Adjusting RF Gain on the Antenna -- which 'noise floor' do I use?
Hi guys (and gals, of course!)
I'm trying to adjust the RF Gain on my new to me 6700 and dutifully following the instructions Tim provides in his 2019 article. I'm kind of stuck tho, on trying to determine the 'no antenna noise floor' I'm supposed to be using as a reference.
Here's a screenshot of what I see on 80m with no antenna connected, CW, 500hz bandwidth, no noise reduction, etc.
My query regards the apparent difference in noise floor measurement/display between the panadapter (looks like about -120dBm) and the S meter in the flag showing -110dBm. Which one should I use in determining the noise floor? And which one should I use in determining if there is a 8-10db difference when I add an antenna and the RF Gain?
Thanks for your help.
