■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

• 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.

	CH

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.

USB	Memory channel 1 is
	selected.

USB	The frequency is changed.
