Change the Frequency
Navigation using the 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−8900R
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 extremely useful for
making rapid frequency excursions over the wide tuning range of the
FT−8900R
.
Direct Keypad Frequency Entry using the MH-48A6J Microphone
The keypad of the
MH−48A6J
DTMF Microphone may be used for direct entry of the
Main
band operating frequency.
To enter a frequency from the
MH−48A6J
keypad, just press the numbered digits in the proper
sequence. There is no decimal point key on the
MH−48A6J
keypad, so if the frequency is
below 100 MHz (e.g. 29.480 MHz), any required leading zeroes must be entered.
Examples:
To enter
146.480 MHz
, press
0 → 2 → 9 → 4 → 8 → 0
To enter
433.000 MHz
, press
4 → 3 → 3 → 0 → 0 → 0
Scanning
From the
VFO
mode,press the
key momentarily to initiate scanning toward a higher
frequency. The
FT−8900R
will stop when it receives a signal strong enough to break through
the squelch threshold. The
FT−8900R
will then hold on that frequency according to the setting
of the
Resume
mode (
Menu #34
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
knob one click in the counter-clockwise direction
while the
FT−8900R
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
key again to cancel scanning.
