Quick Split Operation; Direct Input Of Offset Frequency - Yaesu FTDX10 Operation Manual

SPLIT
A powerful capability of the FTDX10 is its flexibil-
ity in Split Frequency operation using the VFO-A
and VFO-B frequency registers. This makes the
FTDX10 especially useful for high-level DX-pedi-
tions. The Split operation capability is very ad-
vanced and easy to use.
1. Set the VFO-A frequency to the desired receive
frequency.
2. Press the [A/B] key.
3. Set the VFO-B frequency to the desired transmit
frequency.
4. Press the [A/B] key, then press the [SPLIT] key.
The LED indicators will appear as shown below:
Green
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] key
once more, Split operation will be cancelled.
● During Split operation, pressing the [A/B] key will
reverse the contents of VFO-A and VFO-B. Press
the [A/B] key once more to return to the original
frequency settings.
● The receive and transmit frequencies can be set
to different bands or operation modes.
● ● When transmitting and receiving with VFO-A,
if you press the [SPLIT] key, VFO-B will become
the transmit frequency and the VFO-B frequency
display will be red.
Press and hold the [SPLIT] key to increase the
VFO-B transmit frequency by 5kHz.

• Quick Split Operation

The Quick Split feature allows setting a one-touch
offset of +5kHz as compared to the VFO-A frequen-
cy, to be applied to the transceiver VFO-B (transmit)
frequency.
1. Start with regular transceiver operation on
VFO-A.
2. Press and hold the [SPLIT] key to engage the
Quick Split feature, which applies a frequency
5kHz above the VFO-A frequency to the VFO-B
frequency register.
3. Press and hold in the [SPLIT] key to increment
the VFO-B frequency another +5kHz.
● The offset of VFO-B from VFO-A is programmed
via the Menu and is set to +5kHz factory default.
● However, other offsets may be selected using
menu item [QUICK SPLIT FREQ] (page 100).

• Direct input of offset frequency

The offset can be set to a frequency other than
5kHz with the on-screen keyboard.
1. Set the VFO-A frequency to the desired
receive frequency.
2. Press the [FUNC] knob.
3. Select [OPERATION SETTING] → [GENERAL]
→ [QUICK SPLIT INPUT].
4. Select "ON".
5. Press the [FUNC] knob to save the new setting.
6. Touch [BACK] several times to return to normal
operation.
7. Press and hold the [SPLIT] key.
8. Enter the offset frequency with the keyboard on
the screen, then touch [kHz].
● The frequency range that can be input is from
-20kHz to +20kHz.
TXW
During a split operation, press and hold the TWX-
button to listen on the transmitter frequency while-
holding the button.
ZIN/SPOT
ZIN
Press the [ZIN/SPOT] switch momentarily to adjust
the receiving frequency and zero-in automatically
while receiving a CW signal.
SPOT
While pressing and holding [ZIN/SPOT], the tone is
output from the speaker. This tone corresponds to
the pitch of your transmitted signal. If you adjust the
receiver frequency until the pitch of the received
CW signal matches that of the Spot tone, the trans-
mitted signal will be precisely matched to that of the
other station.
LOCK
This key toggles the ON/OFF lock for the MAIN Dial
knob. When "Lock" is ON, the MAIN Dial knob can
still be turned, but the frequency will not change,
and "LOCK" appears in the frequency display.
