WSJT-X implements communication protocols or "modes" called FST4, FST4W, FT4, FT8, JT4, JT9, JT65, Q65, MSK144, and WSPR, as well as one called Echo for detecting and measuring your own …

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.

Oct 11, 2019 · First, what is it? FT8 is one of the many digital modes often referred to as sound card modes (SCM) because they utilize a computer’s sound card to bring in audio from your radio to be …

FT8 is a weak‑signal digital mode designed to make contacts when conditions are poor. Instead of sending speech or Morse, it uses short, tightly defined digital messages transmitted as audio tones …

Apr 9, 2026 · WSJT-X supports the communication protocols FST4, FT4, FT8, JT4, JT9, JT65, Q65, MSK144, WSPR, FST4W, and Echo, each optimized for different sorts of radio-wave propagation.

Next is an example of a QSO in FT8. I initiated a response to a CQ by double clicking the CQ on the Left side of the screen where the incoming decoded messages come in.

FT8 is a popular digital mode used by ham radio operators to make long-distance radio contact. It stands for “Franke-Taylor design, 8-FSK modulation” and uses a transmission method called "8 …
