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 im-
bedded in the switch will light up. The CLAR/VFO-
B knob (#
) will now be enabled for offset tuning of
the transmitter.
Advice
H
Please verify that the lamp to the right of the CLAR/VFO-
B knob is not lit up in Orange. If so, this indicates 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 engage Clarifier operation.
Quick Point
H
The Clarifier is frequently used for receiver offset tuning. How-
ever, for DX pile-ups where the DX station is using a split of
less than 10 kHz, the TX Clarifier function is usually the quick-
est way to set the transmitter 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
frequency display.
3. Rotate the CLAR/VFO-B switch to set the desired
transmitter offset. A maximum split of ± 9.99 kHz may
be set.
To disengage the transmit Clarifier temporarily, press the
TX switch once more. The “CLAR TX” indication will
disappear from the frequency display area.
To exit from Clarifier operation, press the CLAR switch
once more. The “CLAR” indication will disappear from
the TFT.
Advice
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 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, press the CLAR switch.
