Operating Manual
Basic Operation: Receiving on Amateur Bands
displayed by pressing the
BAND
button. Each
Amateur band key may similarly have up to three
frequency/mode settings applied. See page 39
for details.
6. Press the
MODE
button to display the available se-
lections.
Touch the corresponding key to select the desired
operating mode.
Advice:
By convention in the Amateur bands, LSB is
used on the 7 MHz and lower bands (with the
exception of 60 meters), while USB is utilized on
the 14 MHz and higher bands.
When changing modes from SSB to CW, you
will observe a frequency shift on the display.
This shift represents the BFO offset between the
“zero beat” frequency and the audible CW pitch
(tone) you can hear (the pitch is programmed via
the Menu item “
059 CW FREQ DISPLAY
”), even
though the actual tone that you hear is not chang-
ing.
To eliminate noise while the transceiver is not re-
ceiving any signal, press the
F
(M-LIST)
button,
then touch [
SQL
] on the LCD. “
SQL
” will ap-
pear on the LCD and the
MULTI
knob will func-
tion as the squelch knob. Rotate the
MULTI
knob
to adjust the squelch until the noise disappears.
1. Turn on the external DC power supply.
2. Press and hold in the front-panel
ON/OFF
switch
until the transceiver turns on.
3. The transceiver will start up on 7.000.00 MHz LSB,
(or the previously used operating frequency) and
normal operation may begin.
Note:
To turn power off, press and hold in the front panel
ON/OFF
switch for one second.
4. Rotate the
AF GAIN
knob to set a comfortable au-
dio level of the incoming signals or noise. Clockwise
rotation of the
AF GAIN
knob increases the volume
level.
Note:
When using headphones, start by rotating the
AF
GAIN
knob counter-clockwise, then bring the vol-
ume level up after you put the headphones on. This
will minimize the chance of damage to your hearing
caused by an unexpectedly high audio level.
5. Press the
BAND
button to display the list of Amateur
bands on the LCD, then touch a key corresponding
to the band on which you wish to begin operation.
Advice:

tween 1.8 and 50 MHz, 144 MHz, and 430 MHz
is provided.
Touch and hold [

] on the screen displayed by
pressing the
BAND
button to selection 5 MHz is
provided.
The
FT-991A
utilizes a triple band-stack VFO
selection technique, which permits storing up to
three favorite frequencies and modes onto each
VFO band register. For example, you may store
one frequency each on 14 MHz CW, RTTY, and
USB, then recall these frequencies by successive,
momentary touches of the [
