OPERATION

FREQUENCY NAVIGATION

3) SCANNING

From the VFO mode, press and hold in the key for

one second, and while still holding in the key, rotate the DIAL knob to select the bandwidth for the VFO scan-

ner. Release the key to begin scanning toward a higher frequency. The scanner will stop when it receives a signal strong enough to break through the Squelch threshold. The VX-8Rwill then hold on that frequency according to the setting of the “RESUME” mode (Menu Item 83: SCAN RESUME ).

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 knob one click in the counter-clockwise direction while the VX-8Ris scanning. The scanning direction will be reversed. To revert to scanning toward a higher frequency once more, rotate the DIAL knob one click clockwise.

Press the PTT switch briefly to cancel the scanning. See page 60 for more details regarding Scan Operation.

You may initiate upward or downward scanning by pressing and holding

either or key for one second, respectively. In this case, the scanner scans the bandwidth that was previously selected.

Dual Receive Notice

The VX-8Rmay receive very strong signals on the Image frequency, and/or the receiver sensitivity may be somewhat reduced by the combination of the “A-Band” and “B-Band” frequencies while Dual Receive operation is engaged.

If you experience interference that you suspect may be coming in via an “Image” path, you may calculate the possible frequencies using the formulas below. This information may be used in the design of effective countermeasures such as traps, etc.
