Vfo Description - Icom IC-756PRO Instruction Manual

VFO description

VFO is an abbreviation of Variable Frequency Oscilla-
tor, and traditionally refers to an oscillator.
The transceiver's VFO is somewhat different. The VFO
of the IC-756PRO 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 keypad, memo pad-read switch (see p. 55) or the
memory transfer function (see p. 53). You can also
change the frequency with the tuning dial and select
the operating mode with the mode switches.
During dualwatch or split frequency operation, the sub
VFO is functional (non-outline, non-spotted, larger fre-
quency characters). While pushing [XFC] during split
frequency operation, you can change the transmit
readout frequency with the keypad, memo pad-read
switch or the memory transfer function.
• Differences between VFO mode and memory mode
VFO MODE
VFO shows a frequency and operating mode. If the
frequency or operating mode is changed, the VFO au-
tomatically memorizes the new frequency or new op-
erating mode.
When a VFO is selected from another band or mem-
ory mode, the frequency and operating mode last
used for that VFO appear.
[EXAMPLE]
VFO is selected.

Memory mode is selected.
wq≥puy≥tp
VFO is selected again.
qr≥qwe≥pp
Changed frequency (14.123 MHz) appears.

MEMORY MODE (pgs. 50–54)
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 the memory channel is selected from another
memory channel or VFO mode, the memorized fre-
quency 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.
