OPver on his TechMinds YouTube channel Matt has uploaded a review of the SDRplay nRSP-ST networked software-defined radio which was released for sale just last week at a retail price of US$499.95.
A networked SDR like the nRSP-ST allows the user to set up the radio in a remote location, and easily connect to and use it remotely over a local network or internet connection. Similar devices include the KiwiSDR and Web-888 and of course, it is possible to achieve something similar with other SDRs that provide server software using a device like a Raspberry Pi as the server.
Matt first unboxes the nRSP-ST in the review and compares it in size to the RSPdx, noting it is about double the size. He then goes through all the I/O ports on the device, pointing out that it has an WiFi connector, Ethernet port, reference in, two SMA antenna connections for 1 kHz to 2 GHz, and one BNC for 1 kHz to 200 MHz.
Matt then opens the nRSP-ST’s lid, exposing the circuitry. He notes that it has a 1.5 GHz quad-core processor, 2GB RAM, 8GB eMMC, and the SDRplay radio circuitry. The computing hardware is covered by a soldered-down metal shielding can, but from the specs, we note that it sounds like a Raspberry Pi Compute Module 4 is used under the hood.
In the rest of the video, Matt shows how the remote software can be set up and updated. He then goes on to show the SDR Connect and browser-based software being used to receive signals with the nRSP-ST.
