Convenient Features; Dual Receive - Yaesu FTDX9000D - DATA MANAGEMENT Operation Manual

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.
MAIN(VFO-A) [ SQL ] knob
MAIN (VFO-B) [ SQL ] knob
1. While receiving on the Main band (VFO-A), engage
the Sub (VFO-B) receiver by pressing the [ SUB RX ]
key. You will now be receiving on the two frequen-
cies shown on the main frequency display.
2. Adjusting the volume:
To adjust the Main (VFO-A) audio level, rotate the
Main [ AF GAIN ] control. To adjust the Sub (VFO-
B) audio level, rotate the Sub [ AF GAIN ] control. In
both cases, clockwise rotation of the knob will in-
crease the volume level.
3. Press the [ B ] switch to enable the capability to change
the operating mode for the Sub band (VFO-B).
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
band (VFO-B), 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 ] knob to adjust the
Main (VFO-A) frequency, and rotate the [ CLAR/
VFO-B ] tuning dial to adjust the Sub (VFO-B) fre-
quency.
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.

Please remember that, so long as the [ B ] Mode
switch is illuminated, any mode or band changes
will still be applied to the Sub band (VFO-B),
whether or not Dual Receive is engaged.

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 operating in Dual Receive, the manner
in which the audio is fed to the left and right
sides of your headphones (Stereo, Monaural,
or Mixed) may be configured using Menu item
"RX AUDIO 084 HEADPHONE MIX" (see
page 154).
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 pro-
grammed 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 058
CW FREQ DISPLAY," described on page
151.
When operating on the FM mode on the Sub
band (VFO-B), rotate the Sub (VFO-B) [ 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 Main band (VFO-A) Squelch is accom-
plished using the Main [ SQL ] control.
