SDRplay

SDRplay RSPdx/Duo HF/VHF/UHF


SDRplay produces a range of inexpensive HF/VHF/UHF SDRs. The big advantage is that HF/VHF/UHF is all integrated in one device.
This ensures fast switching between HF and VHF/UHF. Another nice feature is the built-in antenna switch.
The receivers can be used with go2MONITOR, SDR-Console or SDRuno/SDRconnect.

Key Facts

  • go2signals support
  • Enhanced ability to cope with extremely strong signals
  • Choice of 3 antenna ports
  • External clock input for synchronization purposes (GPS)
  • Rugged black painted steel case
  • USB interface

SDRplay RSPdx

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.

SDRplay RSPduo

The RSPduo is unique with its dual tuner and diversity tuning function.

SDRplay

The SDRplay is supplied with a metal housing.
It is a good choice if HF and VHF/UHF are to be covered.
The antenna switch is also useful if several antennas are present.
