hackrf_transfer is a command line tool for getting a HackRF to capture and replay IQ files. I often use this for testing software such as FreeDV RADE and digital modes. Playing back a slab of a band full of SSB contacts is a great way to demonstrate receivers such as my Soldersmoke Direct Conversion receiver.

The main window has two main parts. Capture:
The little sound icon in the right top corner monitors levels live before capturing and is useful for setting LNA and baseband gain to optimum values.
Here's Transmit:
Captures made on a HackRF Portapack Mayhem are .c16 files and this software will convert the file and sample rate for playback on macOS.
