I just bought the hackrf one and have it set up to use in SDR# but I'm not sure that it's working correctly. Do I need to download any hackrf tools to use with? Or did it just come equipped?
Knowing what you are trying to accomplish with the device would be helpful. SDR# has supported HackRF One as a receive source natively for quite some time.
When I had my HackRFOne I used it with SDR# with no changes. However, since AirSpy has taken over SDR# not sure if that still is the case. I do remember the HackRFone working well on HF using my 31 foot outside vertical antenna. Your HF reception will depend on your antenna.
