SDRplay has recently announced the upcoming release of their "nRSP-ST" networked receiver. The product appears to essentially be an RSP2 with built-in computing and networking. The idea is that this networked receiver will be used remotely, and connected to over a local network connection or the internet.

The device will work with SDRplays SDRConnect software and will be able to transfer RF data in three modes, Full IQ, IQ Lite, and Compact. In IQ lite mode, only the active channels' IQ data are transferred, saving on significant network bandwidth when compared to full IQ mode.  In compact mode demodulation is carried out on the nRSP-ST itself, and compressed demodulated audio is sent over the network, saving on network bandwidth even more.

There are no details yet about the build, but we assume the internal computer is something like a Raspberry Pi 4 compute module or similar.

SDRplay is demonstrating a new product at the UK Hamfest today in newark, UK.  It’s an all-in-one, plug-and-play networked receiver which will launch later in the year.

SDRplay Limited is announcing the imminent launch of the “nRSP-ST”, an All-in-one, Plug-and-play Networked SDR Receiver.   The “nRSP-ST” is being demonstrated publicly for the first time at the UK National Hamfest in Newark today.

This exciting new product 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 have also introduced the ability to control and store IQ recordings at the remote location.  We think the nRSP-ST will be 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. We are very much looking forward to making the product available as soon as possible.  We are aiming to launch the nRSP-ST in time for the holiday shopping season and aiming at a price of just under $500 USD before tax.

The nRSP-ST key features:

• A truly “plug and play” integrated, networked general coverage receiver:
  • Combines a receiver, a host computer and a whole lot more – all in one box!
  • Apply power and connect to the internet (Ethernet or Wi-Fi) and the nRSP-ST is automatically accessible from anywhere
• The 14-bit ADC full featured wideband SDR receiver covers all frequencies from 1kHz through VLF, LF, MW, HF, VHF, UHF and L-band to 2GHz, with no gaps
• Remotely monitor up to 10MHz of spectrum at a time from a choice of 3 antennas
• Multi-platform SDRconnect^TM software supports local operation or remote access on Windows, MacOS or Linux platforms
• The nRSP-ST & SDRconnect^TM are configurable for available network bandwidth:
  • In “Full IQ” mode, the nRSP-ST provides IQ data transfer of the visible spectrum bandwidth (e.g.for high-speed LAN or superfast internet connectivity)
  • In “IQ Lite” mode, the nRSP-ST provides IQ data of channels up to 192kHz wide (e.g. for digital decoding by the client)
  • In “Compact” mode the nRSP-ST provides compressed audio (ideal for slower internet connections)
  • Supports multiple client connections with a simultaneous mixture of connection modes
  • All modes support visualization of up to 10MHz spectrum bandwidth
• Two remote connection options:
  • Use a remote SDRconnect client or
  • Use the built-in web-server for remote access from any web browsing capable device, including Android/iOS tablets and phones
• The nRSP-ST offers the ability to record IQ and audio files to a NAS (network attached storage) device if available on the LAN.
• Flash upgradable for future feature enhancements
