Morse Code


This program teaches you to receive Morse code. It starts with a few letters and adds more when it sees that you are ready. The program won't teach you to send code except that sending is easy to learn on your own once you know how the letters sound.

Getting Started

In the top-left, choose the order in which you'd like to learn, and whether you wish to learn numbers, symbols, or only letters.

It probably doesn't make much difference which you pick, but I'd reccommend you pick one and stick to it.

In the top-right, set the Speed fast enough that letters sound like a single sound, not a sequence of dots and dashes. Adjust the Tone to a pitch that you find pleasing.

Click in the text field to start the program sending. It will send one letter and then wait for you to type it. It ignores wrong answers and does not penalize you for guessing. If you don't type the right letter the program will eventually show you the letter and send it again. Let it do this a few times to learn a new letter. Press the ESC key to pause, and click in the box again to resume.

The program shows blue bars for the letters it has chosen for your practice. Letters it is saving show in gray. The length of the blue bars indicate how much emphasis the program gives each letter. You can also click on the bars to enable/disable letters yourself if you feel you need more control, but you wouldn't normally need to do this.

Learn Quickly

You will enjoy learning the code more if you do it quickly. You will need determination that lasts for a week or two. These tips will help you learn faster.
