A powerful capability of the FT
DX
5000 is its flexibility in Split Frequency operation, using the Main (VFO-A) and Sub
(VFO-B) frequency registers. This makes the
FT
DX
5000
especially useful for high-level DX-pedition use, as the Split
operation capability is very advanced and easy to use.

ˆ During Split operation, if you press the (

button above and to the right of the [ CLAR

knob, you will engage Dual Receive operation. Now
you can listen to both sides of the DX pile-up, and
transmit on the VFO-B frequency. This is very useful
to determine the timing of your calls, while also moni-
toring both sides of the pile-up.
ˆ During Split operation, you may also listen to the TX
frequency temporarily, by pressing the [
TXW
] button
(just below the [ SPLIT

ˆ It is possible to set different operating modes (for ex-
ample, LSB and USB) on the two VFOs used during
Split operation.
ˆ During Split operation, it is also possible to set VFO-
A and VFO-B to different amateur bands. But, remem-
ber that Dual Reception must be within the same band.
VFO Tracking Feature
In the default setting, the VFO-A frequency and VFO-B
frequency are changed individually using the Main Tun-
ing Dial knob and the [
CLAR
(
VFO-B

If you want to tune the VFO-A frequency and VFO-B fre-
quency together, the VFO Tracking feature is very useful.
Here is the procedure for activating the VFO Tracking fea-
ture:
1. Press the [ MENU
