SDR receivers like the SDRPlay or the Airspy cover a very wide frequency range, and most of the time one single antenna is not suitable to cover the different spectrum portions. SDRNode offers a way to remotely receive the IQ radio stream but – when multiple antennas are needed – a way to switch from …
Extracting the sub-band of interest from a wide-band SDR device is a classical signal processing task and is the core of what SDRNode software is doing. This channelization process is exactly what your favorite SDR console program is doing: extract a tight band and demodulate it before sending it to your loudspeaker. There are several …
SDRNode server has an embedded Web server for basic configuration for the users to do not want to go through the use of scripting system. By default, the configuration wizard can only be accessed from the server itself (local). The configuration pages are available browsing to http://localhost:8080/ (unless different TCP/IP configuration, check wiki here). In …
Cloud-SDR SDRNode software includes specific drivers for each supported device. Of course, these drivers are based on authors or manufacturer code examples or libraries. To stay fully compliant with the different flavors of licenses used by the different equipment, we have decided to change slightly the way SDR are managed and we generalized the mechanism …
SDRNode can now be easily extended to new hardware by using the Open Source driver framework. As an example and to stay compliant with the GPL License used with the RTLSDR dongles, we have published an example driver on Github https://github.com/f4gkr/Cloud-SDR-RTLSDR This is still a beta version, enhancements are ongoing for a better identification of …
Several testers reported that using scripting for configuration was not the easiest way to start with SDRNode. To simplify the setup, we have added a complete user-friendly web front-end to configure the software. This secured new module is the easiest way to configure and share your SDR devices in a few mouse clicks ! This …
Abstract SDRNode can do IQ streaming but has also scripting capabilities to run in ‘standalone’ mode and do some Digital Signal Processing in the background. In this tutorial we will explore these capabilities and show how to add a script that scans HF bands to monitor activity and relay the information to users. In this …
