We have been quite busy over the past weeks and this long silence may sound like the business is not ongoing here… Of course not 🙂 A major update is under final tests and we hope to release it by end of July so you will be able to enjoy multi user, multi hardware remote …
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. …
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. …
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 …
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 …
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 …
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 …
(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 …
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.
