When using digital over the radio, it is particularly important you have the correct time. Even a second out will stop you from making contacts. I relied on Windows to update the time and got an email from a helpful amateur telling me my time was out. You can see below it wasn’t out by much but was enough to stop me in my tracks!
So, I installed NetTime at https://timesynctool.com/ but there are a few things you should do.
This free program will update your time on your PC to be exactly the right time. After you install it, go to the settings, and change the update interval to 15 minutes rather than the default 12 hours.
It is a simple little program, not much to it, but sure helps you keep the correct time down to the second.
After you have done this, you should be right to go!
