RSPduo Dual Tuner 14 – Bit SDR


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 the spectrum at a time (single tuner mode)
  • External clock input and output for synchronisation purposes, or connection to GPS reference clock
  • Software upgradeable for future standard Strong and growing software support network
  • API provided to allow demodulator or application development

The RSPduo is a high-performance dual-tuner 14-bit SDR receiver. Housed in a high-quality steel enclosure, each tuner can operate individually anywhere between 1kHz and 2GHz with up to 10MHz of bandwidth or both tuners can operate simultaneously anywhere between 1kHz and 2GHz with up to 2MHz of bandwidth per tuner. A high stability reference along with external clocking features makes this device ideally suited to industrial, scientific & educational applications.

  • 3 software-selectable antenna ports ( 2 x 50 and 1 x 1k ) high impedance balanced/unbalanced input)
  • 14-bit ADC silicon technology /li>
  • Up to 10MHz visible bandwidth (single tuner mode) or 2 slices of 2MHz spectrum (dual tuner mode)
  • 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
  • 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
