SDR# Sharp Ubuntu

Build SDR-sharp

This procedure was tested with Ubuntu 16.04 and MonoDevelop 5.10 on a 64-bit Intel laptop with the ubiquitous $20 RTL-SDR USB stick receiver.

  1. Install SDR# prereqs

    apt install mono-complete libportaudio2 librtlsdr0
  2. Build SDR#.

    git clone
    cd sdrsharp
    xbuild /p:TargetFrameworkVersion="v4.5" /p:Configuration=Release
  3. Softlinks help your Mono executable find the audio libraries.

    cd Release
    ln -s /usr/lib/x86_64-linux-gnu/
    ln -s /usr/lib/x86_64-linux-gnu/ librtlsdr.dll


In Linux,

mono SDRSharp.exe

Set audio buffer to 200ms, sample rate to 2.048Mbps


Find library paths

In general you can find the path(s) to a Linux library by:

dpkg -L libportaudio2
