For years, the computer to radio interface has been serial cables (RS-232C) even though NO current computers come with serial ports any more. We are finally seeing technology advances in ham radio. Pretty slick!įinally, for some more great ham radio programs, check out the author's web site. Click on one of the six time zones (such as MDT for Utah) and that becomes the featured time zone displayed next to the UTC time. The first one listed, actually clock #2, shows UTC and all six US time zone.

In addition to sync commands, that will need to be manually executed, we selected for you some of the most popular programs used by hams, that you can easily install on your PC in order to accurately and continuously sync your computer clock with internet NTP servers.Here are some nice UTC clocks that also show your home time zone.

Windows time sync command net time \ /set /y Mac OSX time sync command sudo sntp -sS Linux time sync command ntpdate -u Computer Time Sync Software Once you have selected one, you can then execute the sync command as in the examples below, just changing the address we use in the examples below. You can find a list of NTP servers on these web sites.

Said that, we suggest you to choose the closest to you. They are often very accurate ther are hundreds of them in the net. NTP servers are internet services whose job is to provide the current time. Time services are provided in Internet by Network Time Protocol Servers.

These commands will time sync your PC with internet NTP time servers. However, under modern Microsoft and Apple operative systems like Windows 10 or MacOSX 10.x you can use a simple commands from Command Prompt or Terminal.

Time synchronization in modern operative systems is often built-in, but some times, difference of even half a second may be the cause of problems on decoding signals.

If you pay attention to the graph, and you see green lines overlapping descending most of the signals, it will mean that your clock is not in sync, and no signals will be therefore decoded.įT4 signals with an accurate time syncronization How to sync computer time with internet If you will be able to decode signals, it will mean that you are almost in time sync, and therefore, you don’t really need an additional synchronization. In case you have no internet access, and want to know if your PC is in time sync, try starting from your PC a weak signal software, for instance, WSJT-X or JTDX session and tune into a FT8 Frequency. According to time.is current UTC time is: The ham radio way How to know if your computer is perfectly syncronized.Ī very simple way to know if your PC Clock is synchronized, is to visit the Time.is web site and check the difference with your PC clock. Synchronizing your computer time it may be very easy task, and sometimes a challenge. Time sync has become a so important factor, that makes the difference between being able to make contacts and not to be able. Nowadays, in the weak-signals digital modes era, with time synchronized protocols like FT8 FT4 JT65 and JT9, an accurate time synchronization of your PC clock with an atomic time service has become mandatory. In classic amateur radio operations, the need of a good time synchronization has always been a requirement, for contact logging purposes, or for example in APRS and packet radio systems.
