Clar (Clarifier) Operation On Main (Vfo-A) - Yaesu FTDX9000MP 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 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
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, and "CLAR" will appear on the
display 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, "RX"
will appear, and the programmed offset will be ap-
plied 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.

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 103 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 SE-
LECT."
3. Rotate the [ CLAR/VFO-B ] knob to select "CLAR"
(replacing 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.

Turning the Clarifier Off simply cancels the applica-
tion of the programmed offset from the receive and/
or transmit frequencies. To clear out the programmed
Clarifier offsert altogether, and reset it to "zero," press
the [ B.MODE/CLEAR ] switch. The programmed
offset is displayed in the small multi-channel win-
dow of the frequency display.

If the Clarifier seems not to be operating, check to
see if the Umber 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.
