Split Operation Using The Tx Clarifier - Yaesu FT-950 Operating Manual

T
RANSMITTER
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 ] button. The "TX" icon will ap-
pear in the Multi-Display Window
in the display.

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 func-
tion is usually the quickest way to set the transmitter to
the desired offset frequency.
2. Rotate the [ CLAR/VFO-B ] knob to set the desired
transmitter offset. A maximum split of ±9.99 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 Multi-Display Window.

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
[ CLAR/VFO-B ] 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 appear in
the small display window.
As with receiver Clarifier operation, when you turn the
TX Clarifier off the last-used offset is remembered,
and will be available if you turn the TX Clarifier 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 Bar
Indicator.
1. Press the [ MENU ] button to engage the Menu
mode.
2. Rotate the [ SELECT ] knob to select Menu item
"006 DISP BAR SEL
006 DISP BAR SEL 006 DISP BAR SEL

ond to save the new setting and exit to normal op-
eration.

When you operate on the VFO-B frequency, you may
also activate the Clarifier on the VFO-B frequency.
However, the offset frequency is set using the Main
Tuning Dial knob, instead of the [ CLAR/VFO-B ]
knob.
The Clarifier operation (including the offset frequency)
will be memorized independently on each VFO stack
of the VFO-A and VFO-B.

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-
bility similar to that of your FT-950. On the DX 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.
