It is particularly suitable for standard DIFAR sonobuoys operating in the 136 to 173.5 MHz standard sonobouoy VHF band. This standard frequency range can be extended to UHF frequencies (up to 1.8 GHz) to suit customized telemetry requirements.

The WR-G39WSBi features an antenna input, analog output, as well as digitized audio output via the PCI bus for spectrum analysis and monitoring.

The fully self-contained receiver resides on a standard PCI-bus card designed to be installed in a standard or industrial-grade PC. The receiver is supplied together with Windows control software (Linux support is optional) and support documentation.

The receiver's modular architecture allows for a high-degree of customization for application-specific requirements. The receiver also contains its own DSP, making it possible to develop customized solutions featuring various on-board signal processing, analysis and decoding facilities.

As most of the RF signal processing is performed by the card, the PC hardware and software requirements are modest. Up to eight cards can be plugged into the same computer, and controlled separately and independently. WiNRADiO can also supply complete rack-mounted multi-channel systems.
