The
VX-3R/E
’s frequency synthesizer provides the option of utilizing channel steps of 5/
8.33/9/10/12.5/15/20/25/50/100 kHz per step (optional values differ depending on the band
selected). A number of steps may be important to your operating requirements. Automatic
(“AUTO”) step selection is based on the current operating frequency. The
VX-3R/E
is set
up at the factory in the “AUTO” configuration, which probably is satisfactory for most
operation. However, if you need to change the channel step increments, the procedure to
do so is very easy.
1.
Press and hold in the [
TXPO
] key for one second to enter the Set mode.
2.
Rotate the
DIAL
knob to select Set Mode Item 82:
STEP
.
Note
: Do not forget to pull the
DIAL
knob to rotate the
DIAL
knob.
3.
Press the [
TXPO
] key momentarily to enable adjustment of this
Item.
4.
Rotate the
DIAL
knob to select the new channel step size.
5.
When you have made your selection, press the
PTT
switch to
save the new setting and return to normal operation.
1) 9 kHz steps are available only when receiving on the BC band.
2) 8.33 kHz steps are available only when receiving on the Air band.
3) While operating on the BC band, you may only select channel steps of 9
kHz or 10 kHz; the other step selections are disabled.
4) 5 kHz steps are not available for use on 250 - 300 MHz, nor above 580 MHz.

The
VX-3R/E
provides for automatic mode changing when the
radio is tuned to different operating frequencies. However, should
an unusual receiving situation arise in which you need to change
to a different receiving mode, just press the [
MODE
] key. The
receiving modes available are:
AUTO
: Automatic mode sets the default values for the se-
lected frequency range.
FM
:
Narrow-bandwidth FM (used for voice communication)
AM
:
Amplitude Modulation
W-FM
: Wide-bandwidth FM (used for high-fidelity broadcasting)
Unless you have a compelling reason to do so, leave the Automatic Mode
Selection feature on, this will save time and trouble when changing bands. If
you make a mode change for a particular channel or station, you can always
store that one channel into memory, as the mode setting will be memorized along with
the frequency information.
