Multi-antenna port 14-bit SDR

The SDRplay RSPdx-R2 is an enhanced version of the popular RSPdx and is a wideband full-featured 14-bit SDR which covers the entire RF spectrum from 1kHz to 2GHz. Combined with the power of readily available SDR receiver software (including ‘SDRuno’ for Windows and Multi-Platform ‘SDRconnect’ supplied by SDRplay) you can monitor up to 10MHz spectrum at a time. The RSPdx provides three software selectable antenna inputs, and an external clock input. All it needs is a computer and an antenna to provide excellent communications receiver functionality. A documented API allows developers to create new demodulators or applications around the platform.


  • Covers all frequencies from 1kHz through VLF, LF, MW, HF, VHF, UHF and L-band to 2GHz, with no gaps
  • Receive, monitor and record up to 10MHz of spectrum at a time
  • Significantly improved noise performance below 1MHz (i.e. for some MF, LF and below).
  • Improved dynamic range below 2MHz both in tuner mode and HDR mode.
  • Software selectable choice of 3 antenna ports
  • External clock input 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 and Multiplatform driver and API support including Windows, Linux, Mac, Android and Raspberry Pi 4/5
  • Calibrated S meter/RF power and SNR measurement with SDRuno


  • High Dynamic Range mode (“HDR”) for RSPdx use below 2MHz
  • Highly integrated native Windows support for the SDRplay family
  • Multiple ‘virtual receivers’ for simultaneous reception and demodulation of different types of signals within the same receiver bandwidth
  • An integrated frequency scanner and a selectivity filter with an ultimate rejection greater than 140dB.
  • A unique distortion-free double stage AGC with fully adjustable parameters
  • Multiple notch filters with BW adjustable to 1Hz + Notch Lock feature
  • A unique synchronous AM mode with selectable/adjustable sidebands, dedicated PLL input filter, & selectable PLL time constants
  • SNR (stereo noise reduction), featuring a proprietary noise reduction algorithm for stereo broadcast
  • Powerful wideband noise filter for addressing common sources of RFI
  • Calibration for receiver frequency errors
  • RDS support optimised for low signal environment
  • Active Noise cancelling
  • CAT and Omnirig control
  • Calibrated RF Power Meter and S-Meter supporting IARU S-Meter Standard
  • The ability to save power and SNR measurements over time, to a CSV file for future analysis
  • IQ output accessible for 3rd party applications
