Yes, there is a utility http://www.dxshell.com/jtsync.html that will do exactly what you want. It syncs either via ntp or if there is no network it is using a very clever methode do average received FT8/FT4 signals to set your clock. Extreme late or early transmissions in time are ignored. 73s Wolfgang OE1MWW -------- Ursprüngliche Nachricht -------- Von: Paul Bramscher via wsjt-devel <wsjt-devel@lists.sourceforge.net> Datum: So., 18.

I was at a monthly outdoor ham event in the greater St. Paul/Minneapolis area that's drawn loyal attendance the past few years. An operator setup FT8 outdoors, but had some issues getting it to decode. We could tell it was getting sound from his port, but there was no decoding. He was using Windows, whereas I'm Linux only so wasn't much help. Another ham suggested he compare his system clock with his cellphone, and that fixed it. I believe he said he was off by 5+ seconds. I'm wondering whether it might be possible, algorithmically to somehow detect that a person's clock may be out of sync and present a notification message. Of course there's the DT/Time Delta column when you are able to decode. But, presumably, he had reached the point of no return. I don't know how this might be possible without an accurate reference clock -- but possibly based on the average timing of heard signals, or some sort of signature within them, to cause a message to the user that s/he may want to check their clock's accuracy? Just wondering what might be possible in this regard, and I suspect it would help portable users, especially those who've been offline for a number of days/etc. and their system clocks had degraded. 73, KD0KZE / Paul _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
