Marks drawn to their real length

Each dit (the short signal) is a dot, and each dah (the long one) is a bar three dits long, with a gap of one dit between the marks of a letter. That is the timing ITU-R M.1677-1 sets, so the sheet shows the rhythm students will hear.

A is a dit and a dah, the shape in the Morse Universe logo.
