VX-7R OPERATING MANUAL16
FREQUENCY NAVIGATION
The VX-7R 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-7R:
1
)
Tuning Dial (Outer ring of dual control on Top Panel)
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-7R to be tuned toward
a higher frequency, while counter-clockwise rotation will lower the operating frequency.
If you press the 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-7R.

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-7R, 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

Scanning
From the VFO mode, press the key, then press the key. The VX-7R will begin scan-
ning toward a higher frequency, and will stop when it receives a signal strong enough to break
through the Squelch threshold. The VX-7R will then hold on that frequency according to the
setting of the “RESUME” mode (Menu Item: Scan Modes #3). See page 57 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-7R is scanning. The scanning direction will be reversed. To revert to scanning
toward a higher frequency once more, rotate the DIAL one click clockwise.
Press the PTT switch momentarily to cancel the scanning.
