For split TX/RX operation in "casual" pile-ups, where the split is less than 10 kHz, the TX Clarifier (Offset Tuning) fea-
ture may be utilized.
1. Press the [ TX CLAR ] button. The "TX" icon will
appear in the TFT display.

The Clarifier is frequently used for receiver offset
tuning. However, for DX pile-ups where the DX
station is using a split of less than 10 kHz, the TX
Clarifier function is usually the quickest way to set
the transmitter to the desired offset frequency.
2. Rotate the [ VFO-B/CLAR ] knob to set the desired
transmitter offset. A maximum split of ±9.999 kHz
may be set.
3. To exit from TX Clarifier operation, press the [ TX
CLAR ] button once more. The "TX" icon will disap-
pear from the display.

 When listening to a "pile-up" calling a DX station,
in order to find the station currently being worked,
you may press the [ RX CLAR ] button. Then, use
the [ VFO-B/CLAR ] knob to zero in on the station
calling the DX (use the SPOT function on CW for
precise alignment of your frequency). You may then
press the [ RX CLAR ] button again to cancel the RX
Clarifier, and return to reception on the DX station's
frequency.
 Just as with receiver Clarifier operation, the amount
of offset from the original VFO frequency will ap-
pear in the display.
 As with receiver Clarifier operation, when you turn
the TX Clarifier off, the last-used offset is remem-
bered, and will be available if you turn the TX Clari-
fier back on. To clear the Clarifier offset, press the
[ CLEAR ] button.

A visual depiction of the relative offset of the Clarifier may be displayed, using the Tuning Offset Indicator.
1. Press the [ MENU ] button to engage the Menu
mode.
2. Rotate the [ VFO-B/CLAR ] knob (or press the
 / button) to select Menu item "011 BAR
DISPLAY SELECT".
3. Press the [SELECT] button, then rotate the
[ VFO-B/CLAR ] knob (or press the / button)
to select "CLAR" from the available choices; the
factory default is "CW TUNE".
4. Press the [ SELECT ] button, then press the
[ MENU ] button to save the new setting and exit
to normal operation.

When attempting to work a DX station on CW in a split
frequency pile-up, remember that a large number of
other stations may also be using Yaesu transceivers with
capability similar to that of your FT
side of the pile-up, everyone calling precisely on the
same CW frequency will sound like a single tone! So
you may have more success if you use the RX Clarifier
to find a hole in the pile-up, instead of trying to zero-
beat the last station worked by the DX station.
