In my measurements, the FT1000(D) and FT1000MP are virtually 
the same. I corrected the original FT1000MP measurements on my 
web page because the FT1000MP I tested had a 70MHz IF 
amplifier added.

This amplifier reduces close-spaced blocking and IMD dynamic 
range by approximately the gain of the amplifier, although it will not 
affect performance at spacings wider than a dozen kilohertz or so.
