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) Sig The Original Rolling Ball Clock Idle Tyme Idle-Tyme.com http://www.idle-tyme.com On 4/24/2019 12:34 PM, Mike Waters wrote:
Someone on 75m this morning said that there was a new FT-4 mode, meant for contesting. I know nothing about it. 73, Mike www.w0btu.com _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
