Depending on the setting of the [ A/B ] switch, the
function of the [ CLAR/VFO-B ] knob will
change. Please see page 34 for more details.
The FT 9000D utilizes a triple band-stack
DX
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.

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.

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 off-
set between the "zero beat" frequency and the
audible 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
appear when changing modes from (for example)
USB to CW, use the Menu item "MODE-CW
058 CW FREQ DISPLAY," described on page
151.
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 ]
control will degrade the ability of the receiver to
detect weak signals. Adjustment of the Sub band
(VFO-B) Squelch is accomplished using the Sub
[ SQL ] control; see page 31.
