M1KTA's QRP ham radio blog Other than a trip which might get the odd mention I will detail projects I am working on, what I want to be working on and what I have otherwise to report on. Dial Tone Example Posted on June 26, 2013 by chaudhryosama The simplest example is the dial_tone example in which you will be listening a dial tone from the sound card. Note that Amplitude is only real while Offset can be complex. I want to make a simple FM receiver, comparable to what was done via rtl_fm in RTL-SDR - Software Defined Radio (SDR) for $20. GNU Radio is a software development toolkit that provides signal processing blocks to implement software radios. It should work with any device that works with that block, including Realtek RTL2832U devices. Through a few small tweaks to an existing program, we can start to add QT sinks to the flow graph to start to visualize different signals, which can be especially useful when debugging and analyzing signals. edu Oregon Institute of Technology Back to My collection of GNU radio companion flow graphs Back to Aaron's home page. Data le for rst case study. GNU Radio provides a couple of GUI interfaces using wxPython or QT. org •Open source software radio •Provides the scheduler for real-time operation •Includes: -Many signal processing blocks -Interfaces to a few radio front ends -Graphical user interfaces (GUI) -Examples •A platform to build and explore radios (or any other communications platform). Signal sink is where the signal is translated into the form that user desired.
