[600MRG] measuring noise level ?

[sbjohnston at aol.com]

I did not say there was no reason to be aware of noise - far from it.  In both my amateur and my professional life the problem of radio noise is a very big deal.  I just don't get the point of sharing a figure like "-85 dB".  

Decibels don't mean anything unless you provide the reference level to which your measurement is -85 dB down from.   

And without considering the gain or loss of the complete antenna system (or the bandwidth of the receive system in which you are adding up the noise) I can't see how you can compare station A to station B in a different location.
