System Requirements

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.

Not Supported

The following are not supported:

Only systems running Windows as the native operating system are supported. If the software runs with any of the above then you're a lucky camper!


Online Cluster

Here is a full DX cluster used by radio amateurs and shortwave listeners, just click on the image to display the cluster in a new browser window.


There are three main components:

  • Console, where you see and hear the signals,
  • Server, runs on a remote computer and 'servers' the remote SDR radios to the console,
  • Analyser where you create sonograms from long data recordings.



  • 6 receivers (VFOs)
  • SSB, CW, AM, FM, FM-Stereo
  • WASAPI & ASIO audio support


  • AGC
  • CW Peak Filter
  • Noise Blanker (NB)
  • Noise Reduction (NR)
  • Notch
  • Squelch


  • Audio Spectrum
  • Data Record / Playback
  • Favourites / Memories


The server manager is used to configure the software (a Windows service) on a remote computer, it is not required when using hardware connected to your own computer.

  • Up to ten simultaneous connections (one connection per radio),
  • Individual user accounts,
  • User-configurable TCP/IP port,
  • Updates optionally shown on ,
  • Full diagnostics.
