[Elecraft] Remote Operating Time Sync

[Walter Underwood]

Can you get internet by tethering to your phone? If so, the computer should sync with NTP pretty quickly, then hold to within a second while you are operating.

You might be able to force a sync by opening the Date & Time control panel in System Preferences. MacOS uses NTP by default. If that doesn’t work, I’d unlock the panel, uncheck “Set date and time automatically”, then recheck it.

If you are of the shell persuasion, this will do the trick.

sudo ntpdate -u time.apple.com

This software is very time sync critical - the computer clock needs to be within +- one second accuracy. Here at home on my wireless network connected to our cable company, works great.

I completely forgot that the laptop clock would not keep that sort of accuracy without having Internet access. I saw many signals, but WSJT-X decoded nothing at first. Luckily I realized what was happening and was able to access and connect to the WiFi network at the resort we were staying at. This connection provided the accuracy the software needed and all was good.
