A FT4 Strangeness ...

    I've been using FT4 for some time now, and in operating from the EU just now, but I'm experiencing something I've not seen before, namely that after a CQ'ing station responds to my call, my side sits for a full 15 seconds before replying with the next message, rather than in the next 7-second time frame interval. This makes about half of the stations I initially connect with - go on to someone else thinking that I've faded away.

    I'm getting the impression that WSJT-X doesn't always set the odd/even cycle check correctly.

    Ideas?

    Computerized ham radio isn't perfect, regardless of the implementation of the computer. Pick up a mic and call CQ instead?

    You haven't worked me on phone, far from perfect. ;)

    Check your computer clock is still syncing with whatever source you choose.

    There is a registry hack for Windows that makes the computer sync up daily, I guess weekly is the default.

    That's my 1 idea.

    Dim4, install it and never have to adjust your clock again

    Don't think this is a clock issue. I have the same thing happen once in a while. Have checked the clock when it happens and hasn't been off by more than a half-second.

    I can't make it appear at will, and will often go days without seeing it and it will suddenly pop up once, then go back to normal for days or weeks to come.

    May not have any bearing, but running a "minimal" station here. Older dual-core AMD at 3 GHz with only 4G RAM over USB cable to IC-7200. Still, it doesn't overtax the CPU or RAM. I just can't play "Hunt the Wumpus" while I operate!

    I don't think it's a clock issue either. The time differentials are all around 0.0 to 0.2 simply listening to other stations.

    I have two examples, one normal and the other exhibiting the "weirdness". The normal QSO completes in what appears to be 28 seconds as below:

    The weird QSO starts out poorly with two different transmissions occuring at the same time (how can that happen?), which seems too throw the entire QSO off. Notice the 22 second response gap when my first "R-03" is sent.

    My transmission at the time 101415 was "forced" by clicking the odd/even transmit cycle - to "force" a conclusion to this QSO that appeared to be hung.

    I have seen this and can reproduce it. It ONLY occurs for me when the TX Even/1st box is checked.
    I started a thread on it some time ago... Wsjt-x 2.1 oddity.

    If you watch you can see the software actually uncheck the TX Even/1st box and then miss
    sending in the appropriate slot. I then have to hurriedly recheck the box so the QSO can proceed.
