The following is a press release from hamradiotools.io:
HAMRADIOTOOLS.IO, Nov. 8, 2026. Nexus, the free, open-source (GPL-3.0) amateur radio station program by Seth McCallister, KD9TAW, has released version 1.22.0. During M- and X-class solar flares, Nexus now draws NOAA’s D-RAP (D-Region Absorption Prediction) map on its flat map, globe and 3-D globe. Rings around the point under the sun show, band by band, where HF is weakened and where it is out. A flare chip gives NOAA’s start and peak times, which bands are out under the sun and at the operator’s QTH, and how long until HF recovers. Below M class the map stays quiet.
When NOAA issues a geomagnetic storm watch, Nexus counts it down and reports the arrival only once the solar-wind monitor at L1 measures it.
The release also tells operators which way round the world a path goes. Using the ITU-R P.533 propagation engine, the Path card suggests short path or long path, with a beam heading. The release notes say this is advice from a monthly-median model. The long path is modelled and is never called more than “possible.”
Nexus 1.22.0 also adds a Russian translation by volunteer translator loloka.
Existing users: in-app updating did not work on the stable channel before this release. Install 1.22.0 once from the download page, and later updates will come through Nexus.
Nexus is free for Windows, macOS, Linux and Raspberry Pi.
