In the meantime I'm impressed anew everytime I operate the Duo as a digi-mode receiver.

The link shows the results, along with a comparison with the levels shown using SDRuno.

One thing to point out is that currently the Ref-dBm level and Input offset controls only effect the display and have no effect on the Duo's (or any other RSP's) gain or signal attenuation. In the actual beta release, these controls will control the device's gain so that operation will be more in line with what you Steve Andrewnoreply@blogger.comtag:blogger.com,1999:blog-1142737426092510126.post-43710466271331753942018-06-26T09:53:59.516-05:002018-06-26T09:53:59.516-05:00Hi from SDRplay.
