Nexus

Nexus is a free, open-source desktop application for amateur radio operators that combines decoding, logging, mapping, alerting, propagation tracking and spectrum display in a single program. It supports fifteen modes including FT8, FT4, CW, SSB, FM, RTTY, SSTV and APRS with both transmit and receive capability. Built in Rust with a Tauri desktop shell, Nexus runs on Windows, macOS, Linux and Raspberry Pi from one codebase. It includes real rig control via CAT, DXCC/WAS/WAZ award computation offline, live APRS mapping, propagation globe, and integrates with LoTW, QRZ and ClubLog. Designed for radio operators who typically run multiple separate applications, Nexus consolidates these into one interface with shared radio control and logbook.
