Time to give an update! Read more... New Set of Beginner Level TutorialsGNU Radio doesn't have a notion of sampling rate itself. The term sampling rate is only used by certain blocks to e.g. calculate the period of a sine (in the case of the signal source: Period = f_signal/f_sample), or to calculate times or frequencies that are written on display axes (like in your case).Then, GNU Radio 3.9.2.0 (and later) comes with gr-soapy built in - that means all the SDR hardware for which a SoapySDR plugin exists can be used without needing any third-party GNU Radio module ...Using GNU Radio Companion: Tutorial 1 GNU Radio Companion (GRC) is a graphical user interface that allows you to build GNU Radio flow graphs. It is an excellent way to learn the basics of GNU Radio. This is the first in a series of tutorials that will introduce you to the use of GRC. 1.PyRadio is a convenient, open source, command-line application for playing any radio station that has a streaming link. And in 2019, almost every radio station (certainly, every one that has a web presence) has a way to listen online. Using the free PyRadio program, you can add, edit, play and switch between your own selected list of streaming radio stations.GNU Radio Companion. The gr-lte project aims to provide a modular environment for an LTE downlink receiver, achieving this by providing signal processing blocks within the GNU Radio framework and its accompanying IDE, GNU Radio Companion. Although gr-lte is published under an open source licence it looks as though MATLAB may be a software ...In the Wav file source we have to choose the input file source where we store our audio file. 2. Figure-5 shows the graph for our Wav file before the WBFM block. Figure 5. Original Wav file signal 3. Then this input file is sent the WBFM block where audio rate is predefined.GNU Radio for Windows. GNU Radio is a powerful Software Defined Radio (SDR) tool for Linux systems. However, if you are a daily Windows user and want to play with SDR, building it on Windows is a huge challenge, even in Linux. There are lot of dependencies that are specific for Linux and it is not an easy task to port to Windows. 4. Run GNU Radio Double click the GNU Radio icon on your desktop.
