8.5 Special Morse Characters
The PK-900's Morse program contains special keystrokes which you can
use to make transmission easier, faster and more enjoyable. The most
frequently used Morse "prosigns" are coded into the keyboard with keys
that have no direct representation in standard Morse. These special
"reserved" keys are listed below:
Morse Keystroke Abbreviation Meaning
...-.- * or < SK End of QSO
.-... & AS Wait
.-.-. + AR End of message
-.--. ( KN Go only
-...- = BT Break or pause
-.-.- > or % KA Attention
...-. ! SN Understand
.-.- [ AA New line
---. \ o Umlaut O

8.6 Morse Code Practice
Use your computer with your PK-900 to develop and improve your
manual CW sending and receiving skills.
Set your PK-900 for Morse receive operation on Radio Port 1 and
operate the hand key attached to your radio transceiver. In most
installations your hand keying will be sent to the PK-900 and
displayed on your monitor if your radio has an audio "input monitor"
or "sidetone" output and you've turned on those monitor functions.
The frequency of the monitor sidetone must be nearly 750 Hz or the
PK-900 will not be able to copy it.
Send test words to familiarize yourself with the relationship between
your hand-keying and the Morse appearing on your screen.
Practice keying at various speeds; observe how the system decodes your
"fist". You may be a bit unhappy or surprised at the quality of your
keying but after a few sessions you'll notice an improvement.
