SDRPlay RSPDX Radio Receiver Review and Demonstration

RSPdx Multi antenna port 14 bit SDR

The SDRplay RSPdx is a complete redesign of the popular RSP 2 and RSP 2 pro multi antenna receiver. It’s a wideband full featured 14 bit SDR which covers the entire RF spectrum from 1 kHz to 2 GHz. Combined with the power of readily available SDR receiver software (including SDRuno supplied by SDRplay) you can monitor up to 10 MHz 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.

KEY BENEFITS & FEATURES:

  • 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
  • Performance below 2MHz substantially enhanced improved dynamic range and selectivity
  • Software selectable choice of 3 antenna ports
  • Enhanced ability to cope with extremely strong signals
  • 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 which provides an ever increasing feature set
  • Strong and growing software support network
  • Calibrated S meter/ RF power and SNR measurement with SDRuno (including datalogging to .CSV file
  • Documented API provided to allow demodulator or application development on multiple platforms
