SDR# (SDRSharp)

SDR# (read SDR Sharp) is a simple, intuitive, small and fast PC-based DSP application for Software Defined Radio. It’s written in C# with both object design correctness and performance in mind. The main purpose is to offer a simple proof of concept application to get hands into DSP techniques. Supported devices include:

  • AIRSpy
  • SoftRock
  • FiFiSDR
  • FUNcube Dongle
  • FUNcube Dongle Pro+
  • I/Q wav files
  • SDR-4
  • LazyDog’s LD-1
  • SDR-IQ
  • SDR-14
  • RTL2832U / RTLSDR (external)
  • Any sound card based SDR front end
  • Any ExtIO based SDR front end 1361 last supported version



There are some nice plugins that extend the features when using SDR# I will try to add and update this list with current version and new developments.


DDE/SDR# Satellite Tracking client:

An add-on to the excellent SDR# program which allows software to control the receive frequency in SDR# – required for best results to correct for the Doppler shift when working with satellites. It supports WXtrack, Orbitron and SatPC32. More information can be found at the following location from Satsignal.

Satellite Doppler control:

This plugin gives you the option to control doppler shift in combination with Orbitron satellite tracking software. As far as I now this is an experimental plugin and read the readme.txt file when you want the experiment with this plugin. I have got it running with SDR# version 1114 (download plugin)
