be sure you are engaging CW on the right VFO.
H The LED associated with your VFO and CW Mode
selection will light up.
H If you press the CW key once more, after ini-
tially selecting CW, you wll engage the "CW Re-
verse" mode (see page 104), 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.

desired operating frequency.
3. Press the BK-IN/SPOT key

IN/SPOT switch will light up.
H 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 105.
H As shipped from the factory, the FT
TX/RX system for CW is configured for "Semi-
break-in" operation. However, using Menu item

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.

Advice
H You can monitor your sending by pressing the
MONI key (#
(# ) for a comfortable listening level on the CW
sidetone.
H If you set the VOX (#
(# ) to Off, you may practice your sending without
having the signal go out over the air (sidetone only).
Terminology
H Semi-break-in
This is a pseudo- "VOX" mode used on CW, whereby
the closure of the CW key will engage the transmitter,
and release of the key will allow the receiver to reciver
after a short delay. No signals will be heard between
the spaces between dots and dashes (unless the send-
ing speed is extremely slow).
H Full break-in
Full break-in (Also known as "Full QSK") involves
very fast switching between transmit and receive, such
that incoming signals may be heard between the dots
and dashes as you send them. this allows you to hear a
station that suddenly starts transmitting on your fre-
quency, while you are in the midst of a transmission.
