The "D" includes:
TCXO-1 High Stability Oscillator
(+/- 0.5 ppm vs. standard +/- 2.0 ppm)
BPF-1 Second Receiver Bandpass Filter Unit
(allows true dual receive on separate bands)
XF-455K-262-01 (2.6 KHz) "XF-C"
(third IF - replaces muRata CFJ455K-15 "XF-G")
XF-455K-501-03 (500 Hz) "XF-E" or YF-110C
(third IF - "normal" CW)
XF-455K-202-01 (2.0 KHz) "XF-D" or YF-110SN
(third IF - "narrow" SSB)
The following filters are optional in both FT-1000 and "D"
XF-455K-251-01 (250 Hz) "XF-F" or YF-110CN
(third IF - "narrow" CW)
XF-455MC (600 Hz)
(sub-receiver CW)

Without modification, the "D" cascades the 2.6 KHz SSB third
IF filter with the 250 Hz second IF filter.

You would want an FT-1000 produced in series 10 or later.
The appropriate serial numbers would be xx10000 or higher
(unless the radio has been updated by the factory).
