One can do this with the NCDXF Beacons ... they change in four 10 dB
steps, 100 W, 10 W, 1 W, and 100 mW. No sunspots right now, but you
might be able to hear one or two of them on 14100. Most interesting
thing I notice is, while the 100 W signal may be S6 in S2 noise, I can
still hear the 100 mW signal which should be 40 dB down [~S0]. The math
is sound and exact, the reality ... not so much.

Sometime in a QSO have the other station increase or decrease the
signal by 3db. it will not be that noticable. now turn off AGC and
ask the other station do it again it will be much more evident. than
with AGC on.
With more than one signal present say in a pileup the different will be
noticeable because the weaker signals will seem quiter when a strong
signal comes in. its all relative.
