For split TX/RX operation in “casual” pile-ups, where the split is less than 10 kHz, the TX Clarifier (Offset Tuning) feature
may be utilized.
1. Press the [ TX CLAR/LOCK
] button briefly. The
“ ” and “ ” icon will appear in the display,
and the programmed offset will be
applied to the receive frequency.

:
If the “ ” and “ ” icon does not appear, check
to see if the LED imbedded in the [ A/B
] button glows
orange. If so, pressing the [ A/B
] button briefly, will
cause the [ A/B
] button to go out. Now, press the [
TX
CLAR/LOCK
] button briefly, to begin clarifier op-
eration.
2. Rotate the [ CLAR
(
VFO-B
)] 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/LOCK
] button once more. The “
” icon will
disappear from the display.

OINT
:
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 capa-
bilities similar to your
FT
DX
5000 . On the DX side of the
pile-up, everyone calling precisely on the same CW fre-
quency 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.
Clarifier Offset Bar Indicator
A visual depiction of the relative offset of the Clarifier may be displayed, using the Bar Indicator.
1. Press the [
MENU
] button briefly, to enter the Menu
mode.
2. Rotate the (
VFO-A
)[
SELECT
] knob to select
Menu item “
012 DISP BAR SEL
”.
3. Rotate the (
VFO-B
)[
SELECT
] knob to select
“
CLAR
(Clarifier)” (re-
placing the default “ CW
TUNE
(CW TUNING)”
selection).
4. Press and hold in the
[
MENU
] button for two
seconds to save the new
setting and exit to nor-
mal operation.
A
DVICE
:
The frequency step of the TX clarifier depends on the
Main Tuning Dial knob.
To listen to the pile-up calling the DX station, to find
the station currently being worked, you may press the
[
RX CLAR/FAST ] button. Once you have zeroed in
on the station calling the DX (use the SPOT function
on CW for precise alignment of your frequency), you
may then briefly press the [
RX CLAR/FAST
] button
again to cancel the RX Clarifier, and return to recep-
tion on the DX station’s frequency.
Just as with receiver clarifier operation, the amount of
offset from the original VFO frequency will appear in
the small display window.
As with receiver clarifier operation, when you turn the
TX clarifier off the last-used offset is not lost, and will
be available if you turn the TX Clarifier back on. To
clear the Clarifier offset, briefly press the [
CLEAR ]
button.
