■VFO description

VFO is an abbreviation of Variable Frequency Oscilla- tor, and traditionally refers to an oscillator.

The IC-7000 VFO is somewhat different. The VFO dis- play of the IC-7000 acts like a computer’s window and can show one frequency and one operating mode.

You can call up a desired frequency to the VFO with the memo pad-read key (p. 112) or the memory trans-

fer function (p. 109). You can also change the fre- quency with [DIAL] and select an operating mode with [MODE] key or call up previously accessed frequency

and modes with the band stacking register (p. 28).

The IC-7000 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 fre- quency and operating mode for operation.

DDifferences 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 oper- ating mode.

When VFO settings are changed with frequency and mode from another VFO or memory mode, the last- used frequency and operating mode for that VFO ap- pear.

[EXAMPLE]

VFO is selected.

The frequency is changed.

Memory mode is selected.

VFO is selected again.

Changed frequency (14.123 MHz) appears.

MEMORY MODE (pgs. 102–110)

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 changed with frquency and mode from another memory channel or VFO mode, the memorized frequency and operating mode appear.

[EXAMPLE]

Memory channel 1 is selected.

The frequency is changed.

Another memory channel is selected.

Memory channel 1 is selected again.

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