Logikey K-3 KEYER
18
A similar command, "R", as in "Resume", allows more timing tolerance for hand sent entry. Try putting an
"/R" command in a message where you want to insert hand entry. When the message plays to that point, it
stops, and you may now enter any hand sent material you desire. The keyer will not finish the rest of the
message until you press the same memory button again, at which point the message will resume. Both mul-
tiple "/R" and multiple "/B" commands may be entered in a message.
Another embedded command is the "/S" command which lets the operator set the speed in a message. Try
entering this message, then play it back: "/SØ6_CQ_CQ_/S12_CQ_CQ_/S24_CQ_CQ_/S48_DE WY9IE_AR".
Note that for speeds under 10 WPM, you must use a leading zero, as in "Ø6." When the stored message is
complete, the keyer speed will revert back to the knob setting. If you wish to revert to the knob setting in
the course of a programmed message that already includes a speed command, use a command "/SØØ".
This causes the message following the command to play at the knob speed.
A pair of embedded speed controls will probably be very useful for many contestoriented and DXpedition op-
erators, the /SUdd and /SDdd commands. These commands increase and decrease the speed of the keyer
from its current setting. These commands will be especially useful in exchanges with "canned" responses,
like "59904" or "599KW".
Load this message: "/SU15_59904_73_/SD15", then set your keyer to perhaps 10 WPM and send through
the paddle: "DC7XJ DE WY9IE", then press the message button. When you return to the paddle, you will
find you are back at 10 WPM or whatever speed you started at. As you can see, this ability to speed up an
expected message can give you more QSO's per hour in a contest situation, and thus can be extremely val-
uable. When embedding such commands, remember, any time you use an "/SU" command you will almost
certainly want to also use the complimentary "/SD" to restore the keyer to the speed it started at. And don't
forget that the speeds must be given in the command in two digits. So an increase of 8 wpm would be
"/SUØ8".
Another embedded command can be useful for a number of functions - the "/Gd", or "Gap" command. Re-
member when we talked about sending "WY9IE" and trying to put extra space between the "I" and the "E".
In a simplistic character mode message, that is impossible; the only option being a whole word space. The
other simplistic option is storing a message in the "Real-Time" mode.
But with the "/Gd" command, (The "d" as in "digit") it is possible to set an exact "gap" between the "I" and
the "E". Here's how. A normal space between two characters is 3 "bits" long. (A bit being the length as a sin-
gle dot.) The "/Gd" embedded command adds as many bit spaces as you want (up to 9) to extend a normal
letter space. Remember, the minimum space is three bits long, and the Gd command adds to that basic
space. A /G1 embedded command lengthens a space between two letters only a small amount. A /G4 com-
mand will open up the space from a letter space to a word space. Try programming "WY9I_/G2_E" and see
how it sounds. Experiment with different values for /Gd. Once you understand it, you will almost surely use
it for one special situation or another.
It's time to leave the subject of embedded commands and examine serial number generation, primarily use-
ful for contest operation. The Logikey serial number controls are unmatched by any other keyer design avail-
able. First, you must decide what number format you want to use. Do you send zeros in contest serial num-
bers using five dashes, three dashes, or a single dash? Do you use leading zeros? What about nines? Do you
spell out a proper nine, with four dashes and a dot, or do you follow the now common format of using an
"N", as in "5NN"? The Logikey "Zd" function command lets you specify your choice. Examine the Z Option ta-
ble in the accompanying instruction manual, and choose your serial number format.
Let's suppose you decide on option #6, with both leading zeros and other zeros sent as a "T". Now, enter
the function mode of the keyer and respond to the "F" prompt with the command, "Z6". This will cause gen-
erated serial numbers to reflect that format.
Now that that has been set, you also have the option of presetting a serial number. If you do not do so, the
first serial number sent will be "TT1". If you do want to preset a number, say 1066, enter the function mode
again, and answer the "F" prompt with the command, "N 1Ø66". Note that you must use a five-dash zero,
as in "1Ø66" even though the keyer will send it as a "T" under the "Z6" function. Now, enter the inquiry
mode by pressing buttons 5 & 6, and respond to the "?" prompt with an "N". The keyer will send back
"1T66", CW shorthand for 1066. If you want to reset the serial number at a low number such as "23", you
must use leading five dash zeros to enter a four digit number "ØØ23".
