Sharing your receiver

GlobalTuners allows you to share your radio receiver with other radio enthusiasts. Sharing your receiver is fun and grants you immediate access to the Premium membership features. The GlobalTuners software, which is developed specifically for GlobalTuners and is owned by us, is easy to setup and requires little maintenance. Our user database allows us to easily deal with abuse. We are always open to suggestions and experiments which may improve the website and software.


Before you begin, please make sure you have the necessary equipment to share a receiver. The following sections will give some information about the required hardware.


The GlobalTuners URadioServer software can run on almost any computer, including embedded platforms like the Raspberry Pi. We recommend at least an 1GHz processor, 256MB RAM and 2GB of free harddisk space.

For SDR receivers, we recommend to use a computer with an Intel Core2-series or i-series processor or similar AMD processor.

The computer system must also have appropriate connections for the receiver's control and audio connections. Most receivers require a 9-pin RS232 serial port and a soundcard with line-in connection. Some receivers (RTL2832-SDR, ICOM PCR-1500) need only a single USB connection. Please make sure you have the necessary cabling to connect the receiver to the computer.

Supported receivers

We support a wide variety of receivers. You can find the complete list in the registration form.

  • Icom PCR-100, PCR-1000, PCR-1500
  • Most other Icom transceivers and receivers with a RS232 or CI-V serial interface (IC-706, R8000, etc)
  • AOR AR-7030, AR-8020, AR-8600
  • JRC NRD525, NRD545
  • Yaesu FT-817, VR5000, FRG-9600, ...
  • RTL2832 and other SDR receivers supported by the SDRSharp (SDR#) software

Internet connection

The GlobalTuners RadioServer software works with almost any commonly available internet connection. We have technologies in place to minimize bandwidth usage and to work around firewalls without special configuration.


If this is the first time you share this receiver, you have to register it by filling out the Share your receiver form. Upon completion of the form you can continue to the software installation.

Software installation

The GlobalTuners RadioServer software can be installed on most modern operating systems. It is recommended to use a dedicated computer for the GlobalTuners server, but it is possible to run the software on a workstation as well. Our team can support you in installing the operating system and server software. Please close any other software that may take control of the receiver at least until the receiver has been activated by our team.

Installation as an SDRSharp plugin

You can install the GlobalTuners RadioServer as an SDRSharp plugin. This will allow the RadioServer software to take control of SDRSharp and its high quality SDR algorithms, while you can still watch the spectrum display and listen to the local audio output. We have tested the software with SDRSharp versions and Other versions may or may not work.

  1. Download the plugin for verion or download the plugin for version and extract the contents to your SDR# installation directory. Choose to overwrite Plugins.xml when asked (or manually add the plugin registration to your local configuration file).
  2. Start SDR#.
  3. Click Associate GlobalTuners node in the GlobalTuners URadioServer plugin panel and complete the wizard.
  4. You can now mute the audio in SDR#. Audio will still be sent to GlobalTuners.


When the software is installed correctly, you will receive an automatically generated e-mail informing you that the software has been installed. An administrator will soon complete the configuration and activate the receiver. Please make sure the computer and the software remain online until it is activated (this may take several days), or send us an e-mail informing when the system will be online if you can't keep it running 24/7.

Once the receiver is activated, your account will be upgraded to the Site operator level. This will allow you to access the administrative functions for your own receiver and includes the Premium membership benefits. You may continue reading Your receiver is online, now what? to find out how to use the administrative functions to make your receiver more interesting for others to use.
