On Sunday evening, before dark, signals were being picked up nicely here in UK -with stations from Lebanon, North and South America. This was our live stream where we demonstrated the use of admin control for timeouts and how multiple users can share the receiver simultaneously albeit with restrictions to the same part of the spectrum as the “controller”:
The April 2025 edition of Practical Wireless has a review of the nRSP-ST:
The article is descriptively headlined “The Sharing Machine”
In the review on pages 16-19, Georg Wiessala puts the nRSP-ST through its paces and comments “The new nRSP-ST is a gamechanger, a milestone… it makes a substantial addition to the funtionality of your shack, if you wish to make use of the networking facilities and the built-in web server… in the context of the radio hobby, this is indeed groundbreaking and a big leap forward”

At last there is a replacement for the popular MFJ1708B-SDR T/R switch which protects your SDR from damage from your transmitting signal. It’s the new SDR switch from N2EME ( SDRSwitch.com )
These are now available from Martin Lynch and Sons and in this new ML&S video, David, M0TPT shows it in action with an SDRplay RSPduo – 1 minute 25 seconds in:
David doesn’t show how to set up rig control, but this video demonstrates how to do it using SDRuno with the obsolete MFJ1708B-SDR. (Please note we are working on rig control for SDRconnect which will be released soon).
The March 2025 edition of Spectrum Monitor Magazine is out and Georg Wiessala has written this in-depth review of the nRSP-ST (see pages 32-26)
In it, Georg writes “In my view, this receiver beats any homebrew, web-based or Raspberry Pi related construction solution hands-down – in terms of the signal range it covers, its ease of use, shielding and construction, openness to experimentation and radio education, and the expected future developments. You will need a rudimentary understanding of PCs, the internet, routers and networks, but will not need a PhD in Computer Science to operate this radio. Highly recommended. “

Have fun blasting SDRconnect though your car stereo system. Tune into your favourite nets or DX frequencies. Access FM broadcast stations you can no longer stream when travelling abroad (The BBC Sounds App will only offer Radio 4 and the BBC world service for Brits abroad, starting this spring!) The nRSP-ST is your personal SDR radio receiver for you to access wherever you are, on whatever device is handy, including Tablet or Phone. Share access with a small group of trusted friends. For more on the nRSP-ST go to: https://www.sdrplay.com/nrspst/ Many thanks to Rick Kunath (K9AO) for pointing out the power of this capability!
Changes to BBC Sounds: https://www.bbc.co.uk/sounds/help/questions/recent-changes-to-bbc-sounds
As well as restricting access to BBC radio programmes for Brits abroad, they will increasingly detect attempts to bypass this using a VPN. So your very own nRSP-ST could be the answer. Wherever you roam, you can connect to you personal SDR and have those broadcast stations at your fingertips again!
Your home FM stations accessible via your phone+bluetooth car stereo around the world!
The February 2025 edition of the Radio Society of Great Britain’s monthly magazine RadCom featured a review of the nRSP-ST by Steve Nichols.
Steve tests the nRSP-ST and comments that “it marries a high performance SDR receiver with a built in computer to give fully-networked access to the receiver” and goes on to say “the nRSP-ST is a novel device which enables you to monitor the bands while sitting in your lounge as well as from anywhere else”.

Those of you who have been following SDRplay over the years may remember our encouragement for people to innovate around creating stand-alone SDR receivers with integrated computer and screen. As long ago as 2019, we demonstrated such a device by embedding an RSP1A inside a Raspberry Pi based Pi-Top laptop computer. This was the article: https://www.sdrplay.com/a-self-contained-laptop-sdr-receiver-using-an-rsp1a/
An RSP1A inside a Pi-Top compter in 2019
We have also demonstrated compact designs at various shows over the years using integrated Rapsberry Pi with 7 inch display and even with a mini PC:
An RSP1A plus mini-PC on the back of a monitor
Cheap Russian and Chinese all-in-one SDRs have emerged providing a partial solution, albeit with some significant performance and reliability limitations.
More recently, we introduced the new networked SDR, nRSP-ST which integrates a host computer to provide a truly plug-and-play personal remote-access SDR receiver. For this your remote computer can be anything from a Mac, a PC, a tablet or even a phone.
But here’s another new option – Tech Minds have just brought out a new YouTube video giving step by step instructions on how to create a compact radio using a PiHPSDR together with an SDRplay RSPdx…. so many choices 🙂 ………………………
We have sold all of the first production run of the nRSP-ST networked receiver – our channel partners and resellers took all that we made first time round – so much so, that we were unable to sell any units directly from our website. (latest news – February 16th update We aim to ship to most resellers so that they have stock on their shelves by February 24th.
It’s important to contact your preferred reseller to let them know of your interest so that they don’t sell out from this new batch of units.
More about the nRSP-ST
The nRSP-ST is your own personal remotely accessible SDR which can also be shared with a small number of trusted friends or colleagues.
The nRSP-ST addresses the needs of radio enthusiasts who want a ‘plug-and-play’ solution for remote reception. As well as achieving this, we have addressed typical internet bandwidth limitations with the creation of a novel “IQ Lite” mode, which efficiently delivers channels of IQ data. We are also introducing the ability to control and store IQ recordings at the remote location. The nRSP-ST is ideal for anyone wanting a wideband remote receiver without needing computer skills and hours of set-up time and ongoing maintenance at the remote location.
