SDR# - Now with extensions

SDR# (read SDR Sharp) [Software Defined Radio] is a PC-based DSP application for Software Defined Radio. The code is mostly in C#, but can achieve reasonable performance. The main purpose is to offer a simple proof of concept application to get ones hands into DSP techniques.

Since initial development of my SDR radio (Digital Crystal Set) Youssef has made a complete rewrite. The current object model is engineered to allow extensions via plugins (Filters, Detectors/Demodulators, etc.), which is the main target. (Something like VST.)

SoftRock (Si570) Support has been added.

The source code can be found here: where you'll also find the latest runtime.

There's a newsgroup: Please join.

Thanks Youssef! 

How to run SDR#...

SDR# runs on Microsoft Windows with .NET Framework 2.0 installed. (If you need .NET Framework 2.0, Google for "Microsoft .NET Framework Version 2.0 Redistributable Package and install it.")

Download the SDR compressed file containing the program. Currently there's 3 DLLs and and one EXE. Copy them all to a folder, and run "SDRSharp.exe".

There's no other installation process.

Either download and play an SDR IQ WAV file, or use a Software Defined Radio connected to your PC sound card.

And my old favourite...


ensemble_rx_ii The Ensemble RX LF/HF kit and its 4.5" x 2" board represents the culmination of a long line of Softrock SDR receivers.
