The
VX-5R
will initially be operating in the “VFO” mode, as just described. This is a
channelized system which allows free tuning throughout the currently-selected operating
band. You can confirm that you are in the VFO mode by looking in the upper-left-hand
corner of the display; if you see “
Va
” (which stands for “VFO-A”) and/or “
Vb
” (VFO-B)
along the left edge of the LCD, then you are in the VFO mode.
Three basic frequency navigation methods are available on the
VX-5R
:
1. Tuning Dial
Rotation of the
DIAL
allows tuning in the pre-programmed steps established for the cur-
rent operating band. Clockwise rotation of the
DIAL
causes the
VX-5R
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
, 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-5R
.
2. Direct Keypad Frequency Entry
The desired operating frequency may be entered directly from the keypad.
The operating mode will automatically be set once the new frequency is entered via the
keypad.
To enter a frequency from the keypad, just press the numbered digits on the keypad in the
proper sequence. There is no “decimal point” key on the
VX-5R
, so if the frequency is
below 100 MHz (e.g. 15.150 MHz), any required leading zeroes must be entered.
Examples:
To enter 146.520 MHz, press
To enter 15.255 MHz, press
To enter 1.250 MHz (1250 kHz), press
To enter 0.950 MHz (950 kHz), press
3. Scanning
From the VFO mode, press and hold in the
[VFO(DW)SC]
key for one second.
The
VX-5R
will begin scanning toward a higher frequency, and will stop when it receives
a signal strong enough to break through the Squelch threshold. The
VX-5R
will then hold
on that frequency according to the setting of the “RESUME” mode (Menu #12). See page
63 for details.
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
one click in the counter-clockwise direction while
the
VX-5R
is scanning. The scanning direction will be reversed. To revert to scanning
toward a higher frequency once more, rotate the
DIAL
one click clockwise.
