![]() One nice thing about using a Flex for FT8 is that you can see the signals from other stations on the panadapter as they all startup and shut down each 15 second frame. It starts up automatically and you hardly every need to think about it. It works well and doesn't need much setup. ![]() The utility I use is Dimension4 (so called since time is the fourth dimension). There are utilities that periodically (every 10 minutes or so) synchronize your PC clock to UTC to within a fraction of a second using data from network time servers. ![]() So if your PC is synchronized to UTC (within about 1 second) and so is everyone else's, all our FT8 frames will start at about the same time. An important idea in FT8 is that everyone all over the world starts each 15 second FT8 frame at very nearly the same UTC time, every 15 seconds after the minute.
