Clar (Clarifier) Operation On Main (Vfo-A) - Yaesu FT DX 9000 CONTEST Operation Manual

CLAR ( C
The [ CLAR ] button and [ CLAR/VFO-B ] knob are used to offset either the receive, transmit, or both frequencies from
their settings on the VFO-A frequency (the Clarifier does not affect the , however). The four small numbers on the Multi
Display Window show the current Clarifier offset. The Clarifier controls on the FT
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.
TX CLAR
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 89 for details.
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
configured at the factory. If you wish to change this, so that the Clarifier Offset is also displayed on CW, use the
following procedure:
1. Press the [ MNU ] key to enter the Menu mode.
2. Rotate the [ Main Tuning Dial ] knob to select Menu item
"DISPLAY 016 BAR DISPLAY SELECT."
3. Rotate the [ CLAR/VFO-B ] knob to select "CLAR" (replac-
ing the default "CW-TUNE" selection).
4. Press and hold in the [ MNU ] key for two seconds to save
the new setting and exit to normal operation.

[ CLAR/VFO-B ] Knob [ B.MODE CLEAR ] Switch
Turning the Clarifier Off simply cancels the appli-
cation of the programmed offset from the receive
and/or transmit frequencies. To clear out the pro-
grammed Clarifier offset altogether, and reset it to
"zero," press the [ B.MODE CLEAR ] switch. The
programmed offset is displayed in the small multi-
channel window of the frequency display.
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.
