Starting Digital Modes (HF/VHF) Area
Time - Computer Setup
Do run most digital modes you will be required to have an accurate time measurement on your computer system. If you use the 'standard Windows' setup you will fail ! So let's modify your computer time settings to get time updates from a valid public time server.
- Lets initially test your computer as is to see how it is doing. Open any web browser. In the URL address field enter: time.is What is your time comparison to the time.is site? It is under the 'Your time' above the clock. So lets change your system time server update to get a more accurate time.
- Let's run the time.is check again. If it is still running in your browser, hit 'F5' to reload the page. Your time should now be more accurate and it will automatically update to keep it accurate in the future (assuming you have an internet connetion, as that is how it updates). My systems run within a few hundredths of a second while connected and a few tenths of a second for short times when I do not have the internet connections available.
Go to: Meinberg NTP Download Software and select 'NTP for Windows XP and newer, with IPv6 support'. This is currently v.4.2.8p11 (May, 2018). I suggest you make a directory on your C: drive called 'tools' and run the program and install it into the tools subdirectory.
Create a an initial configuration by checking the tick box. IMPORTANT: Choose the correct location in the drop down list, I use 'North America/United States'. Tick the box for 'fast initial sync mode' (uses a 'burst mode'). In the next box use the 'system' type and continue. Defaults work for all the other settings. Finish the installation and exit.
On Windows 10 (and newer), that should be all that is required. Some older versions require you to go into Control Panel and then time setting and turn off the Internet Time Synchronization.
Your computer system time will now be accurate enough to work with the digital mode software you choose.
