1. Press the [ CW ] mode switch to engage CW operation.
If you press the [ CW ] key once more, after initially
selecting CW, you will engage the "CW Reverse"
mode (see page 111), whereby the "opposite" side-
band injection is used, compared to the "normal" side-
band. 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 [ KEYER ] switch.
The LED imbedded in the switch will light up, con-
firming 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.
The Sub band (VFO-B) frequency display will
show the keying speed for 3 seconds whenever
the [ SPEED ] knob is turned.
You may disable this feature (displaying the key-
ing speed) via Menu item "DISPLAY 022 LEVEL
INDICATOR." See page 146 for details.
When you press either the "Dot" or "Dash" side
of your paddle, the transmitter will automatically
be activated.

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.

When you utilize your keyer paddle, the transmit-
ter will automatically be activated, and the CW
characters (or a strong of dots and dashes) will be
transmitted. When you release the keyer paddle
contacts, transmission will cease after a brief de-
lay; the delay time is user-programmable, per the
discussion on page 112.

Full Break-in (QSK) Operation

RX system for CW is configured for "Semi-break-
in" operation. However, using Menu item "MODE-

switching is quick enough to hear incoming signals
in the spaces between the dots and dashes of your
transmission.

2. Rotate the [ Main Dial Tuning ] knob to select
Menu item "MODE-CW 055 CW BK-IN."

Menu item to "FULL."
4. Press and hold in the [ MNU ] key for two sec-
onds to save the new setting and exit.
