SDRplay Limited has announced the launch of a new Software Defined Radio product – the RSPdx.

The RSPdx is a replacement for the highly successful RSP2 and RSP2pro SDR receivers, which have been extensively
redesigned to provide enhanced performance with additional and improved pre-selection filters, improved
intermodulation performance, the addition of a user selectable DAB notch filter and more software selectable attenuation
steps . The RSPdx , when used in conjunction with SDRplay’s own SDRuno software, introduces a special HDR (High
Dynamic Range) mode for reception within selected bands below 2MHz. HDR mode delivers improved intermodulation
performance and fewer spurious responses for those challenging bands.
The SDRplay RSPdx is a single-tuner wideband full featured 14-bit SDR which covers the entire RF spectrum from 1kHz to
2GHz giving up to 10MHz of spectrum visibility. It contains three antenna ports, two of which use SMA connectors and
operate across the full 1 kHz to 2 GHz range and the third uses a BNC connector which operates up to 200MHz.
The RSPdx also features a 24 MHz ‘plug and play’ reference clock input which allows the unit to be synchronised to an
external reference clock such as a GPS disciplined oscillator (GPSDO)
Due to its exceptional combination of performance and price, the RSP family of receivers have become very popular, and
the RSPdx builds on the learning and feedback from many thousands of users across the amateur, scientific, educational
and industrial SDR community.
As was the case for the other RSP family members, SDRplay will work with developers of the popular third party SDR
receiver software packages to maximise compatibility. SDRplay will also provide multiplatform driver and API support
which includes Windows, Linux, Mac, Android and Raspberry Pi 3 and 4.
The RSPdx will be available to purchase in the next few weeks and is expected to retail at approximately £159 GBP or
$199 USD (excluding taxes).

The SDRplay RSPdx is a complete redesign of the popular RSP2 and RSP2pro multi-antenna receiver. 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. RSPdx Multi-antenna port 14-bit SDR
