4. Once you have selected the desired band, you may initiate manual tuning (or scanning)

per the discussions on the next page.

Note 1

: The SW Band and Information Band reception is only possible on the “VFO-A”.

Note 2

: The VX-8R has an AM/FM Broadband radio. You can receive these bands

independently. See page ?? for details.

Note 3

: If desired, you may omit (skip) one or more bands from the band selection loop for

faster recall of your favorite operating bands. See page ?? for details.

Frequency Navigation

The VX-8R 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.

Three basic frequency navigation methods are available on the VX-8R:

1) Tuning Dial

Rotation of the DIAL knob allows tuning in the pre-programmed steps established for the

current operating band. Clockwise rotation of the DIAL knob causes the VX-8R 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-8R.

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-8R, 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 [V/M] key after the last non-zero

digit.
