Locked Re: WSJT-X No Decode

I do not see how this would help much. If at start timeis tells you that you are too far off you still have to fix it. I have used dimension 4 and cannot remember the last time any of 3 computers were off by more than 50 milliseconds. If you are a user of something as complex as WSJTX then it seems you are more than competent to be sure that your time is correct. I also do mot want more than one time sync app trying to fight with another which could happen.

This is such a common problem... I wonder whether the maintainers of https://time.is would permit WSJT-X to make use of their API, so that on startup, and periodically thereafter, WSJT-X could show you how close to ‘correct’ time you are?



 Time.is is made for humans. Automatic refresh and any usage from within scripts and apps is forbidden. If you need time synchronization for your app, please contact us about our API.”

I’m thinking of just notifying you of the time difference on startup, not automatically synchronising.. 

The alternative could be to embed an NTP client in WSJT-X (and configuring a set of common ‘pool’ servers). This would be much more involved; time.is is likely to have a relatively straightforward REST API, versus the complexity of the NTP protocol.

You can use the website Time.IS which will tell you whether or not your computer is correct.

Check your computer clock with some reference.   While Windows does provide a time service, I've found it is not adequately accurate for WSJT-X and FT-8 modes.   I personally use a free software Meinberg to keep the computer time in sync with the rest of the world.  My decode DT values are most always >0.5 seconds.

Something has happened to my WSJT-X setup, I no longer get Decodes.  The Waterfall has a large number of FT8 signals displayed.  The Decode button is Green,  The Audio paths have not changed.  The TX path seems to work as I hear tones with the TX audio monitor on the radio turned on.  I am running Windows 10 and just installed WSJT-X v2.1.2.  The problem started before I did that upgrade but hoped maybe it would fix the problem.  Not sure where to look next, need help?
