PLIT PERATION
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 [ CLAR ] switch. The Red LED imbedded in
the switch will light up, and "CLAR" will appear in
the Multi Panel Window on the Frequncy Display. The
[ CLAR/VFO-B ] knob will now be enabled for offset
tuning of the transmitter.

Please verify that the lamp to the right of the [ CLAR/
VFO-B ] knob is not lit up in Umber. If so, this indi-
cates that this knob is currently engaged for Sub band
(VFO-B) tuning. If the Umber lamp is lit, press the
[ A/B ] switch, then press the [ CLAR ] switch, to en-
gage Clarifier operation.

The Clarifier is frequently used for receiver offset tun-
ing. 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 trans-
mitter to the desired offset frequency.
2. Press the [ BAND/MHz TX ] switch, located above and
to the right of the [ CLAR/VFO-B ] knob. The "TX"
notation will appear in the Multi Panel Window on
the Frequncy Display.
3. Rotate the [ CLAR/VFO-B ] knob to set the desired
transmitter offset. A maximum split of ± 9.99 kHz may
be set.
A visual depiction of the relative offset of the Clarifier may be displayed, using the Bar Indicator.
1. Press the [ MNU ] key momentarily. The Menu list will
appear on the LCD display.
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"
form the available choices; the factory default is "CW-
TUNE."
4. Press and hold in the [ MNU ] key for two seconds to
save the new setting and exit to normal operation.

To listen to the pile-up calling the DX station, so as to
find the station currently being worked, you may press
the Sub (VFO-B) band's [ RX ] switch (above and to
the left of the [ CLAR/VFO-B ] knob). Once you have
zeroed in on the station calling the DX (use the SPOT
function on CW for precise alignment of your fre-
quency), you may then press the Sub (VFO-B) band's
[ RX ] switch again to cancel the RX Clarifier, and re-
turn to reception 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 Multi Panel window on the Frequncy Display.
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, press the
[ CLAR ] switch.
