1 in Morse Code

1·−−−−

1 in International Morse code is ·−−−−: 1 short and 4 long. Every number in Morse code is five signals long. In cut numbers, the short form operators use when numbers are expected, runs of dashes are cut to one.

What ·−−−− means in every alphabet

The same signal stands for different letters in different national codes. This is everything it means in the alphabets this site supports.

International Morse (ITU)

Easy to confuse with: 6 (−····, dots and dashes swapped), 9 (−−−−·, the same signals in reverse).

1 in cut numbers

When both sides know numbers are expected, operators shorten 1 to ·−, the same signal as the letter A. Only the runs of dashes are cut; the dots stay.

1 in American Morse code

In American (railroad) Morse code, 1 is sent as ·−−·, not ·−−−− as in International Morse.
