Re: Noise Floor


 

Generally when my spectrum is all yellow & angry, I crank in some receive
attenuation.

Hey 'yall,
I'm still working off a 2' wip in the basement, so not the best
environment. Lots of noise on 20M but still picking up 4's and 5's
!!! Anyhow, I may misunderstand what the book (3rd ed) is saying but
when I adjust the noise floor, the spectrum goes UP and the waterfall
colors get more out of wack (my opinion). I mod'ed the code to allow
the Noise Floor to go negative and it does what I was
hoping/expecting/understanding.
Is there something here I don't understand? Do I misunderstand what
the book is saying? I'm running the latest 66.9, v12. I'm still
working my noise problems.
Thanks
