    Hey Folks!

    I'm happy to announce that after a few months of development and a month of on air testing, JS8Call 2.0 is now available. You can grab your copy here: http://files.js8call.com/latest.html

    What is JS8Call? It's an open source amateur radio application to communicate using the JS8 digital mode. You can learn more about it here: http://js8call.com

    Why is this 2.0 release so special? Well, it happens to include 3 major features that y'all have been asking for:
    • 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
      • And...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.
    If you've tried JS8Call before, but thought it was too slow... give 2.0 TURBO a try :)

    If you've tried JS8Call before and felt like it was hard to have a conversation one line at a time... give 2.0 typeahead feature a try.

    If you haven't tried JS8Call before, now's the time. There are over 1000 unique callsigns on the air everyday.

    Hope to see you on the air with JS8! Cheers!

    Thanks for all your work on this project. My friends and I have been using your program for over a year now. What a fine program it is today. You really have something now, and I don’t even think of using any other mode for conversation at this point. The faster speeds is just icing on the cake.

    Different frequencies as it is a different mode (meaning, you cannot decode FT8 or similar with JS8Call). Example: 40m frequency is 7.078MHz

    JS8 is a game changer, best thing since sliced bread and PSK31. Actual qso's, get real sig reports as desired, messages to your inbox(like packet of old) and ack on the exchange. The only puzzle is why more have not caught on(maybe all they want is a quick automated exchange). Worldwide keyboard chat with low power and simple antennas.

    TRY IT, YOU'LL LIKE IT. The perfect tonic for a solar minimum.
