In case it isn't obvious what has changed, note the TS-590 entry
(ninth entry in the table).

Actually there are two entries in the table, one for 20 meters and one
for 17 meters. Rob needed to do this because the TS590 uses down-
conversion (higher performance) on about half the bands, and up-
conversion on the others, including the WARC bands.

There are question marks entered for a couple of the measurements on
17 m. I won't speculate; perhaps Rob can give us an explanation.

The question mark is foot-noted -- in the ninth column, the measurement is
phase-noise limited.

Hi Ed

It will be interesting to see where the FT2000 places with the new
AC0C Network Sciences filter. This radio with the new filter might be bargain if it does perform well. I dont know if Sherwood will be testing
this new filter radio combination.

I wonder how such a high performance filter would work in the K3? Not that its needed in the K3. However in the interest of science, it might be a worthy pursuit. It also might push the K3 well ahead of the FT5000 in ultimate performance.

PA3AKE in his H mode mixer work has already proven that high performance roofing filters can make a substantial difference towards achieving ultimate receiver performance.
