To: WSJT-X users interested in testing FT4
From: K1JT, K9AN, and G4WJS
Soon after the "FT8 Roundup" held on December 1-2, 2018, we started serious
work on a faster, more contest-friendly digital mode that can compete with
RTTY-contesting QSO rates while preserving many of the benefits of FT8. The
result is FT4 -- a new digital mode specifically designed for radio
contesting.
Over the past month a small group of volunteers have been conducting
on-the-air tests of FT4. The early tests were very successful and helped us
to make a number of important design decisions. We believe
FT4 has considerable promise for its intended purpose.
We'll soon be ready for testing by a larger group. If you might be
interested in participating and offering your considered feedback, please
read the descriptive document "The FT4 Protocol for Digital Contesting",
posted here:

We plan to post downloadable installation packages for WSJT-X 2.1.0-rc5 on
April 29, one week from today. The document linked above includes
- Instructions for installing WSJT-X 2.1.0-rc5 and FT4 configuration
- Operating instructions for FT4
- Basic description of the FT4 protocol, modulation, and waveform
- Detailed sensitivity measurements for FT4 under a wide variety of
simulated propagation conditions
- Schedule for upcoming test sessions
Please consider helping us to make FT4 a successful mode for digital
contesting
With best wishes and 73,
-- Joe (K1JT), Steve (K9AN), and Bill (G4WJS)

Someone on 75m this morning said that there was a new FT-4 mode, meant for
contesting. I know nothing about it.
