CW

Once you have selected your desired transmit speed, either by the above
Ctrl-C
n
directive, the
CW
nn
command, or by locking to a received station with the
Ctrl-C L
command, you can enter the
transmit mode by using the
Ctrl-C T
directive. At this point, the transmitter turns on and charac-
ters you type from the keyboard are sent over the air at the specified speed. Some split screen
terminal programs do not send any data to the
KAM
until you press the return key. Therefore you
may have long periods of no data periods of no data actually being transmitted. This has the ad-
vantage, however, of allowing you to go back and correct any typing errors you may have made.
Many other split screen programs will send your keyboard input directly to the
KAM
and thus, you
lose the ability to backspace and correct errors you have made. Still other programs will allow you
to change whether the keyboard input is sent immediately or delayed until you press the return or
enter key.
A very useful command for non-packet mode operation with the
KAM
is the XMITECHO command.
When this command is on, the characters you have typed on the keyboard will be echoed to the
terminal AS THEY ARE TRANSMITTED. This will allow you to determine if your terminal program is
sending your keystrokes immediately to the
KAM
or if it waits until you press the return key. In
most cases when operating non-packet modes, you will want to turn ECHO OFF in the
KAM
since
split screen programs will display typed characters in the transmit window.
Often in CW operation, you may want to send special PROSIGNS. Several common combinations
are available as single keystrokes from the keyboard and are listed below for your reference. For
instance, if I wish to transmit the BT symbol, I would simply type an
=
on the keyboard and the
KAM
will send the
BT
for me.

In addition to these pre-defined combination, the
KAM
has several user-definable characters which
may be programmed to be sent with a single keystroke. Also, the same combination that's sent,
can be displayed with a user defined one- or two-character sequence when your
KAM
receives that
code combination.
