Convenient Features; Dual Receive - Yaesu FTDX9000D Operation Manual

C
ONVENIENT
The FT 9000D is capable of simultaneous reception, using the Main (VFO-A) and Sub (VFO-B) receivers, in what is
DX
called the Dual Receive mode. Especially useful for DX work, here is the operating procedure for Dual Receive operation.
1. While receiving on the Main (VFO-A) band, engage
the Sub (VFO-B) receiver by pressing the SUB RX
key (# ). You will now be receiving on the two fre-
quencies shown on the main frequency display.
2. Adjusting the volume:
To adjust the Main (VFO-A) audio level, rotate the
Main AF GAIN control (#
(VFO-B) audio level, rotate the Sub AF GAIN con-
trol (# ). In both cases, clockwise rotation of the
knob will increase the volume level.
3. Press the B switch (#
change the operating mode for the Sub (VFO-B) band.
4. Having pressed the B key in the previous step, you
may also press the BAND keys surrounding the TFT
to select the operating band on which you want to set
up the Sub (VFO-B) receiver.
5. After you have set up the band and mode for the Sub
(VFO-B) band, you should now select the proper an-
tenna, using the ANTENNA SELECT 1 ~ 4
switches, or, for receive-only capability, the RX (An-
tenna) switch.
6. Rotate the MAIN tuning dial (#
Main (VFO-A) frequency, and rotate the CLAR/
VFO-B tuning dial (#
B) frequency.
7. To cancel Dual Receive operation, and receive just
on the Main (VFO-A) receiver, press the RX switch
(# ); the Orange LED to the right of the CLAR/
VFO-B knob will go out, and monoband operation
on the Main (VFO-A) receiver will resume.
Note
Please remember that, so long as the B Mode switch
(# ) is illuminated, any mode or band changes will still
be applied to the Sub (VFO-B) band, whether or not Dual
Receive is engaged.
Quick Note
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.

Advice
H When operating in Dual Receive, the manner in which
the audio is fed to the left and right sides of your head-
phones (Stereo, Monaural, or Mixed) may be config-
ured using Menu item "RX AUDIO 076 HEAD-
PHONE MIX" (see page 139).
H When changing modes from SSB to CW, you will ob-
serve a frequency shift on the display. this shift repre-
sents 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 on the Sub (VFO-
B) band, rotate the Sub (VFO-B) SQL (Squelch)
control (# , see page 31) clockwise just to the point
where the background noise is just silenced. This is
the point of maximum sensitivity to weak signals. Ex-
cessive advancement of the SQL control will de-
grade the ability of the receiver to detect weak sig-
nals. Adjustment of the Main (VFO-A) band Squelch
is accomplished using the Main SQL control #
