About LCWO - Learn CW Online

This site, Learn CW Online (LCWO), was established in May 2008 by Fabian Kurz, DJ1YFK (Impressum, profile), hoping to make learning and practicing CW (Morse code) as easy and effortless as possible.

LCWO is under constant development; all comments and suggestions are welcome. To get in touch with the author, use the contact form or send an email to help@lcwo.net. For general questions and discussion, feel free to use the forum. Thanks to all the users who contributed to the project so far. Without all the feedback the site wouldn't be what it is today!

Using LCWO is and will always remain free of cost. We are not interested in monetary donations.

Press release

Feel free to use the following announcement of LCWO for your club newsletter, website, blog, etc.

A new website to learn and practice Morse telegraphy has been launched:
http://lcwo.net/ - Learn CW Online

There are already hundreds of training programs, MP3/CD courses and practice
aids available, but LCWO follows a radically different concept: While sticking
to  well-proven methods for learning and practice, all you need for using LCWO
is a web browser!

This gives the user the liberty to practice CW wherever an internet connection
is available, always retaining the personal settings, scores and statistics.

Currently the site, which is available in 29 languages offers a complete
Koch method Morse course, code group practice, callsign- and plain text training
modes and also allows to convert random text to Morse MP3s.

A high score list is available to compare results with other users, personal
statistics help to track training progress.

LCWO.net is a non-commercial project. Creating a free account only takes a few
seconds, and you can start practicing CW right away!

Browser compatibility, technical stuff

LCWO supports most modern browsers, in particular the latest two generations of Mozilla Firefox and the Microsoft Internet Explorer, but has also been reported to work with Opera and Apple's Safari.

To enjoy all features of LCWO, JavaScript needs to be enabled and either a HTML5 compatible browser or using the Adobe Flash Player for CW playback is highly recommended.

Development of LCWO takes place under Debian GNU/Linux and Ubuntu, using the fantastic vim editor. The site runs on an Apache Webserver, is mostly programmed in PHP (without any frameworks, all homebrew) and uses a MySQL database. The Morse MP3 and OGG files are generated by customized versions of ebook2cw which run as compiled CGIs, written in C.
