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:
http://physics.princeton.edu/pulsar/k1jt/FT4_Protocol.pdf

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)
