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.)

Excel formulas to calculate IP values - Works in Excel and Google Sheet.

Updated 2023-12-11: Hosts calculation updated to support CIDR or 31 and 32.

Prerequisites:

  • A1 contains an IP address, such as 10.0.0.2
  • B1 contains the number of bits in the netmask (CIDR) such as 24

The below formulas then go into C1, D1 etc. to perform the various calculations. Some calculations depends on other calculations.
