WSJT-X (FT1)

WSJT-X (FT1) is a fork of the venerable WSJT-X that integrates the FT1 weak-signal mode directly into the application thousands of operators already use for FT8, FT4, and friends.

The goal is a low-friction on-ramp: rather than asking operators to learn a brand-new program, FT1 lands inside the familiar WSJT-X waterfall, decode window, and logging workflow.

What’s in the fork

• The FT1 encoder/decoder wired into WSJT-X’s C++ audio and UI pipeline.
• Mode selection alongside the existing modes, so you can switch into FT1 as easily as any other.
• Shared DSP lineage with the FT1 reference implementation.

This is part of the FT1 ecosystem — the reference mode, this WSJT-X integration, and the chat-first Tempo app all share the same weak-signal core.

Being a fork of GPL’d WSJT-X, the project carries the same open-source spirit. Expect active development as FT1 matures.
