[bars] WSJT-X tip

[Jonathan Lyna]

 What about the people that want an external hardware device to sync their clock to something like a GPS satellite (an atomic clock in the sky, instead of an atomic clock at the end of a wire)?   A method that uses this would be portable, wouldn't it?   Of course you could sync the clock before you head out manually, or have it always "good to go"  automatically,  but what if you want to synchronize using radio waves, before you FT8 over radio waves?  A fully "wireless" solution.
Could you make a GPS dongle work in these cases?

 Considering that most of our members are older, I think the "set it and forget it" method is much more reasonable than having to remember to sync. It will also help with any other app that requires an accurate clock.

Yes, this method works. However, if you're just an occasional FT-8 (JS8Call, etc.) user (like me), you can skip the regedit method and just sync when necessary through the following:
   
   - Right-click on the clock
   - Left-click "Adjust date/time" (usually near the top)
   - On the Date & time screen (you may have to scroll down a bit) and left-click on the "Sync now" button
Your clock only needs to be with about 500 msec of UTC.
This site www.time.gov will give you a good estimate of the difference between your clock and UTC (the system corrects for network delays).

Subject: [bars] WSJT-X tip One thing FT-8 is sensitive to is your computer's clock, which has to be accurately sync'd with a time server. If you are running on Windows, the default is to update your clock once a week using the NTP protocol and a Microsoft time server. WSJT-X recommends installing software to update more often, but that's not necessary. It's easier to use Regedit. The key to change the auto time sync time interval settings is located at:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient

The key name is SpecialPollInterval and the type is DWORD. The default value is 604800 (decimal) or 0x00093a80 (hexadecimal). That number is the seconds between update. Change the value to 86400 to auto time sync every day. Don't make it much shorter than that or you risk getting blocked for swamping the server with requests. This works on all versions of Windows back to XP.
Windows uses NTP, not SNTP, and you can also change the NTP server it uses here:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters
...in the NTPServer key.
