FT8
FT8 (short for Franke–Taylor design, 8-FSK modulation) is a frequency shift keying digital mode of radio communication used by amateur radio operators worldwide. It was released on June 29, 2017, by its creators Joe Taylor, K1JT and Steve Franke, K9AN, as part of the WSJT software package.
FT8 was adopted quickly, becoming the most widely used digital mode reported by automatic spotting networks such as PSK Reporter within two years.
