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.
