Logikey K-3 KEYER

FUNCTION COMMANDS
Commands to the keyer are entered in Morse code using your paddle. To alert the keyer that a function is
desired, momentarily press buttons 1 and 2 simultaneously. The keyer enables the monitor, disables output
keying, and acknowledges your request by sending "F".
After hearing the "F", simply paddle in the desired function character(s) explained below. When the function
is complete, the monitor is automatically restored to its previous state, output keying is enabled, and the
previous operating speed is restored.
Input command strings and the function performed are as follows:
A Auto-space - toggles the automatic character spacing feature on or off. The keyer confirms the new
state by sending "ON" or "OFF". When on, auto-spacing aids the operator in forming properly
spaced characters within a word. Character crowding is prevented by forcing at least 3 elements of
space whenever more than 1 space has been detected. This effect is very noticeable at low speeds
and can be felt by highspeed operators as well. Without auto-spacing, character spaces are deter-
mined by the operator.
B d Bank - Message banking is provided as an option to support multiple operators or preloaded mes-
sages for different contest exchanges. In the default mode, there are six messages of 255 charac-
ters each. As an option, the available memory can be configured as three distinct banks each having
6 messages of 85 characters. Bank 1 is activated by the "B1" command. Similarly, commands "B2"
and "B3" activate banks 2 and 3 respectively. Banking is disabled by the "13Ø" command, and the
currently active bank can be queried with the "?B" command when in the Function Mode.
D Decrement - decrements the serial number by one, effectively canceling the automatic increment ap-
plied when last played from a message. The decrement function accommodates resending the last
serial number, as might be needed when a repeat of a contest exchange is requested, or canceling
the exchange with a station that proved to be a "dupe."
E Edit - allows the operator to append onto or edit an existing message by entering the "E" command
in function mode, followed by the number of the desired message. The keyer will find and play the
last word in that message. Then paddle in more text, or use the error symbol (seven or more dots)
to erase existing words, just like the delete procedure when loading a message.
F dd Function speed - sets the speed used for function entry to dd WPM, where dd are two digits in the
range 06 to 30. This speed is employed for entering commands and loading messages. It is inde-
pendent of the operating speed and is unaffected by the analog speed control. Alternatively, the
function speed can be made to follow the operating speed by using dd = 00.
H Hand-key - The keyer enters hand-key mode. Keying output follows closures of the dot or dash pad-
dle levers, allowing hand-sent code. Normal iambic keyer operation is regained by any button clo-
sure.
K dd Keying Compensation - increases keying on-time and decreases keying off-time by dd milliseconds,
where dd are two digits in the range 00 to 25. Although similar to increasing weight, the adjustment
is independent of speed. This setting is used primarily to correct keying distortion by certain trans-
ceivers. Note that the adjustment is not heard on the monitor output, except when playing back the
message from the "Inquire" mode.
L Load mode - toggles the load mode between character and real-time. The keyer confirms the new
mode by sending "C" or "R" as appropriate.
M Monitor - toggles the audio monitor on or off. The keyer is usually operated with the monitor off in
favor of the rig's sidetone.
N dddd Number - initializes the contest serial number to dddd , where dddd are four digits in the range 0000
to 9999. Note that 4 digits must be entered, with leading zeros if needed. Also note that in transmis-
sion of a serial number that a 4
th
place leading zero is never sent.
