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?


The current stable release is version 2. Development effort is now concentrated on version 3, for full information about this exciting new project click here. 



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!


What is a SDR receiver?

Software-defined radio (SDR) is a radio communication system where components that have been typically implemented in hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a personal computer or embedded system.

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.)


Commercial and government users must either purchase a licence from TSS Inc. or have written permission from The commercial version of this software is compiled from a secure codebase, supported 365 x 24 x 7 by a team of SIGINT professionals and in use in hostile and very challenging environments.

  • Support: 365 x 24 x 7
  • Guarantee: yes
  • Future-proof: yes
  • Software expires: no
  • Training available: on-site anywhere
  • Source available: via escrow in a working Windows Hyper-V environment



20 MHz HF: How HackRF One performs on shortwave

©2016, Nils Schiffhauer, DK8OK

The world is full of software-defined radio (SDR), but HackRF One has a rather unique position – thanks to its vast maximum bandwidth of 20 MHz. With an up-converter, this combination covers more than 70 percent of the whole HF range from 3 to 30 MHz. Even better: with proper software you can record and play this enormous band!

However, this stunning bandwidth is achieved by a moderate resolution of 8 bit, resulting in a dynamic range of just nearly 50 dB. Or the half of SDRs like Elad’s FDM-S2.

Anyway. I wanted to know in practice what you can actually do with such a set at a budget price plus mostly free software. The results surprised even me: Properly used, this combination convinced as a quite decent performer on HF! The world map above shows some of the stations received with the set (see insert bottom left) to test its performance.



The console has a full satellite tracking module which provides correct Doppler correction of any satellite.

Frequency Manager Suite

June 27th, 2016 Jeff Knapp writes:

I now have a version of the Frequency Manager Suite for use with SDR Console v2.3. This is a subset of FMSuite for SDR#; it includes the Frequency Manager plugin (but not the Scanner), the Frequency Data Display plugin, the Scheduler plugin, and the Data Tools Wizard. It runs in its own window separately from SDR Console. These are the same software, and use the same database, as the SDR# version so you can share databases between the two applications.

Because SDR Console v2.3 was never intended for this purpose its only communications with other applications is through a virtual serial port. This communication channel can be slow, which makes scanning impractical. So this release does not include a scanner or related plugins.

But you can still send and receive frequencies with SDR Console and enjoy the other advanced features of the Frequency Manager and the Scheduler, and the Data Tools Wizard's ability to import and export radio station databases.

As development of SDR Console v3 proceeds I hope to add complete functionality to this version of FMSuite. Download the SDR Console v2.3 version from Frequency Manager Suite; and I hope you enjoy it.

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.
