SDR# Download

SDR# (SDRSharp) is a popular, simple, fast and extensible Software Defined Radio program written from scratch in C# to experiment new Digital Signal Processing techniques and push the Microsoft .NET Framework to its limits.

We release new versions very often so we invite you to visit this page frequently for updates.

This software is brought to you free of charge, but if you like it, consider purchasing our hardware.

SDR# Plugins

SDR# has a modular architecture that allows adding new functionality with the mean of "plugins". This page lists the default plugins that come with the software package and a few recommended third party plugins.

If you are a programmer and want to develop your own, you may have a look on the developer package.
