SDRuno: SDRplay introduces a free native app for the RSP

(Source: SDRplay Press Release)


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

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.

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.

    Amazing how fast they got this done, but I’m kind of disappointed to learn it’s based on Studio1. I just happened to download the demo version yesterday, and while beauty is always subjective, I thought it was ugly as a tree full of owls and completely unintuitive. With only demo files to play, it was impossible to gauge how well it would have worked with the SDRplay. I’m glad there’s a SDRplay specific version and I look forward to trying it with my own setup. I can live with ugly (I use HDSDR regularly) if it is a performer.

    One thing that *immediately* set me off down a bad path was when trying the Studio1 demo and a download of SoDiRa, is both apps launched windows that were fully top-left on my screen, hiding under the task bar. Nothing pisses me off quicker than an app that gets up under the taskbar and can’t be moved or enlarged. The only solution is to move the taskbar! Why some apps don’t respect a taskbar on top in Windows is beyond me. It’s a stupid thing but it makes me mad to no end!

    This might be welcome since one of the limitations of SDRplay is supposedly its poor AGC during AM mode. I hope someone can test the new software and do a direct comparison to other software.

    Wow – they got this done sooner than I thought they would – and it’s free!?!

    So many knobs to twiddle on this, I’m going to have to crack the manual.
    Thanks for the article and thanks for this fine software!
