Here are some .zip files for you to use for CW practice. There are three formats, wav, ogg, and mp3, designed for you to use in your car with an media player. However, you can use these with any player you like, on any platform you like, if the files are compatible.
They are intended for practicing head copy, using instant character recognition, without writing anything down. If you find that you can copy all or almost all of it, then you should go up to the next speed.
Practice files that are 20 WPM and below are Farnsworthified at 25 WPM. This means the text is spaced out at whatever speed, but the characters themselves are at 25 WPM.
If you want the text to read, you can scroll down and get the Texts.zip file.
CW clubs who teach CW curricula may use these file if they see fit.
73, and have fun. - Tom N4LSJ
