[600MRG] measuring noise level ?

[Pat Hamel]

The point is that a station with an S-8 noise level on 600 meters (like
WD2XSH/6 before I gave up) will be reduced to beaconing because he can't
hear anything else, but the station with low noise is the one to email and
ask to check your signal when you change something.
Knowing noise level and geographic location comes in handy if you want to
make nightly schedules.
 When I could hear something, I scheduled a station in New York for
temperature reports nightly one season.

P.S. The transmitter amp is still available for someone who will pay postage
or pick it up - see QST mar 2008.

What is the point of a number like -85dB?  dB compared to what?  And without
a standardized antenna system, what's the point of sharing it with others?\

The number might be useful for comparisons at the same installation from day
to day, or before and after some change, but it remains a relative
measurement - not absolute.  And definitely not useful to compare to other
stations with different antenna systems.
