A powerful capability of the FT
DX
9000D is its flexibility in Split Frequency operation, using the Main (VFO-A) and Sub
(VFO-B) frequency registers. This makes the FT
DX
9000D especially useful for high-level DX-pedition use, as the Split
operation capability is very advanced and easy to use.
1. Set the Main (VFO-A) frequency as desired.
2. Set the Sub (VFO-B) frequency.
3. Now press the SPLIT switch (# ). The “Split”
mode will be engaged, and the front panel switch/LEDs
will look like this:
MAIN(VFO-A)
RX switch (# ) “ON” (LED glows Green)
TX switch (# ) “OFF” (LED Off)
SUB(VFO-B)
RX switch (# ) “OFF” (LED Off)
TX switch (# ) “ON”(LED glows Red)
During Split operation, the Main (VFO-A) register will be
used for reception, while the Sub (VFO-B) register will be
used for transmission. If you press the SPLIT switch
once more, Split operation will be cancelled.
You may also press the TX switch located above and to
the left of the Main tuning Dial to return transmit frequency
control to the Main (VFO-A) side, and thereby cancel Split
operation.
Advice
During normal (non-split) VFO-A operation, you may
simply press the Sub (VFO-B) TX switch (located
above and to the right of the CLAR/VFO-B knob:
#
) to engage Split operation. The TX indicator
will glow Red when you press the switch.
During Split operation, pressing the A B switch
(# ) will reverse the contents of the Main and Sub
VFOs. Press the A B switch once more to return
to the original frequency alignment.
During Split operation, if you press the RX switch
above and to the right of the CLAR/VFO-B knob,
you will engage Dual Receive operation, and now can
listen to both sides of the DX pile-up, while transmit-
ting on the Sub (VFO-B) frequency. This is very use-
ful for maintaining the timing of your calls, while also
monitoring both sides of the pile-up.
During Split operation, you may also press the TXW
switch (#
; below and to the left of the Main Tuning
Dial) to listen to the TX frequency temporarily.
It is possible to set different operating modes (for ex-
ample, LSB and USB) on the two VFOs used during
Split operation.
During Split operation, it also is possible to set the
Main and Sub VFOs to different Amateur bands, and
it also is possible to engage Crossband Full Duplex
operation for multiplier hunting while calling CQ on
the “TX” band. See page 98 for a discussion of full
duplex operation.
