which is 660 ms at 20 WPM.

Will the other station understand it?

Only if they expect it. Ü is not in the ITU standard; it is a national extension, understood mainly between operators who share one of these languages.

Other national tables give the same code, ..--, to Ŭ. The letter it means depends on the language of the message.

When you are not sure, send UE instead. Every operator can copy that.

The code is U with one more dash, the same way Ö is O with one more dot.
