About the marks
  Every dit and dah is drawn to the real 1:3 timing ratio defined in
  ITU-R M.1677-1. A dit is one unit wide, a dah is three, and the gap
  between them is one unit. Most charts online use a period and a
  hyphen, which gets the proportion wrong.

Printing
  Pick the file for your paper: Letter for the US and Canada, A4 almost
  everywhere else. Print at 100% ("actual size") so nothing is cropped.
