Sweep++ Sees More of the Radio Spectrum at Once
An open-source spectrum analyser that uses software-defined radios to sweep wide bands, identify signals, and replay recorded scans.
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.
