RELEASE 7.0
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
- 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.
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
Typing SIGpi by itself will give you the list of commands available.
SIGpi includes it's own package management platform to update applications to their latest releases using familiar syntax from package management systems. Here is an overview of available commands.
Usage: SIGpi [ACTION] [TARGET] ACTION install install TARGET from current release remove remove installed TARGET purge remove installed TARGET and purge configs build compile and install TARGET (option may not be available) update check for update of TARGET upgrade upgrade TARGET to latest release TARGET A SIGpi package Usage: SIGpi [ACTION] ACTION SIGpi setup standard First time setup for desktop SIGpi setup server First time setup for server SIGpi list packages List all packages included with SIGpi SIGpi list installed List installed SIGpi packages SIGpi list library List all packages included with SIGpi with installed ones marked with an * SIGpi shell provide SIGpi env variables around a TARGET You can update packages in your existing SIGpi install. For example, Is there a SDRangel update. If so install it:
SIGpi update sdrangel Update 7.17.4 is available SIGpi upgrade sdrangel You can add/remove Packages anytime
SIGpi install audacity SIGpi remove audacity 
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)
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.
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.
