locked sticky WSJT-X 2.4.0 GA Release #general


We are pleased to announce the General Availability (GA) release of WSJT-X version 2.4.0, which includes the new digital mode Q65.

Q65 is designed for two-way QSOs over especially difficult propagation paths including ionospheric scatter, troposcatter, rain scatter, TEP, EME, and other types of fast-fading signals. Details and recommendations concerning the Q65 submodes are provided in the "Quick-Start Guide to Q65", available here:

The WSJT-X User Guide includes further details about Q65 and is available here: https://www.physics.princeton.edu/pulsar/K1JT/wsjtx-doc/wsjtx-main-2.4.0.html

WSJT-X for Windows now ships with Hamlib version 4.2 as a dynamic link library (DLL). This change will allow Hamlib bug fixes to be resolved by replacing the DLL with an updated version.
