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

Note: there is a newer CW Generator page that you can use.

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>").

Note: there is a newer and better Instant Character Recognition tool which may be used.

Choose the letters you want to practise:
