I understand that Sherwood places a lot of emphasis on 2 kHz BDR.  While
that is a worthwhile measurement, I am concerned more about the Filter
Ultimate (dB) column.  Not only being 15 dB poorer than than the K3, note
also that the FT-5000 is phase limited in this regard.  It will take
someone more educated than I to tell us what that means in practical
terms, but it is one glaring difference between two radios that appear
to be almost identical.  Also, the FT-5000 being 13 dB poorer in the 100
kHz BDR column is also glaring and perhaps telling.

Given the recent discussion on the FT-5000's transmitted phase noise, it
would be nice to see if Bob could provide some independent testing of
transmitters as well.

At the end of the day it would appear that the Yaesu engineers have done
their homework in some areas but left room for improvement.

P.S.  My K3 is staying put.  :-)
