Scanning - Yaesu VX-8GR Operating Manual

3 S
From the VFO mode, press and hold in the
holding in the
the bandwidth for the VFO scanner. Release the
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-8GR will then hold
on that frequency according to the setting of the "RESUME"
mode (Menu Item 77: 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-8GR is scanning. The scanning direction will be reversed. To revert to
scanning toward a higher frequency once more, rotate the DIAL knob one click clock-
wise.
Press the PTT switch briefly to cancel the scanning. See page 54 for more details regard-
ing Scan Operation.
The VX-8GR may 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.
