Morse Code Keyer Practice
Learn to send Morse, not just copy it. Key with a straight key or iambic paddles, using the keyboard, your mouse or finger, or a MIDI key, and see your sending decoded as you go. Meters show each press and pause, and the practice mode gives you words to send.

How your sending is read
With a straight key, how long you hold the key makes a dot or a dash. At first it is read against the speed you set: anything longer than two dots at that speed is a dash, so a single long press is a T. Once your own dots and dashes form two clear groups, the reading follows your timing instead. A pause of three of your dot lengths ends a letter and seven ends a word, and these follow your own spacing too. In practice mode, a pause right on the edge is read the way that fits the word.
With paddles, the keyer times the elements for you: hold the dit paddle for dots, the dah paddle for dashes, and squeeze both to alternate. In mode A the keyer stops when you let go; in mode B it adds one more element of the other kind, the way most contest operators learn.
Keys work only while the key area has focus, so Space still scrolls the page everywhere else, and the paddles let go if you click away.
Tips
- Keep a steady rhythm: consistency matters more than raw speed.
- Aim for a dash about three dots long. The advice under the meters appears once you have sent both.
- Watch the pause meter: leave a clear gap between letters, and a longer one between words.
- Have a real key? A USB adapter that types Space or Ctrl works as a straight key; one that types left and right Ctrl works as paddles. MIDI adapters work too: any note keys the straight key, and for paddles odd notes are dit and even notes dah.
