First-off my apology this reply is so behind in time. My main
computer was under re-build so was having to use web-based e-mail to

I think which parameter is most significant depends a lot on the use,

I doubt if I would be able to appreciate the difference between the
numbers of the top three ranked, but I'm no expert.
The Sherwood numbers are not a comprehensive description of
listenability. I am able to appreciate the recent improvements in K3
AGC and NR. But these improvements, it is said,
Gary,
One answer to your first question is that the results of IMDDR3 tests at 2
kHz spacing, performed with a 500 Hz IF filter inline, do not themselves
tell you how a receiver will cope with two or more close spaced and strong
signals inside its 500 Hz passband. In the case of a superhet,
Very well done indeed. But, I am confused. How is the ranking decided?
Is it subjective or is there a formula?

As it says at the top, the table is sorted by Dynamic Range Narrow Spaced.

It's ranked by Rob's narrow spaced dynamic range measurement.

*Barry,
Perhaps more to the point..How does the measurement from Sherwood relate to
real time performance and usability for the operator?
In what way does an operator detect a difference so small between say the
top 3 on the list?
Is the price differential worth buying say position one in the
Rob sorts the table based on IMDDR3 at a 2-kHz spacing. This is the
second-to-last column of the table.

In real world operating, it is an indicator of how much a signal 1 kHz
away will interfere with the desired signal you are trying to copy. The
greater the dynamic range, the stronger that undesired signal can be and
still allow you to copy.

I would love to see Rob do the K3 radio AGAIN with the latest goodies in it.
Notice that it shows as tested in 2008. I would suspect some things are
better than the 2008 setup.

Wayne,
Thanks for the summary. Actually, the column that makes the most sense and the
one that should rank first in ordering is the name of the company providing the
rig and Elecraft comes first in that ordering because of course it starts with
the letter E which is the most frequently
On behalf of the entire staff, I'll take this as a meta-compliment :)
