SDRplay Releases SDRuno: Free SDR Software for the RSP

The SDRplay is a $149 USD RX only software defined radio with a 12-bit ADC and up to 8 MHz of bandwidth that can tune from 10 kHz – 2 GHz. We consider it and it’s competitors the Airspy R2/Mini to be the best next step up from an RTL-SDR. See our previous post for a review comparing the Airspy and RSP.

One of the main drawbacks of the RSP has been that it does not have any official software associated with it. The closest competitor, the Airspy has the free official SDR# software, but the RSP relied only on third party programs like HDSDR and SDR-Console.

That is set to change today as SDRplay have announced the release of their SDRuno software, a free general purpose software defined radio program for the RSP. SDRuno is a customized version of the Studio1 software which SDRplay acquired the rights to last April. The full press release is quoted below:

SDRplay is pleased to announce the official release of SDRuno for the RSP. SDRuno is the new name for the RSP compatible version of Studio1, the rights to which we obtained and announced on 28th April. SDRuno contains native support for the SDRplay RSP and no extra plugins are required. Third party hardware can also be supported via the ExtIO interface, but with reduced functionality.

SDRuno provides a rugged and flexible, high performance SDR receiver capability and boasts some excellent features:

  • Multiple ‘Virtual Receivers’ which allow for simultaneous reception and demodulation of different types of signals within the same receiver bandwidth.
  • A selectivity filter with an ultimate rejection greater than 140 dB.
  • A unique distortion-free double stage AGC with fully adjustable parameters.
  • Multiple notch filters with BW adjustable down to 1 Hz, Notch Lock feature.
  • A unique synchronous AM mode with selectable/adjustable sidebands, dedicated PLL input filter, and selectable PLL time constants.
  • SNR (stereo noise reduction), featuring a proprietary noise reduction algorithm for stereo broadcast.
  • AFC for FM signals.
  • Calibration for receiver frequency errors.

Over time, we plan to add many more features to SDRuno to enhance the user’s experience of this very powerful piece of software. This software runs on Windows and we don’t yet know how easy it will be to migrate it to other platforms but this is something we will be investigating.

SDRuno will be made freely available to all current and future users of the RSP – to download a copy – simply go to http://www.sdrplay.com/windows.html

Our support for SDRuno in no way lessens our commitment to support HDSDR, SDR Console, Cubic SDR or ANY other software solution where the authors are willing to work with us. We fully recognise that many people have strong preferences for particular pieces of software and we do not want to do anything to undermine the options that people have to use their favoured software packages. Indeed, our view is quite the opposite. Our objective remains aim to have our hardware platforms support any and every SDR package out there. This of course may not be possible, but it is our philosophy and part of the ethos of our company.

About Studio 1:

Studio1 was developed in Italy by SDR Applications S.a.s. and has hundreds of happy customers around the world.

Studio 1 is known for its user friendly stylish GUI, CPU efficiency and advanced DSP capabilities, including features not available on other SDR software packages.

The software can be downloaded at http://www.sdrplay.com/windows.html. SDRuno comes with a full manual (pdf) and SDRplay fans and beta testers of SDRuno have also released a free SDRuno cookbook guide (pdf). From the cookbook it appears that SDRuno is also compatible with any SDR that supports ExtIO modules, like the RTL-SDR, although as noted in the press release functionality for other radios may be reduced. We look forward to being able to test the software out, and post a review within the next few days.

    I feel very upset, you advertise this product as working on Linux It dos not.
    Win 7 NO unless the resolution is very high.
    Why do you not publish minimum requirements.
    Why do you not answer your followups when the system will not work.
    So far many hours of work and over 120 quid wasted.
    All my other SDR dongles work on Linux and Windows. your software is not up to the Job.
    Please explain.

  2. Robert Long

    Yeah… until it comes out for MAC… sorry, I cannot buy. And unfortunatly, I will not run a virtual.. (I like to multi task with other mac windows open…virtual will not allow this)
    I’ll keep checking back (as will MANY others to buy when a MAC version comes out)

    Hopefully, soon!
    🙂

    • Mark

      Yeah I want a MAC version too, Linux and Mac users always suffer.

      An easy install for Ubuntu and Arm7 devices would be nice too.

    • Ken

      Yes indeed. A Macintosh version please, and one that radio geeks as opposed to computer geeks can understand how to install. Please. Pretty Please? 🙂

    • Robert Dale

      Strange, I run a VM on my iMac which runs HRD 5.0 and either PowerSDR or Nap3 beside all my Mac programs, no problem at all. No glitches, latency issues or sound problems. That said, a native OS-X version would be nice.

    Will SDRUno support MSPS higher than 0.96 so third party hardware other than RTL-SDRs can be used with SDRUno? Airspy R2’s lowest is 2.5 MSPS and Airspy Mini’s lowest is 3.0 MSPS.

    Latest news from SDRplay re updates for SDRuno: We are aware of a number of issues, bugs and feature requests. We will be addressing these in a series of updates. Some of the feature requests will take some time as we are determined to implement them correctly and make them intuitive. With that in mind, SDRuno version 1.1 will be released around the end of August and will consist largely of bug fixes. We expect to make further regular updates after that to address some of the other issues and features we’ve all seen and been thought about. We are also going to be producing some webinars with the aim of not only getting people familiar with SDRuno, but to help people achieve specific tasks. We will be providing more details about these in the next couple of days.

    Other software updates: Our immediate priority is to release the new API and EXTIO so that we can deliver the recent enhancements (VLF coverage, performance improvements, higher sample rate and improvements for developers, etc.) to users of the other popular software: SDR Console (working with Simon Brown) and HDSDR (via our updated EXTIO interface) We aim to have the release of both of these during the first week of July. We will then produce an update to the SoapySDRPlay library to support CubicSDR (Charles Cliffe).

    Meanwhile Paul and Mike have made a major update to the SDRuno Cookbook, which now includes setup for CSVUserlistbrowser, a great database setup that allows for rudimentary scanning… V1.003 now runs to 28 pages http://www.nn4f.com/sdruno-cookbook.pdf

    CoolSmooth,
    “pis off”? thats foul language! 🙁
    And why do you want to run a desktop application on IOS?
    And why so anally annihilated? You said you got a windows pc/partition, so why do you want it on OS X? (i guess thats what you’ve meant)
    Why return it? you know, you can also use it with other software packages, just saying.
    Also, they said they might port it;
    ever heard of virtual machines or WINE?
    paws

  6. CoolSmooth

    I’m very upset that there is no IOS version of SDRuno! Therefore I am returning the SDRPlay to HRO, deleting SDRuno from my Windows systems and boycotting SDRplay. They will learn not to pis me off

    Competition is a very good thing. By providing their own software to interface with the RSP, they are no longer at the mercy of a third party to provide support for the RSP. This is great news! Personally, I would have been willing to part with cash for SDRuno.

    SDRuno works great with my RSP. It can be complicated to correctly setup, operate, and get used to – just like the other SDR packages already out there. It’s akin to the differences between operating Agilent and Tektronix spectrum analyzers. You can perform the same functions with both … how you go about it differs.

    Personally, I’m not worried about who is catching up to who. The RTL-SDR provides a solid and extremely affordable product. It has single-highhandedly gotten me excited about radio again. The SDRplay RSP and Airspy products provide improved dynamic range, frequency coverage, and instantaneous bandwidth. Pick anyone or all of them. Just enjoy what has been made available and explore.

    Seems to work pretty well with the RTLSDR. Looks like you’re limited to a .25Msps rate though, unless I’m missing a setting somewhere. A bit of a learning curve to the whole thing but overall I like it.

  9. 1234

    I’m trying to understand the logic in your post. Can you give me some type of example as to what the other company or companies might be?

    I guess if SDRPlay does port to Linux and they don’t port to OS X with SDRuno they will all be doomed to the pits of SDR hell.

    • Marty

      The funny thing is if you provided a version of software for Windows, OSX and Linux then someone would be complaining about no ARM support and if you had ARM support then someone else would complain about no *BSD support on Sparc architecture.

      The moral is that no one can ever please everyone, it is best to chase after the largest market segment and work your way down to the fringe and always set a cut-off point less than X percent of total users you wanted to be on your own, so you are on your own.

    • Noodle

      Nonsence. Aiming at the majority in the first instance, if far from a mistake – it’s smart business. And as your’ve not noticed, Android is also supported, you noodle.
