Top CW Words
This trainer is a small personal project designed to play
with learning morse code through the Farnsworth method.

character currently being sent. It is my hope that this will
help form a stronger link between the
sound of CW
and the meaning of the sound.

There are three possible options for display mode.

Delayed: The character will be displayed
starting immediately after the character has
been sent. Type
