SDR – ADS-B Decoding: dump1090 (Linux/OSX)

Previously, I covered RTL1090 to observe ADS-B signals on the Microsoft Windows Operating System. In this post post I will walk you through the simple operation of the Linux & OSX equivalent dump1090.  This Open-Source package performs just as good as its Windows counterpart, maybe even better as no additional mapping software is necessary. Source Code git clone https://github.com/antirez/dump1090.git

SDR – ADS-B Decoding: RTL1090 (Windows)

RTL1090 is  a program that will automatically decode ADS-B signals that are commonly found on the 1090MHz frequency.  Alternatively known as Mode S, ADS-B allows a variety of types of data to be sent from the transponder, including: ICAO aircraft code (the tail number of the plane can be obtained from this) Flight Number Altitude Location (Longitude and Latitude) Heading Using this software on Windows from the picture above we can…

SDR: Ham It Up!

I want to bring your attention to the Ham It up v2.1 a high-quality RF (MF, HF) converter for Software Defined Radio (SDR) devices like the RTL-SDR DVB units and the Funcube dongle.  I personally believe its the best SDR upconverter currently available.  They’ve  even added a noise source circuit; However, you need to source a few extra components to complete the circuit. Why use an up-convertor? The RTL2383 + Elonics E4000-based DVB-T tuner…

Gnuradio – OSX Installation Guide

I briefly mentioned previously about using gnu radio on Linux or OSX.  Today I will walkthough the installation process on OSX. First install MacPorts if you have not already done so: http://www.macports.org. First install the rtl-sdr drivers: port install gr-osmosdr Now the latest version of gnuradio uses variants: port info gnuradio Password: gnuradio @3.7.1 (science, comms) Sub-ports: gnuradio-devel, gnuradio-next Variants: debug, docs, full, grc, jack, orc, portaudio, python26, [+]python27, qtgui, sdl, swig,…

SDR : Software Defined Radio

Recently, I’ve been busy playing with Software Defined Radio (SDR).  I was able to get my hands on one of these cheap TV dongles with the Realtek 2832U Chipset.  So what’s the big deal? A V4L/DVB kernel developer  Antti Palosaar, discovered that the chip allows transferring the raw I/Q samples to the host, which is officially used for DAB/DAB+/FM demodulation.The RTL2832U outputs 8-bit I/Q-samples, and the highest theoretically possible sample-rate is…
