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)
