RF Analyzer is an Android application for real-time RF spectrum analysis using SDR hardware such as HackRF, RTL-SDR, Airspy HF+, and HydraSDR. It displays live FFT and waterfall plots, supports analog demodulation modes (CW, AM, FM, SSB), and can record and play back raw IQ data.
Use cases
- analyze rf signals on android with a hackrf or rtl-sdr dongle
- view a live fft and waterfall of the radio spectrum on my phone
- demodulate AM/FM/SSB radio signals with an SDR on mobile
- record and replay raw IQ samples from an SDR
- identify unknown signals and frequencies in the airwaves
- use my phone as a portable spectrum analyzer for ham radio
When to choose
- you want a mobile, touch-optimized SDR spectrum analyzer with waterfall display
- you own HackRF, RTL-SDR, Airspy, or HydraSDR hardware and use an Android phone
- you need demodulation, IQ recording, and bookmarking in a single portable app
When to avoid
- you need a full-featured desktop SDR suite like SDR#, SDR++, or GQRX
- you use iOS or non-Android platforms
- you require digital-mode decoding (e.g., DMR, P25) which is not supported
