The
FT
DX
9000MP
utilizes a triple band-stack
VFO selection technique, that permits you to store
up to three favorite frequencies and modes onto
each band’s VFO register. For example, you may
store one frequency each on 14 MHz CW, RTTY,
and USB, then recall these VFOs by successive,
momentary presses of the [
14
] MHz band key.
Each Amateur band key may similarly have up to
three frequency/mode settings applied.
8. Press one of the [ ANTENNA SELECT ( 1~4
)]
switches to select the appropriate antenna for the band
in use; alternatively, if one is connected, you may also
press the [
RX
] antenna selection switch. Up to four
TX/RX antennas may be connected, or one RX-only
antenna.
When operating on the FM mode, rotate the
[
SQL
] (Squelch) control clockwise just to the
point where the background noise is just silenced.
This is the point of maximum sensitivity to weak
signals. Excessive advancement of the [
SQL
] con-
trol will degrade the ability of the receiver to de-
tect weak signals. Adjustment of the Sub band
(VFO-B) Squelch is accomplished using the Sub
[
SQL
] control.
10. Rotate the [ MAIN Tuning Dial
] knob to tune around
the band, and begin normal operation.

:
Clockwise rotation of the [ MAIN Tuning Dial
]
knob increases the operating frequency, one “step”
of the synthesizer at a time; similarly, counter-
clockwise rotation of the [
MAIN Tuning Dial
]
knob will decrease the frequency.
Two steps, one “normal” and one “fast,” are avail-
able on each operating mode. Pressing the [
FAST
]
key engages the “Fast” tuning selection.

It is possible to separate the frequency change over
one dial rotation, while operating solely on the
CW mode, using the Menu items “
TUNING 139
DIAL STEP ”, and “ TUNING 140 DIAL CW
FINE ”. See page 160.
If you want to navigate quickly, so as to effect
rapid frequency change, there are several tech-
niques available:
z Direct keyboard frequency entry of the fre-
quency (see page 61).
z
Use the [
CLAR/VFO-B
] knob to tune in 1
MHz steps (see page 61).
z Use the microphone’s Up/Down scanning keys,
if your microphone is so equipped.

Once you have made your antenna selection, that an-
tenna is “remembered” by the microprocessor in con-
junction with the VFO register (frequency and mode)
in use when you chose that particular antenna.
9. Press the appropriate [ MODE
] key
to select the desired operating mode.

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 au-
dible CW pitch (tone) you can hear (the pitch is
programmed by the [
PITCH
] control), even
though the actual tone that you hear is not chang-
ing. If you do not want this frequency shift to ap-
pear when changing modes from (for example)
USB to CW, use the Menu item “
MODE-CW
058 CW FREQ DISPLAY ”, described on page
153.
