If you press the [ CW ] key once more, after initially se-
lecting CW, you will engage the "CW Reverse" mode
(see page 97), whereby the "opposite" 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 de-
sired operating frequency.
3. Press the [ KEYER ] switch.
The LED imbedded in the switch will light up, confirm-
ing that the built-in Electronic Keyer is now active.
4. Rotate the [ SPEED ] control to set the desired send-
ing speed. Clockwise rotation of the [ SPEED ] con-
trol will increase the keying speed.

You may confirm the keying speed when turning the
[ SPEED ] knob. The Sub (VFO-B) band frequency
display shows the keying speed for 5 seconds.
When you press either the "Dot" or "Dash" side of
your paddle, the transmitter will automatically be
activated.
5. If you press the [ BK-IN/SPOT ] key momentarily,
"semi-break-in" operation (discussed previously) will
be engaged.
6. CW operation utilizing your paddle may now commence.

DVICE
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 release the keyer paddle contacts, trans-
mission will cease after a brief delay; the delay time is
user-programmable, per the discussion on page 98.

DVICE
If you reduce power using the [ RF PWR ] control,
the ALC meter reading will increase; this is nor-
mal and does not indicate any problem whatsoever
(because increased ALC voltage is being used to
lower the power).

Full Break-in ( QSK ) Operation
As shipped from the factory, the FT
test 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) opera-
tion, whereby the switching is quick enough to hear
incoming 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.
Audio Peak Filter
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 [ CONT ] switch will glow um-
ber for four seconds every one second. The APF
circuit is an automatic circuit, and there is no ad-
justment knob for the APF.
