Introduction is a 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. is working very closely with major hardware manufacturers to bring you the best SDR experience available today.

The software is being continually developed with new features added on a regular basis. Licenced radio amateurs and shortwave listeners do not need a licence to use this software.

This software supports radio from most major manufacturers, simple soundcard radios such as SoftRocks and the excellent FUNcube Dongles. What are you waiting for?

Key Features (V2)

  • 6 receivers (VFOs)
  • SSB, CW, AM, FM, FM-Stereo
  • WASAPI & ASIO audio support
  • Recording and playback of base (IQ) data
  • Digital mode display (PSK, RTTY)
  • User-selectable colour palette
  • Spectrum scale in dBm, dBµV and S-Units
  • Unlimited Favourites
  • Quick memories
  • Supports Windows XP through to the latest version Windows 10 although Windows XP is not encouraged.
  • 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.

    Computer Talk

    This software is designed for Windows on the x86 hardware only, Windows on the Raspberry Pi is not supported. Although the software runs on Core 2 Duo systems with 32-bit Windows XP, the recommended minimum system configuration for a new hardware acquisition is:

    • Windows 7 64-bit,
    • Intel I3,
    • 8GB RAM.

    If you are buying a video card (GPU) then NVIDIA is recommended as the software makes use of the CUDA interface for CPU-intensive computation if such a card is available. Other manufacturers may be supported at a later date.

    To ensure support for SDR solutions coming to market over the next few years at least a third-generation CPU such as i5-3570 or i7-3770 should be used as these new SDR receivers will offer bandwidths of 20MHz or more which in turn require significant processing power and internal bandwidth. 

    Newer computers generally use less power; have better processing and often a lower footprint.

    Licencing & Legal


    This software is available free of charge only for hobby users such as  radio amateurs and shortwave enthusiasts. (The development is funded by the commercial licencees.)

    HF Radio Integration

    Of course you can integrate an HF transceiver with an SDR receiver to create the ultimate solution in terms of cost effectiveness, integration and system flexibility.

    By using a standard transceiver you have the advantage of a 'real radio', by adding an SDR receiver you have not only the ultimate bandscope but also a receiver which out-performs almost any other receiver! 

    You can buy an SDR receiver such as the SDR-IQ from RFspace plus a PC bundle from your local store for less than the cost of most external bandscopes.
