The CLAR button and CLAR/VFO-B knob are used to offset either the receive, transmit, or both frequencies from
their settings on the main band (VFO-A) frequency (the Clarifier does not affect the sub band (VFO-B), however). The four
small numbers on the Multi Display Window show the current Clarifier offset. The Clarifier controls on the FT
DX
9000 are
designed to allow you to preset an offset (up to ± 9.999 kHz) without actually retuning, and then to activate it via the
Clarifier’s RX (FAST RX) and TX (BAND/MHz TX) buttons. This feature is ideal for following a drifting station, or for
setting small frequency offsets sometimes utilized in DX “Split” work.
Here is the technique for utilizing the Clarifier:
1. Press the CLAR switch (# ). The LED imbedded
in the switch will glow Red to signify that rotation of
the CLAR/VFO-B knob (#
) will allow setting of
a frequency offset.
2. Press the FAST/RX switch (# ). On the display,
“CLAR” and “RX” will appear, and the programmed
offset will be applied to the receive frequency.
3. Rotation of the CLAR/VFO-B knob will allow you
to modify your initial offset on the fly. Offsets of up to
± 9.99 kHz may be set using the Clarifier.
To cancel the application of the offset to the receiver fre-
quency temporarily, press the FAST/RX switch. The
“CLAR RX” notation will disappear from the display.
To cancel Clarifier operation, press the CLAR switch.
TXCLAR
Without changing the receive frequency, you may
alternatively apply the Clarifier offset to the trans-
mit frequency (typically, for “split” DX pile-ups).
See page 95 for details.
Advice
Turning the Clarifier Off simply cancels the application of
the programmed offset from the receive and/or transmit
frequencies. To clear out the programmed Clarifier offset
altogether, and reset it to “zero,” press the CLAR switch
(#
). The programmed offset is displayed in the small
multi-channel window of the frequency display.
Note
If the Clarifier seems not to be operating, check to see if
the Orange lamp to the right of the CLAR/VFO-B knob
(#
) is illuminated. If so, pressing the A/B switch
(# ) will cause the Orange lamp to the right of the
CLAR/VFO-B knob to go out. Now press the CLAR
switch (# ) to begin Clarifier operation.
The LED Bar Display provides a graphical representation of the Clarifier offset.
On CW, the Bar Display field is used for CW Center Tuning, instead of Clarifier Offset, as the transceiver is config-
ured at the factory. If you wish to change this, so that the Clarifier Offset is also displayed on CW, use the following
procedure:
CLAR key
CLEAR key
CLAR/VFO-B knob
RX key
1. Press the MNU key (# ) to enter the Menu
mode.
2. Rotate the Main Tuning Dial to select Menu item
“DISPLAY 016 BAR DISPLAY SELECT.”
3. Rotate the CLAR/VFO-B knob (# ) to select
“CLAR” (replacing the default “CW-TUNE” se-
lection).
4. Press and hold in the MNU key for two seconds to
save the new setting and exit to normal operation.

(TX frequency = RX frequency)
