SDRplay RSPdx-R2 1 kHz - 2000 MHz Wideband SDR Receiver

New! SDRplay introduce the RSPdx-R2, an enhanced version of the popular RSPdx model.

A wideband full-featured 14-bit SDR covering the entire RF Spectrum from 1kHz to 2GHz, with three software selectable antenna inputs and an external clock input.

The main design enhancements are:

1. Significantly improved noise performance below 1MHz (i.e for some MF, LF and below)

2. Improved dynamic range below 2MHz both in tuner mode and HDR mode.

Used in conjunction with SDRplay’s own SDRuno software for Windows, or Multi-Platform SDRconnect, the RSPdx-R2 offers the functionality to monitor up to 10MHz spectrum at a time.

The RSPdx-R2 features a 24 MHz ‘plug and play’ reference clock input which allows the unit to be synchronised to an external reference clock, such as Leo Bodnar's GPS disciplined oscillator (GPSDO), also available from our Webshop

The Receiver comes fully assembled and tested, and requires a Personal Computer, one of the SDR Receiver Application programs as well as a suitable antenna to provide excellent communications receiver functionality.

        Key Features

  • 14-bit SDR Receiver covering all frequencies from 1 kHz through VLF, LF, MW, HF, VHF, UHF and L band to 2GHz, with no gaps

  • Receive, monitor and record up to 10 MHz of spectrum at a time

  • Significantly improved noise performance below 1MHz (i.e for some MF, LF and below)
  • Improved dynamic range below 2 MHz both in tuner mode and HDR mode
  • HDR Mode below 2 MHz giving overall dynamic range and selectivity advantages
  • Supports up to 3 simultaneously connected antennas (2 x 50 Ohms and 1 BNC Connector for lower frequencies)

  • External clock input and output for synchronisation purposes, or connection to GPS reference clock for extra frequency accuracy

  • Excellent dynamic range for challenging reception conditions

  • Free use of Windows-based SDRuno software, or SDRconnect SDR and server software for Windows, MacOS and Linux

  • Multiplatform driver and API support including Windows, Linux, Mac, Android and Raspberry Pi 4/5

  • Housed in strong steel case

Free Professional Software

When used together with SDRplay’s own SDRuno SDR Software, or new SDRconnect Software, the RSPdx-R2 becomes a high performance general coverage receiver or spectrum monitoring instrument for the lab.


  • World Class SDR software for Windows, MacOS and Linux

  • Multiple ‘virtual receivers’ for simultaneous reception and demodulation of different types of signals within the same receiver bandwidth
  • Calibrated S meter/RF Power and SNR measurements with SDRuno

  • Ever-increasing feature set

  • Documented API for new applications development

Antennas for SDRplay Receivers

New to SDR Kits

The CCW Loop Antenna is ideal for use with SDRplay Receivers where outside wire antennas cannot be used due to lack of space.

We also offer popular L-band Patch Antennas for experimentation with Inmarsat and Iridium satellite frequencies.
