1) Tuning Dial
Rotating the
DIAL
knob allows tuning in the pre-programmed steps established for the current
operating band. Clockwise rotation of the
DIAL
knob causes the
FT-8800R
to be tuned
toward a higher frequency, while counter-clockwise rotation will lower the operating frequency.
On the “
Main
” band frequency, press the
DIAL
knob momentarily, then rotate the
DIAL
knob, to change the “
Main
” band frequency steps to 1 MHz per step. This feature is ex-
tremely useful for making rapid frequency excursions over the wide tuning range of the
FT-
8800R
.
2) Direct Keypad Frequency Entry (MH-48
A6J
Microphone)
The keypad of the
MH-48
A6J
DTMF Microphone may be used for direct entry of the “
Main
”
band operating frequency.
To enter a frequency from the
MH-48
A6J
keypad, just press the numbered digits in the
proper sequence. There is no “decimal point” key on the
MH-48
A6J
keypad.

3) Scanning
From the VFO mode, press and hold the [
SCN
] key for one second, then rotate the DIAL
knob to select the bandwith for the VFO scanner. Now, press the [
SCN
] key momentarily to
initiate scanning toward a higher frequency. The
FT-8800R
will stop when it receives a
signal strong enough to break through the squelch threshold. The
FT-8800R
will then hold
on that frequency according to the setting of the “resume” mode (Menu #34 (
SCAN
); see
page 66). See page 39 for details regarding the VFO Scan operation.
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
FT-8800R
is 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 [
SCN
] key again to cancel scanning.
