CW BREAK-IN
Break-in allows you to transmit CW without manually
switching between transmission and reception modes.
Two types of Break-ins are available: Semi Break-in
and Full Break-in.
Semi Break-in:
When the key contacts open, the transceiver
automatically waits for the duration of the time
period you selected. The transceiver then returns to
reception mode.
Full Break-in:
As soon as the key contacts open, the transceiver
returns to reception mode.

ELECTRONIC KEYER
This transceiver has a built-in electronic keyer that
can be used by connecting a keyer paddle to the
transceiver’s rear panel. Refer to “Keys for CW
(PADDLE and KEY)” {page 2} for details regarding
this connection. The built-in keyer supports lambic
(squeeze) operation.
ELECTRONIC KEYER MODE
There are 2 modes of operation when using an
electronic keyer for lambic keying operation. Mode A
completes the current key sequence you are sending
when you release the paddles. Mode B sends one
more key, opposite the current key you are sending,
upon releasing the paddles.

CHANGING KEYING SPEED
The keying speed of the electronic keyer is fully
adjustable. Selecting the appropriate speed is
important in order to send error-free CW that other
operators can copy solidly. Selecting a speed that is
beyond your keying ability will only result in mistakes.
You will obtain the best results by selecting a speed
that is close to the speed used by the other station.
