Embedded Commands:
While in the message recording mode you may use embedded commands for
special features. To use an embedded command simply store the multi-
character embedded command code within your message.
/D
Decrement-decrements the serial number. Serial number 0001 will
decrement to 9999, skipping 0000 since it is not used. This feature
allows a serial number to be sent twice in a message.
Example:
UR RST 559 559 SN /N /D SN /N
/G
#
Gap-inserts a gap of
#
standard intra-character spaces into the message,
where
#
is a digit in the range of 1 to 9 (0 can be used but not
practical). Invalid numeral code will automatically default to zero.
This command is used to exaggerate inter-character and word spacing.
/L
Loop-creates a message loop (message repeat). Note that any character
recorded after "/L" will not be sent.
Example:
BEACON AA5CS 5 W /L
/N
Number-inserts a contest serial number, in the range of 001 to 9999,
into the message. Jumpers JMP4 to JMP8 controls the way zeroes and
nines in the serial number are sent. Only three digits are sent for
numbers less than 1000--use leading zeros when appropriate. The
serial number is automatically post-incremented each time it is sent and
updated in the non-volatile memory. Serial number 9999 will wrap-
around to 0001, skipping 0000 since it is not used. The serial number
is set to the same one as before when power on. If a different serial
number is desired, it must be programmed during power up. To
initialize the serial number, press and hold the
Message
button while
turning the power on until the keyer plays "GO" (dah-dah-dit dah-dah-
dah) and the LED flashes. You must then enter
four
numbers in Morse
code for a valid serial number, most-significant digit first (invalid
numeral code will automatically convert to zero). All numbers must be
in the proper Morse code format. For example, the number "1" must
be "di-dah-dah-dah-dah" and the number "0" must be "dah-dah-dah-
dah-dah". When four numbers are entered, the keyer will
automatically send an end of message character "+" (di-dah-di-dah-dit).
The keyer then resumes with normal operation when the LED stops
flashing. The serial number can be set from 0000 to 9999 (0000 will
automatically convert to 0001).
Example:
YOU ARE CONTACT NR /N
