The FT-847 provides convenient split-frequency operation, using the Main and Sub VFOs, for DX working and
other operating situations requiring unique split frequency pairs. For repeater operation using the default shifts
provided, see page 52. Split operation per this section is not a “full-duplex” configuration as needed for satellite
operation; see page 66 for details regarding satellite full-duplex operation.
The example below will describe a split-frequency DX situation on the 20-meter band, with a DX station transmit-
ting on 14.025 MHz, listening 10 kHz higher in the band.
•
With the Main VFO set to 14.025.00 MHz CW,
press the [
A
u
B
] key to transfer the contents of the
Main VFO into the Sub VFO.
‚
Press the [
SPLIT
] key momentarily. The FT-847
will now transmit using the Sub VFO frequency,
and will receive using the Main VFO frequency.
The “
SPLIT
” icon will appear on the display.
ƒ
Rotate the
SUB-TUNE
knob to set 14.035.00 MHz
on the Sub VFO display.
„
To listen to the pile-up calling the DX station (so
as to align your frequency more closely to that of
the station being worked by the DX), press the
[
A
u
t
B
] key. The Main VFO will now be tuning in
the vicinity of 14.035 MHz, and you can zero in on
the DX station’s listening frequency by tuning in
on the station in QSO with the DX. Press [
A
u
t
B
]
again to return the receiver to the DX station’s trans-
mitting frequency.
…
Press the [
SPLIT
] key once more to cancel split
operation. Transmit/receive control will revert to
the Main VFO, and the “
SPLIT
” icon will disap-
pear from the display.
