After my last video, some of you thought JS8Call was GPS or NTP dependent. Here is a little known feature you may not know about.
When we use JS8Call, we usually synchronize the time to within a few hundred of milliseconds, using either NTP (Network Time Protocol) or with a GPS. This works great until there is no internet, or NATO decides we can’t access GPS satellites. Regardless, there is still a third way (fallback) to keep your JS8Call cycle times, close enough to the correct time, and is completely off grid.
In JS8Call go to Menu>View> Select “Show Time Drift Controls“. In the lower right of your screen you’ll find the image shown above. These controls allow your station to sync start and stop time of JS8Call to the stations your own station can hear. Just choose the number of decode cycles to use for syncing, then click “Start Automatic Time Drift“. One can also manually set the start/stop sync time using these controls.
Take a look and give it a try.
