The HackRF PortaPack is a portable LCD screen with control interface and processor that connects to a HackRF software defined radio. The PortaPack’s goal is to allow for portable RF spectrum visualization, tuning and eventually demodulation of many modes. It has been in development from around the time of the August 2013 HackRF kickstarter and is now almost ready to be shipped out to the initial backers. For more information about the PortaPack see this Hak5 segment that we previously posted about where Jared Boone the inventor of the PortaPack is interviewed.

Getting the PortaPack H1 ready for shipping was a long slog. And as is my way, I took a lot of detours along the way. I incorporated a lightweight operating system (ChibiOS) into the firmware. I built a simple UI framework that would support arrow-key navigation, with touch as an option where appropriate. I developed a sophisticated test jig (based on this) to ensure the units I ship work correctly. I designed a milled aluminum case that I’ll offer as an option. And I finished and tested all the units myself, including doing failure analysis on a bunch of PortaPacks. I learned a great deal, and hope that my next product development cycle will be much easier and faster.
Because of all the manufacturing effort, work on the firmware hasn’t advanced very far. At this point, the PortaPack is mostly useful as a basic narrowband AM/FM receiver. But there’s still a lot of capability to be tapped in the HackRF ARM processors! I’m eager to get back to firmware, and implement more signal analysis and capture functionality, along with some digital modes demodulation and decoding support.
