American Morse Code Trainer

Practise copying and sending American Morse code using a scheme of sessions adapted with permission from Rob Brownstein's CWops CW Academy scheme. Please note that this should not be confused with the official CWops CW Academy beginners' training tool for International Morse.

Personalisation

For some of the sessions some additional information is needed. This information is not sent to nor stored on the server.

Session

Choose your session and then practise the copying and sending segments.

/

Play each of these segments again and again until you feel you recognise the sound pattern. Click on word tiles to hear them separately.

Text to copy

/

Play a segment, then try to imitate it, exactly, using your key or keyer. Repeat it as many times as it takes to feel that you’ve got the correct word pattern.

Text to send

/

If you need to practise any other sequences then enter them below. If you want to use prosigns then enclose them with angle-brackets (e.g. "<bk>").

Choose the letters you want to practise:

The letters above are shuffled to make “words” of characters,
each repeated times.
The “sentence” will have words.

Notes

Please enable cookies on this site to store your preferences between training sessions.

There are many keyboard shortcuts which can also access additional functions such as playing the next segment. Press ? to list them.

This tool is known to work well in recent Chrome, Firefox, Safari and Edge web browsers, including mobile versions (which implement the Web Audio API and can be downloaded here).

The download buttons download a WAV file of the sound for the segment displayed with a pause at the end defined by the segment gap. Safari does not properly support the download buttons but they can be made to work in the desktop version by holding the Option key when clicking them and then saving the file with the ".wav" file extension.
