The WiNRADiO RLX-800 Network Receiver consists of a software-defined radio receiver and a web server on a Linux-based industrial computer platform.

No additional hardware such as a PC, keyboard or monitor are required on the server side. The unit contains a highly reliable fanless Linux computer for server-side processing and storage. The actual receivers are well proven WR-G313i (9 kHz to 30 or 180 MHz) or WR-G315i (9 kHz to 1.8 GHz) models. Simply plug the unit to a LAN or Internet network via a standard RJ-45 connector, and it is ready to be used.

The web-based configuration interface makes it possible to fully configure the communication parameters, such as the IP address, ports, users, passwords and user access rights.

Each user can be assigned different access rights, which may include the rights to control the receiver, retrieve saved information, etc.

Both audio and IF recording and playback are possible. As monitoring activities take place in the server, this makes it possible to start a monitoring task remotely and then disconnect the client. The task then keeps running autonomously. A typical task may include recording, spectrum sweeping or activity monitoring. The results can be saved on the server and later downloaded for later processing and analysis. Web-based user control makes it possible to create separate user accounts.

Recorded files are saved on the server and can be organized in folders. The client-side Java applet includes a file manager that makes it possible to organize and view recorded files.

Apart from a standard web browser, the RLX-800 Network Receiver does not require any additional application software on the client side; all is provided by the built-in Java applet which runs on most common platforms. The Java applet makes it possible to observe the signal spectrum, measure the signal strength, tune the receiver, set the demodulation mode, control the IF filter bandwidth and other parameters such as volume, notch or audio filter, and listen to or record the demodulated audio.
