We are pleased to announce availability of a release candidate for
WSJT-X 2.4.0, introducing a new digital mode called Q65. Timing of this
release is unusual as it follows so closely the General Availability
(GA) release of WSJT-X 2.3.0. This timing anomaly occurs because
development of new modes FST4 and FST4W (in v2.3.0) and Q65 (in 2.4.0)
took place in parallel.
Q65 is designed for making two-way QSOs over especially difficult
propagation paths such as troposcatter, ionospheric scatter, rain
scatter, EME, and other types fast-fading signals. Full details about
Q65 submodes and their capabilities are provided in the Quick-Start
Guide to Q65, available here:
https://physics.princeton.edu/pulsar/k1jt/Q65_Quick_Start.pdf
The main User Guide has not yet been updated with documentation for Q65.
Use the Quick-Start Guide, in the meantime.
