Model: RSPDX
Availability: On stock
Average Rating: Not Rated
Manufacturer: SDRplay


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.

Az SDRplay RSPdx SDR 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. Plus 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.

The SDRplay 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.

SDRplay RSPdx SDR radio 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 capability)
  • Documented API provided to allow demodulator or application development on multiple platforms

RTLSDR through the eyes of an SWL observer over the past 8-10 years

SDR radio became popular in Hungary around 2012-2013 thanks to the RTL chip versions appearing among DVB-T Chinese USB TV receivers. Back then you couldn’t get these devices in Hungary, you had to order them from China. Since then the situation has changed a lot here, too.

Introducing the new 5W Dual Band Digital Transceiver – Yaesu FT3DE!

The new Yaesu FT3DE provides reliable 5W RF power output in compact design and light weight from factor - W62mm x H100mm x D32.5mm/ 282g. Battery power-saving settings are available for each frequency band with TX output power level (5W/ 2.5W/ 1W/ 0.3W) individually selectable. Even in a compact body, the user can enjoy loud and clear C4FM voice quality from 700mW of audio power. Real Dual Band Operation (V+V, U+U, V+U, U+V) are available with two independent receivers, and the FT3DR/E supports simultaneous C4FM digital monitoring for both the A and B bands (C4FM/C4FM standby).

SDRplay is pleased to announce the release of SDRuno v1.3. SDRplay is pleased to announce the release of SDRuno v1.3. This is a major upgrade to SDRuno, which adds a number of important new features and is intended for all RSP models (RSP1, RSP1A, RSP2, RSP2pro and RSPduo)
PDN (Portable Digital Node) function for the FTM-400 and FTM-100 We are excited to inform that the PDN (Portable Digital Node) function for the FTM-400 and FTM-100 series is now available. This firmware is now available at Yaesu official website: http://www.yaesu.com
Raspberry Pi 3 + SDRe receivers It is clear that an excellent way to attract newcomers to the radio hobby is via the Raspberry Pi plus an RSP.  SDRplay has made available a downloadable SD Card image which is ideal for this.
