Editorial interest 82/100 Selection signal · not a rating of the site

An open-source spectrum analyser that uses software-defined radios to sweep wide bands, identify signals, and replay recorded scans.

Landing page captured for the 2026-09-15 issue.

Field notes

The application combines repeated radio scans into a single spectrum and waterfall, allowing users to inspect ranges that exceed the instantaneous bandwidth of their hardware. It supports separate ranges in one pass, with 12 built-in presets and labels for Wi-Fi, cellular, LoRa/ISM, FPV, and beacon channels. Scans can be exported as CSV activity histories or saved as .sweeps files for replay, while drivers, FFT engines, and band plans are handled through plugins.
