Note moyenne : 5/5 Nombre d'avis : 1

The new SDRPlay RSPduo is a 14-bit SDR dual receiver that covers from 1kHz to 2GHz (without hole), with dual-tuner (simultaneous reception on 2 different antennas).

The SDRDuo is equipped with a software-adjustable LNA, 11 band filters and 3 antenna connectors, 2 female SMA and 1 Hi-Z input to connect a HF wired antenna (0-30Mhz) with Notch filter and low pass 0-2Mhz, TCXO 0.5PPM, clock function and 4.7V Bias-T power supply via SMA.

The 2 SMA inputs now operate from 1 kHz (instead of 1.5Mhz) with 0-2 MHz low-pass filter to reduce spurious frequencies in LF and MW.

Works on Windows with SDRuno software (free) and on Linux with Gnu Radio Companion, GQRX and CubixSDR.

Delivered with: SDRPlay RSPduo metal case (delivered without USB power cable).

See below the recommendations for use, installation and support request SDRplay.

Recommendations and support

1 - Do not connect the RSPDUO directly to the same antenna as your transmitter, or to an antenna in the near field of a transmitting antenna as this may cause irreversible damage.

2 - The RSPduo is sensitive to electrostatic discharge which can damage the receiver if not protected or used correctly. It is recommended to disconnect the antenna in case of severe weather and to ensure an earthing of the antenna. Before reconnecting the coaxial cable after a thunderstorm, it is imperative the unloader (braid and core) to the ground.

In these 2 cases of loss of reception and RF damage, the warranty will not apply and the equipment neither repaired, exchanged or refunded. The signs of RF damage are characterized by signs of hot on or around components near the signal input, a burning smell is also an indication of RF damage.
