Logikey K-3 KEYER
6
of the speed setting desired. For example, "Ø7" is 70 WPM, "77" is 770 WPM. Weighting (W), Com-
pensation (K) and Tone (T) settings are disabled during Ultraspeed transmission. Messages can be
created using both regular and ultra speeds. To exit Ultraspeed mode in a message, a "workaround"
is used. At the end of the desired ultraspeed text, send /SUØ1/SDØ1. This trick tells the keyer that
ultraspeed is ended and returns the keyer to the pot speed. Alternately, the message speed can be
set to a normal speed by use of the /S command, such as "/S2Ø" but this will send text following
the ultraspeed text at 20 WPM in this case, rather than the speed set by the panel speed control.
/X Close key - allows the keyer to send beacon messages that include extended key down periods.
Once started, the output keying will remain on until either the paddle is closed on either side or it is
timed out by a P
dd
embedded command. (see above) The P
dd
command controls the length of the
key closure. The P
dd
command should be followed by a letter "e" which will not be transmitted but
instead is used to "break" the key down mode. Regular text may then follow.
/1 Message 1 - message 1 is played in its entirety followed by resumption of the current message. To
create a continuous loop, end the message with the number of the message as an embedded com-
mand, such as "/1", where the "1" is the message being programmed or played. Also, other mes-
sages can be appended. For example, message #2's contents can be appended to the end of mes-
sage #1 by ending message #1 with a "/2" embedded command. And a loop could then be created
by ending message #2 with a "/1" embedded command.
MULTIPLE-BUTTON FUNCTIONS
Single-button closures are reserved for activating messages. As already discussed, the 1-2 combination
alerts the keyer for paddle-entry functions. Certain functions are duplicated, wholly or in part, by other but-
ton combinations:
3-4 Decrement - the keyer acknowledges with "D" and then decrements the serial number.
5-6 Inquiry - the keyer acknowledges with "?" and then waits for paddle entry of the desired option.
2-3 Hand-key - the keyer acknowledges with "H", then enters hand-key mode until another button clo-
sure occurs.
4-5 Tune - the keyer acknowledges with "X" and then keys the output continuously until a paddle clo-
sure occurs.
2-5 Reverse - the keyer acknowledges with "RV" and then reverses the paddles.
1-6 Speed Range Reset - the keyer speed range is reset to a range of 5 to 40 WPM, and the function-en-
try speed is defaulted to follow the knob. After pressing the buttons, the keyer acknowledges with
"OK". Turn the speed pot fully clockwise and send a few dots, then turn the pot fully counter-clock-
wise and send a few more dots. This recalibrates the pot position.
1-3-4-6 Complete Reset - All stored setting, memories etc. are erased and the keyer returns to original de-
fault settings.
Note: To kill a message already transmitting without sending a "dit" over the air, press any two buttons and
release.
LOADING CHARACTER MESSAGES
In character mode, each Morse character uses one byte of message memory. Precise 3-element interchar-
acter and 7-element interword spaces are employed when the message is played (unless modified using the
/G
d
function). To load a message, first confirm that character-mode loading is in effect by using the "L" In-
quiry function. Then press and hold the desired message button. After 2 seconds, a tone is emitted and the
button may be released. The keyer then sends "C" to confirm character mode and waits for input.
