Vertex Standard VX-177 manual Direct Keypad Frequency Entry, Scanning

OPERATION

FREQUENCY NAVIGATION

2) Direct Keypad Frequency Entry

The desired operating frequency may be entered directly from the keypad. The first “1” in the frequency does not need to be entered, as it is “assumed” by the microprocessor.

To enter a frequency directly, just key in the 10 MHz, 1 MHz, and the kHz digits.

Examples: To enter 436.560 MHz, press [3] ￿ [6] ￿ [5] ￿[6] ￿[0]

To enter 436.5625 MHz (12.5 kHz steps), [3] ￿ [6] ￿ [5] ￿[6] ￿[2]

3) Scanning

Press and hold in either the [￿(MHz)] or [￿(MHz)] key for one second to initiate upward or downward scanning, respectively (Manual VFO Scan).

For scanning within a limited sub-band range, from the VFO mode, press and hold in the [MR(SKIP)] key for one sec- ond to begin scanning toward a higher frequency within the previously-defined sub-band (Programmed VFO Scan). De- tails regarding sub-band setup may be found on page 37.

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-177 is scanning. The scanning direction will be re- versed. To revert to scanning toward a higher frequency once more, rotate the DIAL one click clockwise.

(MANUAL VFO SCAN)

(PROGRAMMED VFO SCAN)

The scanner will stop when it receives a signal strong enough to break through the Squelch threshold. The VX-177will then hold on that frequency according to the setting of the “RESUME” mode (Set Mode Item 32: RESUME). Press the PTT switch momentarily to cancel the scanning. This only stops the scan; it does not cause transmission to occur. See page 36 for details regarding Scan Operation.
