The VX-3R/E will initially be operating in the “VFO” mode. This is a channelized system
which allows free tuning throughout the currently-selected operating band.
Two basic frequency navigation methods are available on the VX-3R/E :
1) T
UNING
D
IAL
Rotation of the DIAL knob allows tuning in the pre-programmed
steps established for the current operating band. Clockwise ro-
tation of the
DIAL knob causes the VX-3R/E to be tuned toward
a higher frequency, while counter-clockwise rotation will lower
the operating frequency.
If you press the [ F/W
] key momentarily, then rotate the
DIAL
knob, frequency steps of 1 MHz will be selected. This feature is extremely useful for
making rapid frequency excursions over the wide tuning range of the
VX-3R/E .
Note
: Do not forget to pull the DIAL knob to rotate the DIAL knob.
2) S
CANNING
From the VFO mode, press and hold in the [
BAND
] key for one
second, and
while still holding in the
[ BAND
]
key
, rotate the
DIAL knob to select the bandwidth for the VFO scanner. Re-
lease the [ BAND
] key to begin scanning toward a higher fre-
quency. The scanner will stop when it receives a signal strong
enough to break through the Squelch threshold. The
VX-3R/E
will then hold on that frequency according to the setting of the “RESUME” mode (Set
Mode Item 75:
SCN.RSM
). See page 54 for more details regarding Scan Operation.
If you wish to reverse the direction of the scan (i.e. toward a lower frequency, instead of a
higher frequency), just rotate the
DIAL knob one click in the counter-clockwise direction
while the VX-3R/E is scanning. The scanning direction will be reversed. To revert to scan-
ning toward a higher frequency once more, rotate the DIAL knob one click clockwise.
Press the PTT switch momentarily to cancel the scanning. This only stops the scan; it does
not cause transmission to occur.
Notice
The VX-3R/E may receive very strong signals on the Image frequency. If you expe-
rience interference that you suspect may be coming in via an “image” path, you may
calculate the possible frequencies using the formulas below. This information may
be used in the design of effective countermeasures such as traps, etc.
