JS8Call version 2.0 has been released
Jordan, KN4CRD has released version 2.0 of JS8Call.
JS8Call is an experiment to test the feasibility of a digital mode with the robustness of FT8, combined with a messaging and network protocol layer for weak signal communication on HF, using keyboard-to-keyboard style 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. Source code can be found in this public repository: https://bitbucket.org/widefido/wsjtx/
- 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
