Advice
H 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.
H The FT DX 9000D 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, mo-
mentary 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.
9. Press the appropriate MODE key
(# ) to select the desired operat-
ing mode.
Advice
H 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.
H 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 by the
PITCH control), even though the actual tone
that you hear is not changing. 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 050 CW FREQ DIS-
PLAY,” described on page 136.
H 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 sensitiv-
ity to weak signals. Excessive advancement of the
SQL control will degrade the ability of the re-
ceiver to detect weak signals. Adjustment of the
Sub (VFO-B) band Squelch is accomplished us-
ing the Sub SQL control (# ); see page 31.

Advice
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.
