Morse Code One

Every Tool. One Platform.

Settings

Speed, tone and volume are set in each tool, and each tool remembers its own.

Your key or paddles, the adapter they’re plugged into, and a place to test them. Used by Keyer Practice and QSO Practice (under Send) and by Jeopardy.

Learning Track

My Course shows your class schedule and a link to your curriculum.

Keyer Setup

Plug your key or paddles into a Vail or VBand adapter, plug the adapter into this device with USB, and choose your setup below.

Vail adapter tip: if you’ve used vailmorse.com since plugging the adapter in, unplug it and plug it back in. The Vail site switches the adapter to a mode where it stops sending key presses, and it stays that way until it’s replugged.

Test your key

Send anything. The lights show each contact closing, and the decoder below shows the letters it heard.

Key presses and releases appear here as you send.

MIDI not in use.
MIDI log
Messages to and from the adapter appear here when MIDI is the input method.
Keyboard vs MIDI
Shown only if one press arrives by both routes. A Vail adapter in MIDI mode stops sending keyboard presses, so compare the two by recording key clicks and sidetone with a microphone instead.

What's new

Welcome to Morse Code One

Are you taking a Morse code course? My Course (under Course) then shows your class schedule and curriculum. You can change this any time in Settings.

Start with ICR. Until you know each letter by its sound alone, without counting dits and dahs, use the ICR tool (under Copy) almost exclusively. It plays one character at a time and has you name it at once, which is how that instant recognition is built.

Install the app

Installed, Morse Code One gets its own icon and its own window, and it works with no internet connection. Updates arrive automatically whenever you open it while you’re online.

How to install it

  1. Open the app in Microsoft Edge or Google Chrome (Windows, Mac, ChromeOS, or Android) and click Install app — or the install icon at the right end of the browser’s address bar.
  2. On an iPhone or iPad, open it in Safari, tap Share, then Add to Home Screen.
  3. On a Mac with Safari (macOS Sonoma or later), open it and choose File → Add to Dock.
  4. Launch it from your Start menu, dock, or home screen like any other app.
