Introduction is an advanced Windows console for Software Defined Radio (SDR) receivers and transceivers. Designed for the commercial, government, amateur radio and short-wave listener communities, the software provides a powerful interface for all SDR users.

The software is being continually developed with new features added on a regular basis. Continuing the success of version 1.5, work on version 2 started in June 2012. As development proceeds this site will be updated. The official release date for version 2 is July 2013.

For more information you can read the documentation (from the Downloads page) and also watch the videos (one is available at the bottom of this page).


  • Clean user interface, no unnecessary features.
  • Client / server design - locate your SDR receiver anywhere in the world where's an internet connection, network bandwidth for acceptable reception can be as low as 45 kbps.
  • Low CPU usage, acheived by use of Intel's IPP library, highly efficient GDI+ programming and years of experience.
  • Licenced - to protect the codebase.
  • Multi-monitor support.
