Very cool application using the excellent HackRF platform demoed at Defcon.
What do you get when you combine one of the best (and certainly one of the best for the price) software defined radios with the user interface of a 10-year-old iPod? The HackRF PortaPack, developed by [Jared Boone], and demonstrated at DEFCON last weekend.
[Jared] is one of the original developers for the HackRF, a 10MHz to 6GHz software defined radio that can also transmit in half duplex. Since the development of the HackRF has (somewhat) wrapped up, [Jared] has been working on the PortaPack, an add-on for the HackRF that turns it into a portable, ARM Cortex M4-powered software defined radio. No, it’s not as powerful as a full computer running GNU Radio, but it does have the capability to listen in on a surprising amount of radio signals.
