..and the WSJT musical chairs performance moves on.
At least THIS "experimental" mode is going to have a timer in it's alpha release that will force it to stop working right before the June VHF contest...

"FT4 is an experimental digital mode designed specifically for radio contesting. Like FT8, it uses fixed-length transmissions, structured messages with formats optimized for minimal QSOs, and strong forward error correction. T/R sequences are 6 seconds long, so FT4 is 2.5 × faster than FT8 and about the same
speed as RTTY for radio contesting. FT4 can work with signals 10 dB weaker than needed for RTTY, while using much less bandwidth."
