E in Morse Code

E is . - dit, 1 units, 60 milliseconds at 20 words per minute.

How long E takes

E is 1 dot and 0 dashes. With the gaps that comes to 1 units, number 1 of 26 by length.

  • 5 WPM: 240 ms
  • 13 WPM: 92 ms
  • 20 WPM: 60 ms

The arithmetic behind them is on the timing page.

What E gets confused with

3 characters sit one element away from E:

  • A .- - one more dash on the end
  • I .. - one more dot on the end
  • T - - a dash in first place instead of a dot

E in the tree

  • Carries on into: A, F, H, I, J, L, P, R, S, U, V and W (12 of the 26)
  • Backwards: . = itself, a palindrome
  • Koch position: 15 of 26

The tree shows the whole shape, the trainer teaches it by ear.

Why E has this code

E makes up about 12.7 per cent of English text, which is number 1 of 26 by frequency, against number 1 by length. The two ranks are identical - as good a fit as the code manages for any letter.

The lengths were set by counting, not by theory - the alphabet page has that story.

Worth knowing about E

A single dot is also what a stray click sounds like. Garbled copy sprouts Es for that reason, and an operator who sees a line of them suspects the receiver before the sender.
