FT8 is a digital communication mode used in amateur radio, designed for weak signal communication. It was developed by Joe Taylor, K1JT and his team as part of the WSJT-X software suite. FT8 allows operators to exchange information quickly and efficiently, even under challenging conditions, by using short 15-second transmission intervals. The mode is particularly popular for its ability to work in low signal-to-noise ratios, making it ideal for long-distance communication. FT8 operates on various amateur radio bands and is widely used in contests and casual contacts, helping enthusiasts connect across the globe.
