Take a look at the whole supported spectrum: Here we can see the FDD downlink bands used by Salt – small line around 925 MHz – and the two 15 MHz wide of Sunrise and Swisscom – 930-960 MHz: The yellow lines “vibrating” – frequency modulation – between the 92-108 MHz: What can we do FM Radio Broadcaster around

usb 2-1.5: New USB device strings: Mfr=1, Product=2, SerialNumber=4 usb 2-1.5: New USB device found, idVendor=1d50, idProduct=6089 Preparationįirst make sure to have the newest firmware: usb 2-1.5: new high-speed USB device number 5 using ehci-pci This function, called Sweep Mode, scans the entire supported range (1-6000 MHz) in less than 1s more precisely, HackRF is capable to scan at a rate of 8 GHz/s, all for ~300$, thanks to Michael Ossmann. With the last firmware review (2017.02.1), HackRF received the capacity to scan a wide range of frequencies, rapidly retuning the radio clock (before that upgrade, the retuning had to be made externally).

HackRF is a Software Defined Radio, a hardware platform capable of receive/transmit signals in a frequency range between 1 MHz and 6 GHz. A scan of the entire supported range takes just 1 second.
