WiNRADiO G313 Series Software Developer's Information

Software Developer's Kit

The SDK document outlines the API specification for the G313 series of WiNRADiO receivers, including the interfacing syntax and examples for C/C++, C# and Delphi programming languages.

This makes it possible for a third-party software developer to gain complete control over the G313 receiver. This includes tuning the receiver, controlling the attenuator and gain, changing demodulation mode, IF bandwidth, volume as well as reading the signal strength.

The IF signal can be also obtained via the API, already conveniently digitized, ready for processing by the developer's own software.

The API can be used by any 32-bit application under Microsoft Windows 2000, XP, Vista, Windows 7, Windows 8 and Windows 10 (including their 64-bit versions).

The WRG3130API.DLL API file is available as standard part of the WiNRADiO G313 application installer which is supplied with the receiver and can be also downloaded here. A C/C++ header file g313api.h is also available.


Memory File Format

The WiNRADiO G313 series uses a specialized file format. The format is provided here for the benefit of our users and third-party developers.

 DOWNLOAD Memory File Format

Please note that non-adherence to the specified format may yield unexpected results when attempting to load memory files created by non-complying third party software. However, while such a mismatch may cause undesired operation, it can't damage the receiver.
