CloudSDR prototype, radio from RFspace, coming soon!
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. GmbH is working very closely with RFspace Inc. of Atlanta, Georgia, USA 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 the radios from RFspace: CloudSDR, SDR-IQ, SDR-14, SDR-IP and the NetSDR. Soundcard radios such as SoftRocks are also supported, as are many more such as the excellent FUNcube Dongle. What are you waiting for?

  • 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.

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
