ONVENIENT RANSMITTER
A powerful capability of the FT
(VFO-B) frequency registers. This makes the FT
operation capability is very advanced and easy to use.
1. Set the Main (VFO-A) frequency as desired.
2. Set the Sub (VFO-B) frequency.
3. Now press the [ SPLIT ] switch. The "Split" mode will
be engaged, and the front panel switch/LEDs will look
like this:
MAIN(VFO-A)
[ RX ] switch "ON" (LED glows Green)
[ TX ] switch "OFF" (LED Off)
SUB(VFO-B)
[ RX ] switch "OFF" (LED Off)
[ TX ] switch "ON"(LED glows Red)
During Split operation, the Main (VFO-A) register will
be used for reception, while the Sub (VFO-B) register will
be used for transmission. If you press the [ SPLIT ] switch
once more, Split operation will be cancelled.
You may also press the [ TX ] switch located above and to
the left of the [ Main Tuning Dial ] knob to return trans-
mit frequency control to the Main (VFO-A) side, and
thereby cancel Split operation.

During normal (non-split) VFO-A operation,
you may simply press the Sub (VFO-B) [ TX ]
switch (located above and to the right of the
[ CLAR/VFO-B ] knob: to engage Split opera-
tion. The [ TX ] indicator will glow Red when
you press the switch.
During Split operation, pressing the [ A
switch will reverse the contents of the Main and
Sub VFOs. Press the [ A B ] switch once more
to return to the original frequency alignment.
During Split operation, if you press the [ RX ]
switch above and to the right of the [ CLAR/
VFO-B ] knob, you will engage Dual Receive
operation, and now can listen to both sides of
the DX pile-up, while transmitting on the Sub
(VFO-B) frequency. This is very useful for
maintaining the timing of your calls, while also
monitoring both sides of the pile-up.
During Split operation, you may also press the
[ TXW ] switch (below and to the left of the Main
Tuning Dial) to listen to the TX frequency tem-
porarily.
It is possible to set different operating modes
(for example, LSB and USB) on the two VFOs
used during Split operation.
During Split operation, it also is possible to set
the Main and Sub VFOs to different Amateur
bands, and it also is possible to engage
Crossband Full Duplex operation for multiplier
hunting while calling CQ on the "TX" band.
See page 105 for a discussion of full duplex
operation.
