- Jul 1, 2012Roelof, thank you for that perspective. I always try to log “C/N” (Carrier-to-Noise)...can be same thing as S/N I suppose. C/N must be a hangover from my satellite days.Mark Durenberger

The only thing that counts is the signal to noise ratio.
Look e.g. at the same antenna used at home or at a field location.
It had a 9 dB higher noise floor in the field, however still weak signal
work was better due to a better signal to noise ratio.
Working for the lowest possible noise floor with the same antenna is the
way to go.
This is a tricky game and I use stations within close range for testing.
The noise will often vary over the band and this should be taken into
account as well.
However, the PERSEUS is a very nice tool to evaluate your noise situation.
For a wide band view, HF-Span is very nice indeed.
And very educational!
