r
about some of the really neat features. . .
Now that you've mastered the basics
of VX-SR operation, let's learn more
VFO Mode
The
VX-SR's
display may be configured so
that only VFO-
A is displayed, or (alternatively) it
may be set for display
(in smaller characters) ofthe Main (A
or B) and
Sub VFOs .
As a third option, The Main VFO
(only) may be displayed
in small characters .
If the display currently shows the operating
frequency in
large characters (see the illustration),
press and hold in
the
[1(TN)FRQ]
key for one second to change
the dis-
play to indication of both the
Main and Sub VFOs . Press
and hold in the [1(TN)FRQ]
key for one second
again
to
make the Sub VFO frequency
disappear.
If the display currently shows
the operating frequency in
small characters, (displaying
one or both VFO frequen-
cies), press and hold in the
[4(MG)DSP]
key for one sec-
ond to cause the display to
double the size of the Main
VFO frequency. The Sub VFO
frequency will disappear.
If you again press and hold in
the
[4(MG)DSP]
key for one second, the LCD will
revert to
small-character display of the operating
frequency ; one or both VFOs will
be shown, de-
pending on how the display was set up
per the preceding paragraph .
Memory Mode
SETTING THE FREQUENCY DISPLAY IMAGE
SIZE
When operating in the Memory mode
(see page 42), press-
ing the [4(MG)DSP]
key for one second causes the
LCD
to "toggle" between display
of the current memory's fre-
quency
only
(large characters) or the current
memory's
frequency on the top line
and
the memory channel num-
ber on the second line .

VFO SPLIT MODE
For working
on repeaters with odd splits, or communicating
with astronauts on orbiting
space vehicles,
it may be necessary to use non-standard splits between the
receive and
transmit frequency.
If the application is infrequent enough not to warrant the
dedication of
a memory
channel for this purpose, the "VFO Split" mode may be used . Here is
the proce-
dure :
Set the
VX-5R
for display of both the Main and Sub VFOs, per the
preceding section .
(2) Press the VFO key, as needed, to
select VFO-A . Set VFO-A for the receiving fre-
quency (for example, 437 .950 MHz) .
Now press the
[VFO(DW)SC]
key, and set VFO-B for the desired transmit frequency
(e .g . 435 .750 MHz) .
Press the
[VFO(DW)SC]
key once more to re-establish VFO-A as the "Main"
(re-
ceive) VFO .
Press the [F[W] key, then press the
[BAND(SET)AR]
key to enter the Set mode .
Rotate the
DIAL to select Menu #09
("VFO SPLIT") .
Press the
[BAND(SET)AR]
key to enable activation of the VFO Split feature .
Rotate the
DIAL
one click to change the setting of this Menu item to ON . Press the
PTT key once to exit to Split VFO operation . You will notice the "[+][-]"
indicator
on the display, which signifies Split operation .
You will now be operating in a Split mode . When you press the PTT
key to transmit,
you will observe that VFO-A and VFO-B will reverse
positions . If you need to modify
the VFO-B (transmit) frequency (for Doppler Shift
correction, etc .), just press the
[VFO(DW)SC]
key, then make the necessary change, then press
[VFO(DW)SC]
key
once more to restore VFO-A to the "receive VFO"
position .
When you have finished with Split operation, re-enter
the Set mode, and set Menu #09
to OFF.

Advanced Operation
A split frequency pair set up via the VFO Split feature cannot be
stored di-
rectly into memory. You can, however, store odd frequencypairs
using a dif-
ferent (slightly simpler) procedure. Seepage 42.
