WSJT-X 2.3.0 GA Release

/

The WSJT Development Group is pleased to announce the general availability (GA) release of WSJT-X Version 2.3.0.

Upgrading from earlier versions of WSJT-X should be seamless. There is no need to uninstall a previous version or move any files. Links to installation packages for Windows, Linux, and Macintosh are available here - https://physics.princeton.edu/pulsar/k1jt/wsjtx.htm

It may take a short time for the SourceForge site to be updated. You may be interested to know that, somewhat unusually, a release candidate for Version 2.4.0 of WSJT-X will also be made available very soon.

Its main new feature is a new mode called Q65 with unique capabilities for EME and scatter propagation modes.

A summary of new features can be found in the WSJT-X 2.3 User Guide -https://physics.princeton.edu/…/wsjtx-main-2.3.0_en

Launch of Amateur Radio Network

/

John Rivers G0GCQ and Andy Whybrow M0IRU have come together to create the Amateur Radio Network.

This is a new collaboration to create a network to share ideas, engage and discuss all and any amateur radio topics on various social media platforms. Speakers have already been arranged via zoom, including

  • 11th Feb - Tim Duffy (K3LR) CEO of DX Engineering

  • 25th Feb - An evening with Rich Donahue (K0PIR)

  • 11th March - Andy Carpenter of SDRPlay

  • 25th March - An Evening with Jason (KC5HWB)

For the oncoming months, we have Ceecom Antennas, Begali and Yaesu USA in the pipeline.

New WSJT mode Q65

New WSJT mode Q65

WSJT-X 2.4.0 will introduce Q65, a digital protocol designed for minimal two-way QSOs over especially difficult propagation paths

On paths with Doppler spread more than a few Hz, the weak-signal performance of Q65 is the best among all WSJT-X modes. Q65 is particularly effective for tropospheric scatter, ionospheric scatter, and EME on VHF and higher bands, as well as other types of fast-fading signals.

Q65 uses 65-tone frequency-shift keying and builds on the demonstrated weak-signal strengths of QRA64, a mode introduced to WSJT-X in 2016. Q65 differs from QRA64 in the following important ways:
