A powerful capability of the
FT-450
is its flexibility in Split Frequency operation, using VFO-A and VFO-B fre-
quency registers. This makes the
FT-450
especially useful for high-level DX-pedition use, as the Split operation
capability is very advanced and easy to use.
1. Press the [
A/B
] button to switch the VFO register
to VFO-A, then set the transmit frequency.
2. Press the [
A/B
] button again to switch the VFO
register to VFO-B, then set the receive frequency.
3. Now press the [
STEP/SPLIT
] button to activate
Split-Frequency Operation.
4. The “
” icon will appear in the display.
5. To quit Split-Frequency Operation, press the
[
STEP/SPLIT
] button again.

transmit frequency compared to the receiving frequency. Furthermore, the transmit mode sets to the
same mode as the receiving frequency register.

STEP/SPLIT
] button
for one second to engage the Quick Split fea-
ture. The transmit mode is set to the same
mode as the receiver frequency register and
applies a frequency 5 kHz above the receiv-
ing frequency register to the transmit fre-
quency register.
The “
