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. The [ CLAR/VFO-B ] knob
will now be enabled for offset tuning of the transmit-
ter.

Please verify that the lamp to the right of the [ CLAR/
VFO-B ] knob is not lit up in Orange. If so, this indi-
cates that this knob is currently engaged for Sub (VFO-
B) band tuning. If the Orange 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
"CLAR" and "TX" notation will appear on the fre-
quency display.
3. Rotate the [ CLAR/VFO-B ] switch 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; the Menu list will appear on the TFT.
2. Rotate the [ Main Tuning Dial ] knob to select Menu item
"DISPLAY 016 BAR DISPLAY SELECT."
3. Rotate the [ CLAR/VFO-B ] control 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 [ 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 frequency), you may then
press the [ RX ] switch 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 fre-
quency 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 off-
set, press the [ CLAR ] switch.
