Basic Operation:Receiving on Amateur Bands
FCC ID: K6620461X50 / IC: 511B-20461X50
Here is the typical start-up procedure for normal operation:
[POWER] Switch
[ANT] Switch
[VFO-A(RX)] Button
[AF GAIN] Knob
1. Turn on the external DC power supply.
2. Press and hold in the front-panel [POWER] switch
until the transceiver turns on. After
about five seconds (ten seconds if the
optional µ-Tuning Kit is connected), the
transceiver is ready for full operation.
3. The transceiver will start up on 7.000.00 MHz LSB,
and normal operation may begin.
Note:
To turn power off, press and hold in the front panel
[POWER] switch for two seconds.
4. Rotate the [AF GAIN] knob to set
a comfortable audio level on incoming signals or noise. Clockwise
rotation of the [ AF GAIN ] knob
increases the volume level.
Note:
When using headphones, start by rotating the [AF
GAIN] knob counter-clockwise, then bring the volume level up after you put the headphones on. This
will minimize the chance of damage to your hearing
caused by an unexpectedly high audio level.
5. Press the [(VFO-A)RX] Indicator/Switch to engage
the VFO-A; the imbedded
LED will glow green.
Advice:
If you press the [(VFOA ) RX ] Indicator/Switch
when the imbedded LED
is already glowing green,
the LED will now blink
“on” and “off”; this indicates that the VFO-A receiver is temporarily muted. Just press the [(VFO-A)
RX] Indicator/Switch once more to restore VFO-A
receiver operation.

[BAND] Button
[MODE] Button
6. Press the [BAND] button corresponding to the Amateur band on
which you wish to begin operation.
Advice:
 One-touch selection of each Amateur band between 1.8 and 50 MHz is provided.
The FT DX 3000 utilizes a triple band-stack VFO

selection technique, which permits you to store
up to three favorite frequencies and modes onto
each band’s VFO register. For example, you may
store one frequency each on 14 MHz CW, RTTY,
and USB, then recall these frequencies by successive, momentary presses of the [14] MHz band
button. Each Amateur band button may similarly
have up to three frequency/mode settings applied.
When
the [MHz] button (located to the left of the
		
[CLAR/VFO-B] knob), is pressed, the imbedded
LED will glow orange, and then rotation of the
[CLAR/VFO-B] knob will change the frequency
in 1 MHz steps.
7. Press the [ANT] button to select the appropriate antenna for the band in use.
Advice:
When you make an antenna selection,
that antenna is “remembered” by the
microprocessor in conjunction with the
VFO register in use.

8. Press the [MODE] button to select the desired operating mode.
Repeated presses this button, step
through the available selections.
Press and hold in the this button, will
toggle to the alternate mode.
For example, In the LSB or USB modes, press and
hold in the this button toggles between “LSB” and
“USB” mode.
Advice:
 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 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 via
the Menu item “055 MODE CW CW PITCH”),
even though the actual tone that you hear is not
changing.
 When operating on the FM mode, rotate the
[ SQL ] (Squelch) knob clockwise 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] knob
will degrade the ability of the receiver to detect
weak signals.
You may change the [RF/SQL] knob from the
RF GAIN function to the squelch function via
Menu item “036 GENERAL RF/SQL VR”.
9. Rotate the Main Tuning Dial knob to tune around the
band, and begin normal operation.
Advice:
 Clockwise rotation of the Main Tuning Dial knob
increases the operating frequency, one “step”
of the synthesizer at a time; similarly, counterclockwise rotation of the Main Tuning Dial knob
will decrease the frequency. Two settings, one
“normal” and one “fast”, are available on each
operating mode. Pressing the [ FAST ] button
engages the “Fast” tuning selection, see chart below.
 It is possible to set the frequency change over one
dial rotation, separately for the CW mode, using
the Menu items “084 TUN DIALSTP” and “085
TUN CW FINE”. See page 116.
 If you want to navigate rapidly, so as to effect
rapid frequency change, there are several techniques available:
 Direct keyboard entry of the frequency.
 Use the [CLAR/VFO-B] knob to tune in 1
MHz steps.
 Use the microphone’s [UP]/[DWN] scanning
keys, if your microphone is so equipped.
