Nexus is a free, GPLv3, all-mode amateur radio operations center for the desktop. It puts a WSJT-X-parity FT8/FT4 cockpit, seven more WSJT-X modes that transmit as well as receive, RTTY, SSTV, APRS with a live symbol map and an iGate, a CW keying station with an AI decoder (DeepCW model by e04), an SSB phone cockpit with a real RF panadapter, a live propagation map, an evidence-backed "work this now" board, a POTA/SOTA hunter, a club-ready Field Day mode, satellites with rotor tracking, and a DXCC-first logbook with LoTW / QRZ / ClubLog / eQSL connectors into one window, across up to three radios, with one log.

It is built in Rust (DSP, sequencing, CAT, networking) behind a Tauri desktop shell, and it treats WSJT-X as the golden standard for FT8/FT4 behavior. The auto-sequencer state machine, decode cadence, split handling, Hound mode, and the UDP ecosystem protocol all match stock, so your WSJT-X muscle memory works unchanged inside a UI built this decade.
