This switch stores
the
displayed operating
frequency
and
mode
information in
the memory
channel
indicated on
the
frequency
display.
Memory
writing
is
possible
in either
the
VFO or
MEMORY
CHANNEL
mode. Refer to
SECTION
8
-
2
for
information
on
pro-
gramming the
memory
channels.
This
switch
operates
differently
depending
on
which
mode
the
IC-751 A is
in.
•
In
the
VFO
mode, the
frequency and
mode
stored
in the
memory
channel
displayed
transfer
to
the
selected
VFO.
•
In
the
MEMORY
CHANNEL
mode, the
displayed
frequency
and
mode
transfer to
the
VFO
used
immediately
prior to
changing
to
the
MEMORY
CHANNEL
mode.
NOTE: When
in
the
MEMORY
CHANNEL
mode,
it is
the
displayed
frequency
which
transfers to
the
VFO.
This is
not
necessarily
the
MEMORY
CHANNEL
frequency
since
the
TUNING
CONTROL
and
DFS
SWITCH
may
have been
used to
shift
the
operating
frequency.
Infor-
mation
stored
in
the
memory
channel
remains
un-
changed
after using
the
M
VFO
function.
