The new version of WSJT-X v2.10-rc5 was released yesterday which includes a new FT4 mode. This mode is designed to compete with RTTY for contesting. It uses a 6 second transmission vs. the 15 second transmission of FT8. It definitely feels much faster than FT8 but I personally feel it should be it’s own contest mode vs being used in RTTY contests. We’ll see how it all plays out over time.
