Frequency Navigation - Yaesu FT-252 Operating Manual

Operation

Frequency Navigation

The FT-252 will initially be operating in the "VFO" mode, a channelized system which
allows free tuning throughout the operating band.
Two basic frequency navigation methods are available on the FT-252 :
1 ) Tuning Dial
Rotation of the DIAL allows tuning in the pre-programmed steps established for the op-
erating band. Clockwise rotation of the DIAL causes the FT-252 to be tuned upward in
frequency, while counter-clockwise rotation will lower the operating frequency.
If you press the [ F/MW ] key momentarily, then rotate the DIAL , frequency steps of 1
MHz will be selected. This feature is extremely useful for moving rapidly over the wide
tuning range of the FT-252 .
2 ) Scanning
Press and hold in either the [ p ] or [ q ] key for one second to initiate upward or down-
ward scanning (Manual VFO Scan).
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 direc-
tion while the FT-252 is scanning. The scanning direction will be reversed. To revert to
scanning toward a higher frequency once more, rotate the DIAL one click clockwise.
The scanner will stop when it receives a signal strong enough to break through the
Squelch threshold. The FT-252 will then hold on that frequency according to the setting
of the "RESUME" mode (Set Mode Item 29: ). Press the PTT switch momen-
RESUME
tarily to cancel the scanning. This only stops the scan; it does not cause transmission to
occur. See page 29 for details regarding Scan Operation.
