“The idea with JS8Call is to take the robustness of FT8 mode and layer on a messaging and network protocol for weak signal communication on HF with a keyboard-to-keyboard interface.
JS8Call is heavily inspired by WSJT-X, Fldigi, and FSQCall and would not exist without the hard work and dedication of the many developers in the amateur radio community.”
JS8Call is a derivative of the WSJT-X application, restructured and redesigned for keyboard-to-keyboard message passing. It is not supported by nor endorsed by the WSJT-X development group. While the WSJT-X group maintains copyright over the original work and code, JS8Call is a derivative work licensed under and in accordance with the terms of the GPLv3 license.

As such each version will have a limited lifespan, you should also be aware that there may be bugs in the software and that links on the websites may become out of date at times. If you want a stable version of the software then we ask you to please wait for Version 1.0 to be released.
The reason for the limited lifespan is because older versions of the software may be incompatible with the current release, for this reason we encourage you to sign up to groups.io to stay informed about the latest release Please follow the link https://groups.io/g/js8call to sign up.

Lucky you! I just released JS8Call 2.1 as an early holiday present to y’all. Go grab it here: http://files.js8call.com/latest.html
What’s new? A bunch of bug fixes, of course. But also:
- A new slow speed with a 30 second transmission for decoding down to -28dB. Fire up those milliwatts!
- A software filter to limit the frequencies that the decoder will try to decode. Useful in crowded bands or for slow CPUs.
- Some tweaks to the decoder to allow it to be slightly more sensitive.
Hope to QSO with you over the holidays. Cheers!
