Finally got it working smoothly… The Odroid XU4 from Hardkernel is a great small multicore Linux ARM Machine for the price ! Our SDRNode SDR streaming server now compiles and runs smoothly on Odroid. Update: We are considering to offer for sale pre-installed images of SDRNode on Odroid and maybe ready-to-use Odroid boards with casing etc. …

Feed openWebRX from remote SDRNode stream
A new command line tool called remotestream is now available offering many features: retune remote stream, download stream and save to wav file, download stream and write to output. This last feature – specially under linux – makes it possible to pipe IQ stream coming from remote SDRNode to another application, like OpenWebRX for example. …
Experimental EXTIO available for testing
EXTIO is a Windows DLL (shared library) originally developped for Winrad, extended by HDSDR developers and now a kind of standard to connect new type of SDR. This Cloud-SDR EXTIO is a way to “trick” your local software (HDSDR or SDRUno for example) and make it think the remote device is locally connected to the …
Optimizing SDR performances on multi core processors: introducing the Cloud-SDR way
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 …
Coming next: New EXTIO DLL for Cloud-SDR
This brand-new EXTIO DLL bring new (cool) features: Remote SDR stream selection (no need to change the configuration file anymore), Remote spectrum display Remote Chat and remote map integration And… tuning the remote SDR with DJControl through Midi interface, following F5OEO idea Watch the following Youtube video to see how the DJControl jogs are used …
Cloud-SDR server update released (build [20170118] )
The SDRNode streaming server has been updated to build [20170118] with improved support for the SDRPlay RSP2 and bug fixes in the Web Wizard. Changelog : Fix: a stream that has been created through the web wizard does not start and sdrnode service must be rebooted, better management of SDRPlay RSP2, antenna A/B port managed …
Local or Remote SDR ? What are the options ?
(originally published in August 2016 – This post has been updated) Background Local only Internal network Going outside… connecting the SDR device to the Internet Cloud-SDR proposed approach To summarize Links Background In this post we review the different techniques and architectures available to process RF samples coming from an SDR device on the local …
New poll : Interaction with external Arduino
Remote control of the SDR receivers with SDRNode can also require to switch from one antenna to another, to control an external antenna rotator, to check solar panel voltage etc. This can easily be done with an Arduino but then comes the issue to connect the external hardware to the SDRNode program. (image from https://www.arduino.cc/en/Tutorial/Button ) …
Creating your first stream with the configuration wizard
A video tutorial showing how to create your first remote has just been published In this video, F4GKR explains step by step how to share 256 Khz of bandwidth from a RTLSDR dongle
Coming soon… AFE822x SDR-Net (Dual Channel) support
We recently received the excellent AFE822x SDR-Net (Dual Channel) receiver from Alex. This SDR has interesting features (from website): ● Synchronized (diversity) or separated (independent) Dual Channel reception mode ● 100 kHz to 30.00MHz continuous frequency range ● 2-x Direct sampling receivers ● Digital down-conversion ● Dual 12- bit 76.8 MSPS A/D conversion ● Up to …
