SIGpi: A Signal Intelligence Focused Linux “Go-Kit”

Thank you to Joe NE2Z for sharing his Linux distribution called SIGpi. SIGpi is an installable Linux distribution for Ubuntu and Raspberry Pi 3/4 that focuses on providing multiple open source SDR programs that can be used for signal intelligence. Support for RTL-SDR and other SDRs is included.

The distro is actually created via a bash script that installs all the programs automatically on a fresh OS install. It also provides a system for easily upgrading software as developers work on them.

For a full list of the software that comes with SIGpi check out their Wiki.

SIGpi is a "go-kit" for Signal Intelligence (SIGINT) enthusiasts with emphasis on capabilities in the VHF, UHF, and SHF spectrum. For completeness, HF spectrum related software is included for optional install. This (bash) shell script builds SIGINT tools on the following platforms:

  • Raspberry Pi4 4GB RAM or Raspberry Pi 400 with 32GB microSD card running Raspberry Pi OS Full (64-bit)
  • Ubuntu 22.04 LTS on arm64 and amd64

A headless server only install (Node Install) can be performed on Raspberry Pi3 B+ with 32GB microSD card running Raspberry Pi OS Full (64-bit)
