Listen to or record several radio channels at once
RTLSDR-Airband turns one receiver into several AM or narrowband FM audio channels within its sampled bandwidth. Send audio to local files, a sound server or an Icecast stream, and choose separate frequencies and squelch settings for each channel.
It runs as a headless service, mainly on Linux. Blog V4 needs a compatible librtlsdr driver; macOS builds are less tested. Reception is limited by the receiver’s bandwidth and antenna.
