“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lifespan, you should also be aware that there may be bugs in the software and that links on the websites may become out of date at times.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.

I’ve just published JS8Call version 2.0 for public release. Grab your copy here: http://files.js8call.com/latest.html and check out the latest information in the guide: https://docs.google.com/document/d/159S4wqMUVdMA7qBgaSWmU-iDI4C9wd4CuWnetN68O9U/edit?pli=1#heading=h.kfnyge37yfr

A big thanks to all of the beta testers who helped me identify and resolve critical issues in 2.0. It’s now very stable and ready for y’all to take it for a spin.

What’s new in 2.0? 

  • Transmissions can now happen at three speeds: NORMAL, FAST, and TURBO. The intent is to start your QSO in NORMAL speed and “upgrade” to higher speeds after evaluating your propagation path to your QSO partner.
    • NORMAL – 50Hz – 16WPM – 15 second transmissions decoded down to -24dB
    • FAST – 80Hz – 24WPM – 10 second transmissions decoded down to -20dB
    • TURBO – 160Hz – 40WPM – 6 second transmissions decoded down to -18dB
  • The new MULTI decoder can decode all three speeds at once.
  • You can now type your messages while transmitting using the new typeahead feature.
  • The notifications system was revamped so you can select an independent sound card for audio notifications.
  • @APRSIS group callsigns for spotting messages to external networks.
    • @APRSIS GRID – will send your position to APRS-IS
    • @APRSIS CMD – will send a raw packet to APRS-IS (an example in the guide)
  • If you have integrated with the JS8Call API, note that the default port has changed to 2242 for better compatibility with other software.
  • Added support for newlines in messages (Shift+Enter while typing)
  • Added partial (uppercase) support for Latin-1 characters.
  • Many bugfixes, small feature improvements, and more: http://files.js8call.com/changelog.txt

If you run into any issues, be sure to submit them to the issue tracker: https://bitbucket.org/widefido/js8call/issues?status=new&status=open

In the meantime, I hope to see y’all on the air! 73!
