The new RSPduo from SDRplay was released at this year’s Hamvention in Dayton and provides a dual tuner SDR receiver.
Each of the two tuners can operate independently and on any frequency between 1kHz and 2GHz, with no coverage
gaps! Based on the same Mirics chipset as previous models, the new RSPduo employs new filter combinations and retains the signal level measurement facility introduced last year. To complement the new receiver, a new
version of their SDRuno software is available for free download from the SDRplay site.
The provision of dual tuners is an interesting idea that opens up many new possibilities.
Fairly obviously this means you can monitorany two frequencies between 1kHz and 2GHz with the same receiver. However, the more exciting prospect is the potential for noise cancellation using diversity reception
techniques. For those unfamiliar with the concept, this is where your main antenna is
connected to one receiver and a secondary (noise) antenna is connected to the second
receiver. The outputs from each receiver are then mixed using an adjustable phase
shifting network. In a practical system, you alter the mixing parameters until you achieve
the best null in the noise level. The benefitscan be significant, and I’ve seen 20dB of….. READ FULL REVIEW
