Dear Joe,
Thank you for your message.
Can you tell us if this new FT4 mode will be accessible for classic QSOs
(such as FT8, JT65 and JT9) or if it can only be used in contest mode?
My 73,
David F4HTQ.

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)
