FREQUENCY SETTINGS
 VFO description
VFO is an abbreviation of Variable Frequency Oscilla-
tor, and traditionally refers to an oscillator.
The IC-718 VFOs can store frequencies and operat-
ing modes
You can set a desired frequency in the VFO with the
[MAIN DIAL], the keypad or the Memory Copy function.
(p. 37) You can also select the operating mode with the
[MODE] switch or call up previously accessed frequen-
cies and modes with the Band Stacking Register. (p.
18)
The IC-718 has two VFOs, VFO A and VFO B, es-
pecially suited for split frequency operation. You can
easily use an operating frequency.
• Differences between the VFO mode and the Memory mode
VFO MODE
Each VFO displays a frequency and operating mode.
If the frequency or mode is changed, the VFO auto-
matically memorizes the new frequency or mode.
When you select a VFO, the last used frequency and
mode appear, even if another frequency or mode is
selected in another VFO or Memory channel.
[EXAMPLE]
VFO is selected.
The frequency
is changed.
Memory mode
is selected.
VFO is selected
again.
Last used frequency (14.123 MHz) appears.

MEMORY MODE (pp. 35 –38)
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 mode.
When you select the Memory channel, the memorized
frequency and mode appear, even if the frequency or
mode is changed in the memory, then another mem-
ory or VFO is selected.
[EXAMPLE]
Memory channel 1
is selected.
The frequency
is changed.
Another Memory
channel is selected.
Memory channel 1
is selected again.
Memorized frequency (14.100 MHz) appears instead of
the changed frequency (14.123 MHz).
