The FT-2000D is capable of simultaneous reception on the same amateur band, using the Main (VFO-A) and Sub (VFO-
B) receivers, in what is 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 band (VFO-A), engage
the Sub (VFO-B) receiver by pressing the Sub [ RX ]
button, located to the upper left of the [ SUB VFO-B ]
knob. You will now be receiving on the two frequen-
cies shown on the frequency display.
2. Adjusting the volume:
To adjust the Main (VFO-A) audio level, rotate the
Main [ AF GAIN ] knob. To adjust the Sub (VFO-B)
audio level, rotate the Sub [ AF GAIN ] knob. In both
cases, clockwise rotation of the knob will increase the
volume level.
3. Press the [ B ] button. Within five seconds of pressing
the [ B ] button, while the orange LED is blinking, you
may now change the operating mode for the Sub (VFO-
B) band by pressing the appropriate Mode selection
button.
4. Having pressed the [ B ] button in the previous step,
you may also press the [ BAND ] buttons to select the
operating band on which you want to set up the Sub
(VFO-B) receiver.
5. Rotate the Main Tuning Dial knob to adjust the Main
(VFO-A) frequency, and rotate the [ SUB VFO-B ]
knob to adjust the Sub (VFO-B) frequency.
6. To cancel Dual Receive operation, and receive just on
the Main (VFO-A) receiver, press the Sub [ RX ] but-
ton; the imbedded green LED will go out, and
monoband operation on the Main (VFO-A) receiver
will resume.

:
Please remember that, while the [ B ] mode button is blink-
ing (for five seconds), 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 head-
phones (Stereo, Monaural, or Mixed) may be config-
ured using Menu item "089 rout HEADPHN" (see
page 124).
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 ] knob), 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 "061 A1A FRQDISP," described on page 122.
When operating on the FM mode on the Sub band
(VFO-B), rotate the Sub [ SQL ] knob clockwise just
to the point where the background noise is just silenced.
This is the point of maximum sensitivity to weak sig-
nals. Excessive advancement of the Sub [ SQL ] knob
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 ] knob.
The frequency ranges of the various fixed bandpass
filters are shown in the chart below. You may operate
on Dual Receive
RF BPF F
with both receivers
0.03000 MHz ~ 0.49999 MHz
0.50000 MHz ~ 1.69999 MHz
set within the same
1.70000 MHz ~ 2.49999 MHz
range, even if they
2.50000 MHz ~ 3.39999 MHz
are not on the same

Amateur band (for
6.90000 MHz ~ 9.89999 MHz
example, the 14 and
9.90000 MHz ~ 13.89999 MHz

13.90000 MHz ~ 20.89999 MHz
20.90000 MHz ~ 30.09999 MHz
24.9 MHz bands).
30.10000 MHz ~ 44.99999 MHz
Of course, a suitable
45.99999 MHz ~ 59.99999 MHz
multiband antenna is
required.
