EXTERNAL KEYBOARD
MK offers the possibility to generate FSK and CW signals from directly connected PS2 keyboard. For
playing back stored CW messages the numeric PS/2 keypad is sufficient.

modes using the "CAPS LOCK" key.
CW mode allows to play the characters, play/record messages from/to internal memories, set the WPM
speed, tune function and the side tone. It has two submodes for playing and recording. During recording
mode it is possible to record characters written on the keyboard or played on the paddle.
