BASIC OPERATION

■VFO description 

VFO is an abbreviation of Variable Frequency Oscilla-
tor, and traditionally refers to an oscillator. The IC-703’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. 60) or with the memory
transfer switch (p. 58). You can also change the fre-
quency with the main dial and select an operating
mode with the [MODE] switch or call up previously ac-
cessed frequency and modes with the band stacking
register (p. 22).

The IC-703 has two VFOs, specially suited for split fre-
quency operation. The VFOs are called VFO A and
VFO B. You can use the desired VFO to call up a fre-
quency and operating mode for operation.

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 oper-
ating mode.

When the VFO is selected from another VFO or
memory mode, the last-used frequency and operat-
ing mode for that VFO appear.

MEMORY MODE (pgs. 56–60)
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 operating mode.

When a memory channel is selected from another
memory channel or VFO mode, the memorized fre-
quency and operating mode appear.

VFO is selected.

The frequency is changed.

VFO is selected again.

Changed frequency (14.123 MHz) appears.

Changed frequency (14.123 MHz) does not appear and 
memorised frequency (14.100 MHz) appears instead.

Memory mode is selected.

Memory channel 1 is
selected.

The frequency is changed.

Memory channel 1 is
selected again.

Another memory channel
is selected.
