FREQUENCY SETTING
■ VFO description
VFO is an abbreviation of Variable Frequency
Oscillator, and traditionally refers to an oscillator. The
IC-706MKIIG’s VFO can store a frequency and an
operating mode.
You can call up a desired frequency to a VFO with the
memo pad-read switch (p. 42) or with the memory
transfer switch (p. 42). You can also change the fre-
quency with the main dial and select an operating
mode with the [MODE] switch or call up previously
accessed frequency and modes with the band stack-
ing register (p. 19).
The IC-706MKIIG has two VFOs, specially suited for
split frequency operation. The VFOs are called VFO A
and VFO B. You can use the desired VFO to call up a
frequency and operating mode for operation.

• The differences between VFO and memory mode
VFO MODE
Each VFO shows a frequency and operating mode. If
the frequency or operating mode is changed, the
VFO automatically memorizes the new frequency or
operating mode.
When the VFO is selected from another VFO or
memory mode, the last-used frequency and operat-
ing mode for that VFO appear.
[EXAMPLE]
MEMORY MODE (pgs. 39–42)
Each memory channel shows a frequency and oper-
ating mode like a VFO. Even if the frequency or
mode is changed, the memory channel does not
memorize the new frequency or memory mode.
When a memory channel is selected from another
memory channel or VFO mode, the memorized fre-
quency and operating mode appear.
