Split-Frequency Operation; Quick Split Operation - Yaesu FT-950 Operating Manual

RANSMITTER
A powerful capability of the FT-950 is its flexibility in Split Frequency operation using the VFO-A and VFO-B frequency
registers. This makes the FT-950 especially useful for high-level DX-peditions. The Split operation capability is very
advanced and easy to use.
1. Press the [ VFO-B ( RX )] Indicator/Switch, then rotate
the [ CLAR/VFO-B ] knob to set the desired VFO-B
frequency.
2. Press the [ VFO-A ( RX )] Indicator/Switch, then rotate
the Main Tuning Dial knob to set the desired VFO-A
frequency.
3. Now press the [ SPLIT ] button. The front panel Indi-
cator/Switch LEDs will look like this:
[ VFO-A ( RX )] Indicator/Switch: "ON" (LED glows Green)
[ VFO-A ( TX )] Indicator/Switch: "OFF" (LED Off)
[ VFO-B ( RX )] Indicator/Switch: "OFF" (LED Off)
[ VFO-B ( TX )] Indicator/Switch: "ON" (LED glows Red)

[ TXW ] Button
During Split operation, the VFO-A register will be used
for reception, while the VFO-B register will be used for
transmission. If you press the [ SPLIT ] button once more,
Split operation will be cancelled.
You may also press the [ VFO-A ( TX )] Indicator/Switch to
return transmit frequency control to the VFO-A register,
thereby canceling Split operation.

During normal (non-split) VFO-A operation, you may
simply press the [ VFO-B ( TX )] Indicator/Switch (lo-
cated on the upper right of the [ CLAR/VFO-B ] knob)
to engage Split operation. The [ VFO-B ( TX )] Indica-
tor/Switch will glow Red when you press the [ VFO-
B ( TX )] Indicator/Switch.
During Split operation, pressing the [ A B ] button will
reverse the contents of the VFO-A and VFO-B. Press
the [ A B ] button once more to return to the original
frequency alignment.
During Split operation you may listen to the TX fre-
quency temporarily while pressing the [ TXW ] button
located on the bottom left of the Main Tuning Dial
knob.
It is possible to set different operating modes (for ex-
ample, LSB and USB) on the two VFOs used during
Split operation.
During Split operation it is also possible to set the VFO-
A and VFO-B to different Amateur bands if you use a
multi band antenna.

Quick Split Operation

The Quick Split feature allows you to set a one-touch off-
set of +5 kHz to be applied to your radio's VFO-B (trans-
mit) frequency, compared to the VFO-A frequency.
1. Start with regular transceiver operation on the VFO-
A.
[ VFO-A ( RX )] Indicator/Switch: "ON" (LED glows Green)
[ VFO-A ( TX )] Indicator/Switch: "ON" (LED glows Red)
[ VFO-B ( RX )] Indicator/Switch: "OFF" (LED Off)
[ VFO-B ( TX )] Indicator/Switch: "OFF" (LED Off)
2. Press and hold in the [ SPLIT ] button for one second
to engage the Quick Split feature, and apply a frequency
5 kHz above the VFO-A frequency to the VFO-B fre-
quency register. Press and hold in the [ SPLIT ] button
for two seconds to increment the VFO-A frequency to
+5 kHz.
The VFO configuration will then be:
[ VFO-A ( RX )] Indicator/Switch: "ON" (LED glows Green)
[ VFO-A ( TX )] Indicator/Switch: "OFF" (LED Off)
[ VFO-B ( RX )] Indicator/Switch: "OFF" (LED Off)
[ VFO-B ( TX )] Indicator/Switch: "ON" (LED glows Red)

The operating mode applied to the VFO-B register will
be the same as that in use on the VFO-A register.
The offset of VFO-B from the VFO-A is programmed
via the Menu and is set to +5 kHz at the factory. How-
ever, other offsets may be selected using the following
procedure:
1. Press the [ MENU ] button to engage the Menu mode.
