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
Then, install some SDR or signal analysis/manipulation tools, like gnuradio, gqrx, Audacity, rtl_*, and so on. hackrf 2-1.5:1.0: SDR API is still slightly experimental and functionality changes may follow hackrf 2-1.5:1.0: Registered as swradio1 hackrf 2-1.5:1.0: Registered as swradio0 usb 2-1.5: Manufacturer: Great Scott Gadgets 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.
