Clar (Clarifier) Operation - Yaesu FT-950 Operating Manual

B
ASIC
The [ TX CLAR ] , [ RX CLAR ] , [ CLEAR ] buttons and [ CLAR/VFO-B ] knob are used to offset the receive frequency, the
transmit frequency, or both, from their settings on the VFO-A frequency (the Clarifier does not affect VFO-B). Four small
numbers on the Multi-Display Window show the current Clarifier offset. The Clarifier controls on the FT-950 are designed
to allow you to preset an offset (up to ±9.990 kHz) without actually retuning, and then to activate it via the Clarifier's [ RX
CLAR ] and [ TX CLAR ] buttons. This feature is ideal for following a drifting station, or for setting small frequency offsets
sometimes utilized in DX "Split" work.
Here is the technique for utilizing the Clarifier:
1. Press the [ RX CLAR ] button. In the Multi-Display
Window, the "RX" notation will ap-
pear, and the programmed offset will
be applied to the receive frequency.
2. Rotation of the [ CLAR/VFO-B ] knob will allow you
to modify your initial offset on the fly. Offsets of up to
±9.990 kHz may be set using the Clarifier.
To cancel Clarifier operation, press the [ RX CLAR ] but-
ton. The "RX" notation will disappear from the display.

Turning the Clarifier off simply cancels the applica-
tion of the programmed offset from the receive and/or
the transmit frequencies. To clear the Clarifier offset,
and reset it to "zero," press the [ CLEAR ] button. The
programmed offset is displayed in
the small multi-channel window of
the frequency display.
You may also activate the clarifier on the VFO-B fre-
quency. In this case, the offset frequency is set using
the Main Tuning Dial knob, instead of the [ CLAR/
VFO-B ] knob (VFO-B operation is discussed on page
35).
The Clarifier operation (including the offset frequency)
will be memorized independently on each VFO stack
of VFO-A and VFO-B.
The Tuning Offset Indicator provides a graphical representation of the Clarifier offset.
In the factory default setting On CW, the Tuning Offset Indicator is used for CW Center
Tuning, instead of Clarifier Offset. If you wish to change this so that the Clarifier Offset
is also displayed on CW, use the following procedure:
1. Press the [ MENU ] button to enter the Menu mode.
2. Rotate the [ SELECT ] knob to select Menu item
"006 DISP BAR SEL

3. Rotate the [ CLAR/VFO-B ] knob to select "CLAr

4. Press and hold in the [ MENU ] button for one sec-
ond to save the new setting and exit to normal op-
eration.

Alternately, You may apply the Clarifier offset to
the transmit frequency, without changing the receive
frequency (typically, for "split" DX pile-ups). See
