Gqrx
AppTune, hear and record radio signals on a computer
Gqrx combines a live spectrum and waterfall with receiver controls for tuning and demodulating radio signals. Save audio or IQ recordings and return to useful frequencies through bookmarks.
Install the driver for your exact receiver and choose it in Gqrx. HackRF One uses its host driver; RTL-SDR Blog V4 needs a V4-capable RTL-SDR driver. Gqrx is a receiver application and does not expose HackRF transmit features.
