RSPdx, SDRplay Radio Receiver RF Spectrum Software Defined Radio Receiver for Aircraft (ADS-B and ATC), Antenna Research,

The SDRplay RSPdx is a major upgrade to the popular RSP2 and RSP2pro multi-antenna receiver design. It’s 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’ 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.

Features and Benefits

• 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 capability)


• Documented API provided to allow demodulator or application development on multiple platform
