The VX-8DR will initially be operating in the “VFO” mode, as just described. This is a fre-
quency step system which allows free tuning throughout the currently-selected operating band.
Three basic frequency navigation methods are available on the VX-8DR :

Rotation of the
DIAL
knob allows tuning in the pre-pro-
grammed steps established for the current operating band.
Clockwise rotation of the
DIAL
knob causes the
VX-8DR
to be tuned toward a higher frequency, while counter-clock-
wise rotation will lower the operating frequency.
If you press the key briefly, 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-8DR
.

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-8DR , so if the frequency is
below 100 MHz (e.g. 15.150 MHz), any required leading zeroes must be entered. However,
there is a short-cut for frequencies ending in zero - press the
key after the last non-zero
digit.
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
To enter 430.000MHz, press
