You can see the RX I/Q output comes after the preamp, and so will be affected by the preamp setting. I have to say, if the band noise is so high as to make everything green on the screen, does it make sense to run the preamp? If your S-meter is moving with the preamp off, then you already have plenty of sensitivity for the conditions, and turning the preamp on becomes a little counter-productive. 73, Matt VK2RQ > On 14 Dec 2014, at 3:38 am, Thorpe, Jeffrey <[email protected]> wrote: > > I was under the assumption (yeah - I know...) that the IQ output was > "unmodified" by your settings on the radio.
