"Keeping the sound of Morse alive"

MorseKOB is a program for doing landline telegraphy and American Morse with the help of a computer. For more information on Morse telegraphy, visit the Morse Telegraph Club’s website.

MorseKOB versions

This is the stable version of the KOB program. Completely unchanged since 2009, it’s still the preferred choice for most users. A tutorial and FAQ are available for this version.

This version runs on Mac OS and Linux, in addition to Windows. It’s the obvious choice for Mac and Linux users. It has a few more features than KOB 2.5, but it's not as robust. Not for the faint of heart.

KOB 4.0 is currently under development. If you're interested in serving as a beta tester, please contact us at the address below.
