CONVENIENT FEATURES

DUAL RECEIVE

The FT DX 9000D is capable of simultaneous reception, 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.

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 rep-

resents the BFO offset between the “zero beat” fre-

quency 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 DISPLAY,” 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 (# ) clockwise just to the point where the

background noise is just silenced. This is the point of

maximum sensitivity to weak signals. Excessive ad-

vancement of the SQL control will degrade the abil-

ity of the receiver to detect weak signals. Adjustment

of the Main (VFO-A) band Squelch is accomplished

using the Main SQL control (# ).

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 (# ). To adjust the Sub

(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 (# ) to enable the capability to

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 (# ) to adjust the

Main (VFO-A) frequency, and rotate the CLAR/

VFO-B tuning dial (# ) to adjust the Sub (VFO-

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.
