Antenna and SDRplay set-up for HF diversity reception (rev1)

This video shows the antenna set-up, and an HF diversity reception demo using the RSPduo. It illustrates the benefits possible with this 7MHz amateur radio SSB signal example. (This video replaces an earlier version where the audio volume was too high during the demo itself) This video demonstrates how SDRuno diversity and the RSPduo can bring enhanced reception at HF using 2 antennas separated by approximately a quarter wavelength. It uses the the current version of SDRuno (V 1.32) and the dual tuner RSPduo SDR from SDRplay. In this experiment we had a wire dipole with one leg approximately a quarter wavelength from a Boniwhip vertical - both were picking up similar strength signals before going into "diversity" (max ratio combination) mode. The benefits of diversity tuning at HF are very dependent on many variables, most notably the changing nature of the reflected signal path and the degree to which noise and unwanted signals are not as coherent as the wanted signal. We look forward to learning more about all these inter-dependencies - we encourage experimentation! See also how the manual use of diversity tuning for noise reduction can be very powerful: https://www.sdrplay.com/video-demo-sh... More about the new SDRuno diversity software can be found here: https://www.sdrplay.com/new-sdrplay-d... This is possible in an RSPduo, due to the coherent nature of the combined tuner streams being presented to the computer for processing. This is one of many video guides from SDRplay - makers of the RSP family of SDR radios. See the full list of SDRplay videos and applications documents on: https://www.sdrplay.com/apps-catalogue/ The RSP family of SDRs from SDRplay cover 1kHz to 2 GHz with no gaps and give up to 10MHz spectrum visibility. SDRplay is a UK company. The RSP SDR receivers are made in the UK and can be purchased for worldwide delivery directly from http://www.sdrplay.com/ (click on purchase and select your country to view shipping costs) or you can buy from any of our worldwide resellers listed here: http://www.sdrplay.com/distributors/ Many of the resellers offer local free shipping and/or local language technical support.
