Upgrading HackRF One to PortaPack H2

PortaPack H2 Capture

I just received a very exciting upgrade for my HackRF One. It is called the PortaPack H2. It essentially gives your HackRF a rechargeable battery, a touchscreen display and many new capabilities that are a part of the Havoc firmware.

This setup will basically take my HackRF’s capabilities completely mobile opening it up to places and locations to explore that aren’t easy/possible without a setup like this.

Today I wanted to build the new PortaPack H2 and show all the steps I took. Let’s begin!

Use HackRF SDR to Lock / Unlock Car

CubicSDR - Lock / Unlock Intercept

I’ve previously covered getting your HackRF set up in Linux and getting the firmware updated. In that guide we installed the very easy to use CubicSDR application and were able to easily tune to various audio signals.

Today we’re going to do something more interactive and actually use the transmitter. We’re going to unlock and lock my vehicle using the HackRF! Let’s get started.

HackRF Software Defined Radio Guide for Linux

Cubic SDR - Main Screen

The term “software defined radio” simply means that parts of a radio that were traditionally hardware are implemented in software. This means that functions that used to require knobs, dials or some kind of physical mechanism can now be controlled via software. Essentially this makes using computers/ software with radios much easier and more accessible (cheaper) than it had ever been traditionally.

Now with that background I can explain what the HackRF device is. The HackRF is a software defined radio device that is designed to let you access *all* of the radio spectrum all the way from 1 MHz up to 6 GHz! Think of it like a FM radio where the frequency controls don’t stop at 88 MHz or 108 MHz and you could turn it way below or above that. That is exactly what a HackRF is!

You are definitely not limited to listening to radio stations though. You can basically receive all types of signals with the HackRF (depending on your antenna) including video and data signals which can be processed by your computer. In this guide I’m going to cover how to get started with a device like this in Ubuntu Linux and give you an idea of what kind of things you can do with it!
