Convenient Features; Dual Receive - Yaesu FTDX9000MP Operation Manual

The FT 9000MP 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
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 frequencies
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 increase 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 ] switch in the previous step,
you may also press the [ BAND ] keys 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 Sub [ RX ]
key; the Green LED imbedded within the Sub [ RX ]
key 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 083 HEADPHONE MIX" (see
page 156).
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 ac-
tual 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 057 CW
FREQ DISPLAY", described on page 153.
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 accomplished using
the Main [ SQL ] control.
