Manufacturer: SDRplay


The SDRplay RSPduo is a dual-tuner wideband full featured 14-bit SDR receiver, which covers the entire RF spectrum from 1kHz to 2GHz giving 10MHz of spectrum visibility. Combined with the power of SDRuno software for Windows, you can simultaneously monitor two completely separate 2MHz bands of spectrum anywhere between 1kHz and 2GHz. The RSPduo SDR receiver provides three software selectable antenna inputs, and clocking features ideally suited to industrial, scientific and educational applications. All it needs is a PC and an antenna to provide excellent communications receiver functionality. A documented API allows developers to create new demodulators or applications around the platform. 

SDRplay RSPduo SDR receiver key benefits:

  • Simultaneously receive on two totally independent 2MHz spectrum windows anywhere between 1kHz and 2GHz
  • Simultaneous processing from 2 antennas enables direction-finding, diversity and noise reduction applications
  • Ideal for cross band full-duplex reception, e.g. HF + VHF or VHF + UHF
  • Simultaneous Dump1090 and VHF ATC reception
  • Simultaneous monitoring and recording of 2 ISM bands
  • 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 (single tuner mode)
  • External clock input and output for synchronisation purposes, or connection to GPS reference clock
  • Excellent dynamic range for challenging reception conditions
  • Works with popular EXTIO-based SDR software (available mid 2018)
  • Software upgradeable for future standards
  • Strong and growing software support network
  • API provided to allow demodulator or application development
  • Calibrated S meter/ RF power and SNR measurement with SDRuno (including datalogging to .CSV file capability)
  • Ideal for portable monitoring of ISM/ IoT/ Telemetry bands <2GHz
  • World-class technical support via www.sdrplay.com 

SDRplay RSPduo SDR receiver key features:

  • Dual tuner provides independent coverage from 1kHz to 2GHz using 2 antenna ports simultaneously
  • 14-bit ADC silicon technology (not another 8 bit dongle!)
  • Up to 10MHz visible bandwidth (single tuner mode) or 2 slices of 2MHz spectrum (dual tuner mode)
  • 3 software-selectable antenna ports ( 2 x 50Ω and 1 x 1kΩ high impedance balanced/unbalanced input)
  • High impedance antenna port (1kHz to 30MHz) with selectable MW notch filter and choice of 2 pre-selection filters
  • Software selectable AM/FM and DAB broadcast band notch filters for the 2 SMA antenna (1kHz to 2GHz) antenna ports
  • External clock input and output enables easy synchronisation to multiple RSPs or external reference clock
  • Powers over the USB cable with a simple type B socket
  • 11 high-selectivity, built in front-end preselection filters on both the 2 SMA antenna ports
  • Software selectable multi-level Low Noise Preamplifier
  • Bias -T power supply for powering antenna-mounted LNA
  • Enclosed in a rugged black painted steel case.
  • SDRuno—World Class SDR software for Windows
  • Documented API for new apps development

Kategóriájában meglepően jó eszköz.
Természetesen vannak határai ,amit az SDR vevőknél már megszokhatunk.( 2X10 MHz sweep)
Viszont nagyjelű viselkedésben,érzékenységben kifogástalan.
Összefoglalva: nagyon jó ár-érték arány.Preciz és robusztus kivitel,ami a kitelepülésekkor nem mindegy.

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.
