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
9000 utilizes a triple band-stack VFO
DX
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 selectin switch. Up to four
TX/RX antennas may eb connected, or one RX-only
antenna.
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.

9. Press the appropriate MODE key
(# , see page 26) to select the de-
sired operating 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 maxi-
mum sensitivity to weak signals. Excessive ad-
vancement of the SQL control will degrade the
ability of the receiver to detect weak signals. Ad-
justment of the Sub (VFO-B) band Squelch is ac-
complished using the Sub SQL control (#
