] jack.
1. Press the [ CW
] mode switch to engage CW operation.
If you press the [ CW
] key once more, after initially
selecting CW, you wll engage the “CW Reverse” mode
(see page 113), whereby the “opposite” sideband in-
jection is used, compared to the “normal” sideband.
The CW LED will blink for three seconds if you se-
lect CW Reverse.
2. Rotate the [ MAIN Tuning Dial
] knob to select the
desired operating frequency.

The LED imbedded in the switch will light up, confirm-
ing that the built-in Electronic Keyer is now active.
4. Rotate the [ SPEED

ing speed. Clockwise rotation of the [ SPEED
] con-
trol will increase the keying speed.
When you press either the “Dot” or “Dash” side
of your paddle, the transmitter will automatically
be activated.

When you utilize your keyer paddle, the transmitter
will automatically be activated, and the CW charac-
ters (or a strong of dots and dashes) will be transmit-
ted. When you re-
l e a s e t h e k e y e r
paddle contacts,
transmission will
cease after a brief
delay; the delay time
is user-program-
mable, per the dis-
cussion on page 114.

If you reduce power using the [ RF PWR
] control,
the ALC meter reading will increase; this is normal
and does not indicate any problem whatsoever (be-
cause increased ALC voltage is being used to lower
the power).
Full Break-in (QSK) Operation
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.
1. Press the [
MNU
] key to open the Menu.
2. Rotate the [ MAIN Tuning Dial
] knob to select
Menu item “ MODE-CW 055 CW BK-IN ”.
3. Rotate the [ CLAR/VFO-B
] knob to set this
Menu item to “FULL.”
4. Press and hold in the [ MNU
] key for two sec-
onds to save the new setting and exit.

In the CW mode, press and hold the [ CONT
] switch
for 2 seconds to activate the APF (Audio Peak Fil-
ter) which provides a very narrow audio bandwidth;
the LED inside the [

ber for four seconds every one second. The APF
circuit is an automatic circuit, and there is no ad-
justment knob for the APF.
