There is an icon in the system tray that shows the current status. Once installed, the software runs in the background to keep the computer clock updated. It was very easy to set up the software to work with the GPS receiver. On my computer, the GPS receiver is the Prolific USB-to-Serial Comm Port (COM4).Īfter the GPS receiver, I installed the NMEATime2 software. I have the receiver in a windowsill near the computer.

The GPS receiver connects to a USB port on the computer as a serial device. The GPS receiver cost me $34, and it also cost me $20 to register the software. To do this, you need the software and a GPS receiver for the computer.įor my computer, I use a GlobalSat BU-353-S4 USB GPS Receiver and NMEATime2 software for GPS-PC time synchronization. Dimension 4 periodically updates the computer clock using a low level internet protocol, called SNTP, to connect with special purpose Internet Time Servers.īut what if you don’t have Internet access, due to an outage or working in the field? Fortunately, there are computer applications that will synchronize your clock using GPS signals. I have Dimension 4 loaded on my shack computer. Some examples are Meinburg NTP, BktimeSynch, Dimension 4, and NetTime.

There are also several applications that will connect to Internet time servers to periodically update the computer clock.
Recent versions of Windows will frequently update the clock through time servers, but the updates are not usually as frequent or accurate as I would like. This is well within specs for digital modes. A check of my computer’s clock on time.is showed that it was 0.3 seconds behind.
It is very easy to check the accuracy of your computer’s clock by using the website time.is. While millisecond accuracy is not necessary, if the computer clock is off by more than a second, you are likely to experience problems. Accurate computer time is absolutely essential for successful QSOs using digital modes such as FT8, FT4 and JS8.
