VFO A
The
IC-751A contains two VFOs
for
receiving
and
transmitting.
Push
the A/B SWITCH
to select
VFO
A
or VFO
B
alternately
when
in the
VFO
mode.
This dual VFO
system provides
a great deal
of
operating flexibility.
•
When
VFO
A is
selected, "VFO
A" lights on the
display
and
both
transmit and receive
frequencies
are
as
indicated
on the
frequency
display.
This
frequency
and
the mode are
stored
in the VFO A
memory.
•
When VFO
B
is selected,
"VFO B"
lights on the
display and both
transmit
and
receive
frequencies
are
as
indicated
on the frequency
display.
This frequency
and
the
rhode are
stored in the VFO
B
memory.
1)
Select
the frequency
14.230.0MHz
and
USB using VFO A. Push
the VFO
A/B
SWITCH,
and the
display shows
the frequency
and
mode that
is stored
in
VFO
B. The frequency
14.230.0MHz
and
USB are
still stored in VFO
A, however.
2)
Push
the VFO
A/B SWITCH
again and the
display shows
the VFO
A
information.
Each time
the
switch
is pushed, the
alternate
VFO
is selected.
Switching from
one VFO
to the
other
VFO
does
not clear the
VFO
memories.
Push
the
VFO/MEMORY
[VFO/M]
SWITCH
to change
the
IC-751
A from
the VFO
mode
to the MEMORY
CHANNEL
mode or
vice
versa.
When
in the MEMORY
CHANNEL
mode,
any of
the
frequencies
stored
in the
32 memory
channels
may be selected
and
used.
