What can the HackRF One actually do?

It receives and transmits radio signals from about 1 MHz to 6 GHz over USB. It is used for signal analysis, protocol testing and SDR learning, not as a finished scanner.

Do I need a license to transmit?

Yes, in most countries and bands. Transmitting outside allowed frequencies or power limits is illegal; many owners use it to receive only.

Does it come with an antenna?

No. You need to supply an antenna matched to the band you want to listen to or transmit on.

Can it transmit and receive at the same time?

No. It is half-duplex, so it switches between transmit and receive rather than doing both at once.

What software does it work with?

It works with SDR#, GNU Radio and other SDR tools, and HackRF's own software is open source on GitHub.

Our take on the HackRF One

The HackRF One is an open-source software-defined radio transceiver that tunes from about 1 MHz to 6 GHz, so it can receive and transmit across a very wide slice of the radio spectrum. It connects over high-speed USB, runs on USB bus power, and works with SDR# and GNU Radio. It is a development and testing board, not a finished scanner. At $439.95 at Amazon as of November 5, 2026, it sits at the top of its recent range; three stores list it new.
