Before starting, connect your key line to the front and/or
rear panel [
KEY
] jack, and be sure the [
KEYER
] switch
on the left side of the front panel is turned off for now.
1. Press the [
CW
] mode switch to engage CW operation.
The operating mode is selected using the Mode
switches to the left of the [
MAIN Tuning Dial
]
knob, and the VFO (A or B) to which the selection
is applied is selected by pressing the [
A
] or [
B
]
switch above the Mode keys. Please be sure you
are engaging CW on the right VFO.
The LED associated with your VFO and CW Mode
selection will light up.
If you press the [
CW
] key once more, after ini-
tially selecting CW, you wll engage the “CW Re-
verse” mode (see page 113), whereby the “oppo-
site” sideband injection is used, compared to the
“normal” sideband. The CW LED will blink for
three seconds if you select CW Reverse.
2. Rotate the [
MAIN Tuning Dial
] knob to select the
desired operating frequency.
3. Press the [ BK-IN/SPOT
] key momentarily to engage
automatic activation of the transmitter when you close
the CW key. The LED imbedded in the [
BK-IN/
SPOT
] switch will light up.

:
When you close your CW key, the transmitter will
automatically be activated, and the CW carrier
will be transmitted. When you release the key,
transmission will cease after a brief delay; the de-
lay time is user-programmable, per the discussion
on page 114.
As shipped from the factory, the
FT
DX
9000MP
TX/RX system for CW is configured for “Semi-
break-in” operation. However, using Menu item
“
MODE-CW 055 CW BK-IN ”, you may change
this setup for full break-in (QSK) operation,
whereby the switching is quick enough to hear in-
coming signals in the spaces between the dots and
dashes of your transmission. This may prove very
useful during contest and traffic-handling opera-
tions.
4. Operation using your CW key may now proceed.

You can monitor your sending by pressing the
[
MONI
] key, and adjust the [
MONI
] control
for a comfortable listening level on the CW
sidetone.
If you set the [
VOX
] and [
BK-IN/SPOT
] key
to Off, you may practice your sending without
having the signal go out over the air (sidetone
only).
