    Yes, I figured that one out immediately. As far as feedback, I've given more than my fair share of that, and feel as if it's fallen on deaf ears.

    We do agree on one thing though, When calling CQ DX, why must nearby people respond!?!?

    If you like FT8 you'll love JS8

    I always call "CQ RARE DX", that at least makes them think twice ... :rolleyes:

    Imagine when the JS8CALL is actually released (Formally), Right now it is still on the pilot phase.

    Wait later today, JS8CALL increases, to 2nd place, but in any case, this mode, working at -24dB below the noise floor at 20wpm, will have an appeal, especially when it is officially launched

    I don't know of any other digital mode, that can make that claim (-24dB below the noise floor. , at 20wpm, using only 50hz of bandwidth), hence once this is released, it will grow exponentially.

    Cheers, NN2X, Tom

    Well, I gave it a good test for some weeks and I think 20wpm is a hollow claim in my experience. Also, keep in mind, PSK Reporter count is based on CQs received by reporting stations, not total activity.

    Which version of JS8CALL you have? The earlier versions (FT8CALL and I believe early JS8CALL), could only do 10wpm, so you might have an older version.

    The latest version can work at 20wpm...

    More choices at the end, and I predict there will be more enhancements, but what is smart about JS8CALL, it is similar to FT8. (But with a QSO)

    NN2X, Tom
