Nexus Ham Radio
Free, open-source ham radio workstation — FT8/FT4, phone, CW, prop
Nexus brings the whole ham station — FT8/FT4, phone, CW, satellites, propagation, logging, and awards — into one modern Windows app a new Technician can set up in minutes and a seasoned DXer won't outgrow.
A 3-step wizard detects your rig (USB or FlexRadio LAN), sets CAT and audio, and won't transmit outside your licensed segment; ~50 rigs + Hamlib bundled. FT8/FT4 sequencing built to WSJT-X, a sortable roster with country/worked-before/LoTW flags, one-click work-it. Band-opening detector anchored to your station, a native ITU-R P.533 engine, and a 3-D greyline globe. The Needed board ranks callers by log value with proof the path is real. Phone bandscope + voice keyer; CW keyer + live decoder; satellites with rotor auto-track. Speaks WSJT-X UDP so GridTracker/JTAlert/loggers work; LoTW/QRZ/ClubLog/eQSL/N1MM.
Also debuts FT1/DX1 — experimental 4-second weak-signal modes, simulation-validated, not yet on-air-proven. Open beta; unsigned installer — verify the SHA-256. GPL-3.0.
