Ken,
Check out a similar chart on the Elecraft website (Rig Comparisons) that
uses data from the ARRL Product test data. The test setup for the ARRL
tests is well documented. I did not see an indication of the setup used for
the particular tests that produced the chart you referred to.
Without getting too technical (but hopefully not incorrect through
simplification either),
The noise floor is an indication of the strength needed for a signal to be
heard above the receiver noise - the K2 is right on top of that list with
the Orion.
The narrow spaced dynamic range measured at a 2kHz spacing indicates how
well the receiver will tolerate a signal that is 2 kHz away. Checking the
notes on the recorded value indicates that that test measurement was limited
by phase noise, so the real number may be higher (better) than indicated.
The bottom line is that the K2 will hear weak signals on a crowded 40 meter
band as well as the competitive best receivers and will allow you to read
the desired signal in the presence of other signals nearby - and will do it
as well as other transceivers priced in the $3K category.
