Rtl-sdr

ViewRF software – RTL-SDR Spectrum Analyzer for BeagleBone Black. JNX. Figure 1: JNX text display Figure 2: JNX time and spectrum display Introduction First, to avoid confusion, I have another program named JWX that receives shortwave signals from a computer's sound card and creates graphic weather charts.

It's closely related, but not the same. This program, JNX, receives shortwave radio signals from a computer's sound card and creates Navtex weather reports in text form. Installation This program is released under the GPL. Operation If the explanations in this section either make no sense or seem too elementary, please read the technical description farther down the page. Technical Section This section provides an in-depth look at Navtex, how JNX detects and processes it, and the digital signal-processing methods used in JNX.

The Navtex system is designed to be an automated, medium-range, meteorological and nautical data dissemination scheme. WXtoImg: software to decode APT and WEFAX signals from weather satellites. Thema anzeigen - Diskussion über das RTL-SDR. Hallo Da mittlerweile diverse User ein SDR benutzen, wollte ich hier nun mal einige Empfänger untereinander vergleichen.

Es treten folgende Kandidaten an: Hama nano DVB-TNoxon DAB / DAB+ (revision 2)Funcube Dongle (the original) Mit dem Programm rtl_test kann man die Eckdaten seines RTL-SDR auslesen. Wie man das Programm installiert, erfährst du hier: Windows Software [rtlsdr.org wiki] Until recently the only quick and easy option for using RTLSDR was with WINSDR and HDSDR with the EXTIO plugin from spench.net.

This has all changed now and all you need is the very nice, fast and open source SDR#. It natively supports RTLSDR hardware (along with FUNCUBE and the audio card) and is much kinder on the CPU than the others. Zadig · pbatard/libwdi Wiki. Zadig 2.0 - User Guide Basic usage In its simplest mode of operation, Zadig is meant to install a libusbx compatible driver, for a device that does not yet have such a driver installed.

Below is an overview for a typical driver installation: On Windows Vista or later, the first screen you will see when launching Zadig is the User Account Control prompt displayed below. This is because the application needs to run with administrative privileges. Advanced usage For power users, Zadig offers the following list of features: Advanced Mode (Options → Advanced Mode):In this mode, additional information is displayed, and users also have the ability to select the directory where the files should be extracted.Setting of the options through an INI file:All the options that can be set in the menus can also be set from a zadig.ini file, which Zadig attempts to read when started. Example of a zadig.ini file.

Tutorial: Receiving Airplane Data with ACARS. What is ACARS?

ACARS is an acronym for Aircraft Communications Addressing and Reporting System which is a digital communications system that aircraft use to send and receive short messages to and from ground stations. Standard ACARS transmits at a frequency of 131.550MHz, which is squarely in the receivable range of the RTL-SDR. The RTL-SDR software radio can be used as a radio scanner for listening to these digital messages, and with the help of some decoding software, can be used to decode and display the messages. The messages you can receive will be from nearby aircraft and ground stations. Most messages will be unreadable data intended for computers, but you can find out what is flying near you by decoding the flight number and aircraft registration details sent with every message. Tutorial: Cheap AIS Ship Tracking. Large ships and passenger boats are required to broadcast an identification signal containing position, course, speed, destination, and vessel dimension information to help prevent sea collisions.

This system is known as the “Automatic Identification System” or AIS for short. There are dedicated AIS receivers intended to be used on boats, or by hobbyists, but they can be expensive. A radio scanner or the cheap rtl-sdr can be used to receive these signals, and with the help of decoding software, ship positions can be plotted on a map. Tutorial: Receiving NOAA Weather Satellite Images. Everyday multiple NOAA weather satellites pass above you.

Each NOAA weather satellite broadcasts an Automatic Picture Transmission (APT) signal, which contains a live weather image of your area. The rtl-sdr dongle combined with a good antenna, SDRSharp and a decoding program can be used to download and display these live images several times a day. This tutorial will show you how to set up a NOAA weather satellite receiving station, which will allow you to gather several live weather satellite images each day. Most parts of this tutorial are also applicable to other software radios, such as the funcube dongle and HackRF, but the rtl-sdr is the cheapest option. Hardware radio scanners can also work, provided the radio has a large IF bandwidth (30 KHz +) and a discriminator tap.

Examples. Tutorial: Decoding DRM Radio. Digital Radio Monodial (DRM) radio is a type of digital shortwave radio signal that is used by international shortwave radio broadcasters.

It provides superior audio quality compared to AM signals by using digital audio encoding. A Software Defined Radio in C# List of SDRSharp Plugins.
