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)
