A rigorous, tradecraft-focused course for beginner to intermediate radio enthusiasts, covering fundamental RF theory, advanced toolchains (SDRPP, SDR-Trunk, SDRangel, Universal Radio Hacker), signal hunting, decoding, and replay with an emphasis on operational competence and ethical practices.
An aircraft monitor based on Charlie Gerard's JavaScript Aircraft Radar System. It requires an RTL-SDR USB dongle and a WebUSB capable browser.
This article details a DIY hydrogen-line radio telescope built from affordable materials like foam insulation board, a paint thinner can, an SDR (AirSpy), and amplifiers. It explains how to detect the 1420.4-MHz signal emitted by hydrogen to image the galaxy and measure galactic rotation.
GUI application for using HackRF as a spectrum analyzer with features like optimized settings, easy retuning, peak/persistent display, and more.
PySpecSDR is a Python-based Software Defined Radio (SDR) spectrum analyzer with real-time visualization, demodulation, and signal analysis capabilities.
The article discusses the issue of fake and cloned electronic devices and their impact on the original manufacturers, highlighting examples of spectrum analyzers and SDR boards. It raises questions about intellectual property, open-source projects, and the ethical implications of cloning and counterfeiting.
rtl_433 is an open-source program designed to decode radio transmissions from various devices operating on ISM bands. It supports RTL-SDR and SoapySDR and can decode a wide range of sensors, including temperature, humidity, and rain gauges. The software is written in C and is known for its low resource consumption.
Download 470 megapixel real-time images of Earth, captured every 10 minutes by the NOAA’s GOES-East satellite.
This article provides a guide on how to receive weather satellite images using SatDump.
Pi Pico Rx is a modern electronic project inspired by the crystal radio. It describes how Pi Pico Rx, using a Raspberry Pi Pico, an analogue switch, and an op-amp, can create a simple yet capable SDR receiver covering LW, MW, and SW bands, capable of receiving signals from around the globe. The project is still in the experimental stage, with more technical details available in the provided documentation.
