The task of multichannel radio frequency surveillance and monitoring would typically involve a number of separate radio receivers, audio recorders and other discrete components interconnected into bulky and expensive systems.

The WiNRADiO MS-8118/G3 Multichannel Monitoring System provides an elegant, fully integrated solution, specifically designed for computer-controlled automatic monitoring of frequencies ranging from VLF frequencies up to low microwave, in all major modulation modes. The system is designed to monitor radio frequencies on multiple channels simultaneously, record digitized signals on the hard disk for easy later retrieval, and perform automatic decisions based on the received signals.

This system is based on a ruggedized heavy-duty 19” rackmounted industrial computer. The front panel features a high-contrast wide-angle display. There is provision for connection of an external keyboard and mouse. The system is capable of simultaneous independent monitoring of up to eight channels from VLF to SHF frequencies

The built-in hard disk allows a typical storage of several months of continuous recording, and a re-writable CD-ROM or DVD drive makes archiving of recordings easy. The unit is capable of unattended operation and, if the Client/Server Option is fitted, it can be operated remotely via a standard TCP/IP connection such as LAN or the Internet. The recorded audio can also be remotely searched and streamed to the operator.

Receivers

WiNRADiO software-defined receivers are at the heart of the the MS-8118/G3 Multichannel Radio Monitoring Systems, making it possible to achieve the necessary high level of integration and performance.

Frequencies from 9 kHz up to 8.6 GHz can be monitored and logged. The receivers offers an unparalleled flexibility given their software-defined architecture, excellent dynamic range, and high sensitivity. Many useful features complement the receivers, making them capable of filling not only the role of a search and monitoring receiver but also that of a measuring receiver, such as the calibrated S-meter showing the received signal levels in dBm, µV or S-units, down to the -140 dBm noise floor, several spectrum analyzers, and many other features.

The MS-8118/G3 Multichannel Radio Monitoring System can be custom-fitted with a combination of receivers for different frequency ranges and capabilities, to optimize the system for a specific application and to maintain a minimum cost.

 
User interface

The MS-8118/G3 Multichannel Radio Monitoring System makes it possible for the user to control each individual receiver separately and observe its operational status, as well as set the system parameters for multichannel monitoring and surveillance operations.

Each receiver can operate totally indepedently, as a high-performance scanner with additional advanced facilities for automated task scheduling, spectrum analysis, signal strength logging, channel occupancy analysis, programmable audio recording, and many other features. Alternatively, the receivers can work in "master/slave" roles, where a "master" search receiver hands off its found frequency to a "slave" for monitoring, while continuing search.

The informative graphical user interface of the MS-8118/G3 system makes it possible for the user to observe the status of the individual receiver channels at a glance, and set-up monitoring tasks for a wide range of applications ranging from conventional logging and time-schedule recording, to sophisticated, fully automated, remotely-controlled radio surveillance operations.

The MS-8118-CSO Client/Server optional software makes it possible to operate the system remotely via a computer network or a dial-up telephone connection. The software provides a TCP/IP control path for the receivers and streaming audio feedback in real-time.

The software also allows the Client (the local computer) to initiate audio recording to the Server's hard disk. Associated functions allow the Client to search and stream the stored audio files over the network.

A variety of sampling rates and compression algorithms are supported, for optimum sound quality and storage space.

The MS-8118/G3 Multichannel Radio Monitoring System is shipped in a specially designed ruggedized 19" rack-mounted chassis with built-in shock absorbers, to ensure safe shipping.

The unit can then be either removed from the enclosure, or operated from inside it. This is particularly useful for mobile operation.

For stationary applications, various rack-mount options are also available, ranging from a single-unit arrangements (pictured) to large-scale installations. For these, WiNRADiO provides complete turn-key solutions including antennas and antenna distribution units.
