SDRTrunk Cheatsheet / Quick start guide

SDRTrunk Quick Start Guide

Things you're going to need:

  • HackRF / 1-3+ RTL-SDR(s) depending on system bandwidth
  • ARM (Ubuntu/Linux/Raspberry Pi OS on RPi, or Kali Nethunter on OnePlus 8 Pro or similar), or x86 compute platform. Preferably with 12GB-16GB+ of ram; but 8GB should work for some applications.
  • Suitable antennas. My local area uses ~770MHz.
  • Radio Reference subscription (techincally optional, but highly recommended. they run a great service.)
