SIGpi

RELEASE 7.0

Introduction

SIGpi is a "go-kit" for Signal Intelligence (SIGINT) enthusiasts with capabilities in the HF, VHF, UHF, and SHF spectrum. It includes a framework for simple installation and management of popular SIGINT appliucations and devices made mostly from bash scripts building/installing SIGINT tools on the following platforms:

• Raspberry Pi4 4GB RAM or Raspberry Pi 400 with 32GB microSD card running Raspberry Pi OS "Bullseye" or "Bookworm" Full (64-bit)
• arm64 or amd64 platforms with 4GB RAM and 32GB storage minimum runniing Ubuntu 22.04 LTS

Quick Setup

• Login as pi or sudo user on supported platform
• Update and install pre-requisite packages to install SIGpi
• From your home directory, create a directory called SIG and switch into it
• Clone the SIGpi repo
• Change directory into SIGpi

sudo apt update && sudo apt upgrade
sudo apt-get install -y build-essential cmake git
cd ~
mkdir ~/SIG && cd ~/SIG
git clone https://github.com/joecupano/SIGpi.git
cd SIGpi

Run the following command from $HOME/SIG/SIGpi to install the framework and package management

./SIGpi setup standard

After setup system will reboot.

Add a Package

Once setup, you can list the inventory of packages SIGpi includes as well as those already installed with the following command (note that ./ is no longer required for thr SIGpi command after setup)

SIGpi list library

An asterisk in the INSTALLED column indicates that package is already installed while those withou asterisks have not been installed. For example, you will see SDRangel has not been installed. You can do so with the following command.

SIGpi install sdrangel

Go back and list again to install other packages of interest

Example Hardware Setup

Power

In this setup a 12V@17A switching supply powers all the kit. Since RPi4 are picky about getting 5.1V a set-up converter is added to power it. A 12V Rpi4 are pickya bout getting 5.1V. USB peripherals can be hungry so a powered USB hub is included. While 7 ports are available no more than three devices requiring power should be enabled since hub produces a maximum of 36 Watts ( 3 x 5V x 2.4A = 36 Watts)

Raspberry RPi4

Since this is a SIGINT platform we do not want to be generating any RF so onboard Bluetooth and WiFi should be disabled. If Internet is needed and only available via WiFi then so be it and use your onboard WiFi.

USB Peripherals

Only three USB devices requiring power should be enabled at a time. The range of devices depicted is only to demonstrate what you could potentially connect to it.
