About

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

The main difference between this trainer and others is that I am experimenting with visual reinforcement by displaying the 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.

This page should work in any modern desktop or mobile browser, including Edge, Safari, Chrome, Firefox, and Opera. But, please be aware that it does not work in Internet Explorer, because IE does not support the Web Audio API.

Display

There are three possible options for display mode.

  1. Immediate: The character is displayed during the transmission of the character only, but hidden as soon as the character has been transmitted.
  2. Lingering: The character is displayed during the transmission of the character, but will hang around until the next character is transmitted.
  3. Delayed: The character will be displayed starting immediately after the character has been sent.
