 This is a fork of the [Havoc](https://github.com/furrtek/portapack-havoc/) firmware, which itself was a fork of the [PortaPack](https://github.com/sharebrained/portapack-hackrf) firmware, an add-on for the [HackRF](http://greatscottgadgets.com/hackrf/). A fork is a derivate, in this case one that has extra features and fixes when compared to the older versions.
