3 FREQUENCY SETTING
E VFO description
The transceiver has two VFOs for both bands, spe-
cially suited for instant selection of 2 frequencies or
split frequency operation. The VFOs are called VFO
A and VFO B. You can use a desired VFO to call up
a frequency and operating mode for your operation.
VFO is an abbreviation of Variable Frequency Oscil-
lator, and traditionally refers to an oscillator.
CONVENIENT
Use two VFOs as a quick memory
When you find a new station but you wish to continue
searching, the two VFO system can be used for quick
memory storage.
@ Push [FUNC] then [VFO*A=B] for 2 sec. to store the
displayed frequency into the undisplayed VFO.
@ Continue searching stations.
© Push [VFO] to retrieve the stored frequency.
@ To continue searching stations, push [VFO] again.

e The differences between VFO mode and memory mode
VFO MODE
Each VFO shows a frequency and operating mode.
lf the frequency or operating mode is changed, the
VFO automatically memorizes the new frequency or
new operating mode.
When a VFO is selected from another VFO or the
memory mode, the last used frequency and oper-
ating mode for that VFO appear.
[EXAMPLE]
[A-B] ,
VFO A is selected.
The frequency is changed.
A=B) ,
VFO B is selected.
[A=B]
VFO A is selected again.
Changed frequency (145.875 MHz) appears.
MEMORY MODE (pgs. 33-35)
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]
M> VEO)
Memory channel 1 is selected.
The frequency is changed.
[Xe] Another memory channel is
Ca) selected.
GAJ Memory channel 1 is selected
CY) again.
Changed frequency (145.875 MHz) does not appear and
memorized frequency (145.650 MHz) appears instead.
