foreword: SDRNode is the streaming component of the Cloud-SDR suite. It is a commercial software used to share local SDR devices to remote clients (like cSDRc the Cloud-SDR client). 

You can download an evaluation version of SDRNode, you will be able to use it for 30 days. After that trial period, you must purchase a valid license to continue enjoying SDR remote access.



For more details on what is the Cloud-SDR concept, please check this page.

Frequency coverage

Please note Cloud-SDR is an amateur product and has frequency coverage restrictions.

  • The evaluation version is limited to the range 0 – 1000 MHz,
  • The other versions prevent the SDR receivers to tune outside the following bands:
    • 0 to 1300 Mhz,
    • 2300 to 2450 Mhz,
    • 3.3 to 3.5 GHz,
    • 5.650 to 5.925 GHz,
    • 10.000 to 10.500 GHz,
    • 24.000 to 24.250 GHz.

This coverage can be updated on request – contact us.

Supported hardware

The following SDR receivers drivers are currently available:

  1. RTLSDR,
  2. AirSpy (1; R2 and Mini)
  3. BladeRF (x40 and x120);
  4. SDRPlay (1 and 2);
  5. PerseusSDR.

The different drivers for local hardware are open-source and available on our Github repository.


Like other Cloud-SDR software, support is provided through the community forum:

SDR receivers configuration

For the SDRPlay receivers, you must install the drivers published from the company website ( :


make sure you select the API/HARDWARE DRIVER 2.09. If you already have installed a previous version of the drivers, you have to update your setup because of important changes that make the older drivers not compatible with current version of the SDRPlay driver.

For other receivers (RTLSDR, AirSpy, BladeRF, …) you need to use ZADIG Usb configurator as follows:

  1. Plug your hardware device in your PC
  2. Start Zadig
  3. Search for the device in the combo box
  4. Install/replace driver with WinUSB (libusb)


When your SDR hardware is correctly configured, it should appear – when connected – under the “Universal Serial Bus devices” item in the Device Manager, as shown in the following :


Getting the SDRNode software

You will find the download packages from the “my account” sections of our store.

Installing SDRNode

When you start the installation program, it asks to enter the Activation key that was obtained after successful checkout on our store:


Type your activation key and press Next.

During the installation procedure, a Windows Service will be installed. This requires privileged access, so the installer will ask you to accept to run in “admin” mode:


Once you have clicked Yes, the installation procedure continues and you are requested to accept the License Agreement:


Click Next. You now have to select the destination folder for the program.


You can keep the proposed folder. After clicking Next, you will have to select what is your installation type :


You have to decide if you want to include the open source drivers or not.  Note that by default they are selected. Click Next. The installation continues up to this last page :


Choose the “Installs SDRNode service” to have automatic configuration and activation of your SDRNode software. Once this last action has been performed, you receive a confirmation email saying your license has been activated:


Going back to your account page shows that this license is now used.

The installation program configures your machine for automatic startup of the SDRNode software after reboot. You can check this by opening the “Computer Management Console” .



Once you have checked the correct installation, it is strongly recommended you reboot your computer before using SDRNode streaming server.
