Logikey K-3 KEYER

Speed changes within messages are also permitted, allowing parts of a message to be played at differing
speeds. Using relative changes as in "/SU15 QRZ DE WØSR/7O UP 5 /SD 15" plays the message faster but
then returns to the previous operating speed.
Messages may call other messages. Suppose message 4 contains "WA9CNS/KH7". Then the message "CQ
CQ CQ DE /4 /4 K" will, when played, yield "CQ CQ CQ DE WA9CNS/KH7 WA9CNS/KH7 K". Call nesting may
be as deep as desired. Thus, message #2 can call message #1 which calls message#4 which calls message
#3! In fact, continuous loops can be programmed. A loop will result if a message calls itself (directly or via
some other message).
Loops can be very useful. A CQ loop in message 1, using a pause, is a good example: "CQ DX CQ DX DE
WØWP WØWP K /P35 /1". The message will play continuously, with 3.5 seconds in between. When an
answering station is heard, simply tap either paddle to cancel the loop.
If you are fortunate enough to be able to "run 'em" in a contest, the break function and looping can be a
real advantage. Message 1 might contain: "QRZ TEST DE WØWP /B 599 IA BK /B /1 ". Here, activating mes-
sage 1 first causes "QRZ TEST DE WØWP" to be sent. The /B breaks the message and allows the responding
station's call sign to be copied. The call is then sent via the paddles. The message then automatically contin-
ues and sends "599 IA BK" followed by another break. The other station's report is then copied while the
keyer waits. A simple "TU" or "R" is then sent via the paddles to acknowledge the exchange. This completes
the break and causes an automatic loop back, restarting the whole sequence.
If no one responds to the QRZ, simply tap button 1 again to resend the QRZ (remembering that a /B is can-
celed by a button closure). If the responding station's exchange is missed during the second break, use
message 2 to ask for a repeat: "AGN? BK /B /1". After getting the repeat, acknowledge with "TU" or "R" as
before, and the QRZ loop is automatically resumed.
Setting up a beacon message can be useful for certain functions. Here would be a typical beacon message
attached to message #11: "/S2Ø TEST TEST DE KØHGB KØHGB /X /P5Ø E /1". This would send the mes-
sage "TEST" twice at a speed of 20 WPM, then sign the call, then send a 5 second carrier. The "E" at the
end will not actually go out over the air, but will serve to "break" the key-down condition, then the message
will loop back to the start, and recycle ad infinitum ad nauseum.
User Note: If the keyer gets excessive RF on the input or output leads it is possible that the keyer will hang
up, and operate improperly or not at all. In such cases, the user should first try removing power from the
keyer for 30 seconds, then reapply. If that does not cure the fault, do a complete reset by pressing buttons
1-3-4-6. If this fails to correct the keyer's problem there is some other fault.
