Just for completeness, I note that I was using using Meinberg on my Mac, and the time differential was 2.1 to 2.3 seconds. I switched to an Apple server in Cupertino (I am in San Diego) and the difference dropped to 0.1 seconds.

I believe the WSJT-X User Guide recommends that you use the closest time server. It takes 0.13 seconds for light to circumnavigate the earth. Add in time for hops and switches, and this sounds like good advice.

Hi to Alan, Brian and Kari,

That is very interesting! I changed the time update period earlier, and that did seem to make a difference. I think I went from 1 minute to 5 minutes, and noticed it didn't drop as much. I will change that to 30 minutes over the weekend, and see whether that improves things.

As for Meinburg vs Dimension4, well, that seems to be one of those things. I know many folk that run D4 happily, and hate Meinburg, and also vice versa, so I will stick with D4 for now.

Thanks for the tips, all much appreciated. I will keep an eye on things, and see what happens.

Very 73

Phil,

Definitely.
Use far less than that, maybe several hours or more unless your PC clock
is broken.

In fact the proper NTP of Meinberg is recommended.
