Ein neue, schnellere und contestfreundliche Sendeart ist – zunächst in der Betaversion – nur wenige Tage von seiner Veröffentlichung entfernt. Wie die WSJT-X-Entwickler Joe Taylor, K1JT; Steve Franke, K9AN, und Bill Somerville, G4WJ, mitteilten, handelt es sich bei FT4 um einen experimentellen Digimode, der speziell für Conteste entwickelt wurde, und dessen Sende-Empfangs-Sequenzen lediglich 6 Sekunden und damit 2,5-mal schneller als bei FT8 dauern sollen.

Das Entwicklerteam erklärte, dass man mit der Entwicklung des neuen FT4-Protokolls kurz nach der FT8-Überarbeitung vom 1. bis 2. Dezember 2018 begonnen haben. FT4 soll in Kürze von einer größeren Gruppe getestet werden können. Es werden interessierte Teilnehmer gesucht, die ihr „überlegtes Feedback“ anbieten können. „Wir planen, am Montag, den 29. April, herunterladbare Installationspakete für WSJT-X in der Version 2.1.0-rc5 (-rc-Versionen sind so genannte Release-Candidate-Software) zu veröffentlichen“, teilte die Entwicklungsgruppe zum Startdatum von FT4 mit. Weitere Informationen zu FT4 erhält man unter: http://physics.princeton.edu/pulsar/k1jt/FT4_Protocol.pdf
