A powerful capability of the FT-2000D is its flexibility in Split Frequency operation, using the Main (VFO-A) and Sub
(VFO-B) frequency registers. This makes the
FT-2000D
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
] button. 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)
[

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
] button
once more, Split operation will be cancelled.
You may also press the Main [ TX

and to the right of the Main Tuning Dial knob to return
transmit frequency control to the Main (VFO-A) side,
thereby cancelling Split operation.

ˆ 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 [
SUB VFO-B

frequency alignment.
ˆ During Split operation, if you press the [ RX

above and to the right of the [ SUB VFO-B
] knob, you
will engage Dual Receive operation, and now can lis-
ten to both sides of the DX pile-up, while transmitting
on the Sub (VFO-B) frequency. This is very useful for
maintaining the timing of your calls, while also moni-
toring both sides of the pile-up.
ˆ During Split operation, you may also listen the TX fre-
quency temporarily while pressing the [
TXW
] button
(below and to the left of the Main Tuning Dial knob).
ˆ It is possible to set different operating modes (for ex-
ample, LSB and USB) on the two VFOs used during
Split operation.
ˆ During Split operation, it also is possible to set the
Main and Sub VFOs to different Amateur bands. But
remember that Dual Reception must be within the same
band.
