XRS - Extensible Radio Specification XRS Technology: Interfacing radio with computers.

To develop XRS client software (XRS plug-ins), you need the XRS Client Developer License. This license is free. A granted license will also enable you to get free access to the XRS Developers Resource Page, which greatly simplifies developing XRS plug-ins.

If you wish to develop XRS server software (i.e. software which controls a radio device on the lowest level) and make a particular radio device XRS-compliant as a result, then you will need to apply for a separate XRS OEM License. Such license would typically be applicable to radio manufacturers. This license is NOT free.

The XRS Client Developer License Agreement is provided in PDF format. If you don't have the Adobe Acrobat reader for PDF documents, we have provided a download link here for your convenience.

We will notify you of your official developer status by email, and, at the same time, give you access to the XRS Developers Resource Page. On this page you will find lots of useful information, including plug-in examples with source codes.


If you are a radio manufacturer, you should consider XRS because you can take advantage of XRS applications, existing and being developed. By making a radio device XRS-compatible, you will also make it automatically more useful to prospective purchasers, and more attractive to the market. Your strength is likely to be in hardware, so by tapping into the XRS development pool, you can worry less about software development.

The XRS OEM License allows you to develop XRS Servers, i.e. software which controls a radio device at the lowest level. An XRS Server makes a radio device XRS-compliant, which means that any XRS Client can be used with such device.

The XRS OEM License is subject to certain regulations and license fees. If you are interested in XRS OEM licensing please fill this form and click on the Submit button. We will be in touch with you shortly.
