Listen to several signals within one receiver bandwidth
CubicSDR lets you place several demodulators in a live spectrum, hear selected signals, and record their audio. Bookmarks and tuning controls help revisit stations within the receiver’s available bandwidth.
It uses a SoapySDR driver for the connected receiver. Install the matching HackRF or RTL-SDR module. Blog V4 needs an updated RTL-SDR driver; older Mac packages may need a source build with current drivers. This is a receiver application, not a HackRF transmitter.
