BEEP MESSAGES
A. Control Character
The Control Character
9910
must be entered before the actual beep characters when
building a beep message. Remember, any message that does not have a control character
will be interpreted as a CW message!
B. Format
Enter the Control Character
9910
. Then enter the various beep character codes described
in the Beep Character Set to create the desired message. You may end the beep message
with the
*
character, or you may enter another Control Character (99xx) and continue with
another message type.
C. Delay Character
A special pre-message delay character,
54
, can be programmed after the Control Character
9910
but before the beep characters. The
54
causes the Message handler to pause for 1
second before sending the CW message. Any additional
54
s found after the first one will
be ignored. If the beep message was preceded by any other message, the
54
will be
ignored.
D. Factory-Fixed-Frequency Beeps
Forty-eight (48) beeps have been defined in frequency but have variable duration. These
beeps are programmed with the character codes
00
through
47
and cover almost four
octaves from 262 Hz to 3951 Hz. It is best to avoid beeps below 300 Hz and above 3000
Hz, since most radio systems are designed for 300-3000 Hz response.
E. Owner-Fixed-Frequency Beeps
Six (6) beeps are definable in frequency by the owner, and have variable duration. They
default to factory-selected frequencies upon a cold start. The frequencies may be changed,
and the new frequencies will be retained upon a warm start. These beeps are programmed
with the character codes
48
through
53.
F. Custom Beeps
Custom Beeps are defined "on-the-fly" in both frequency and duration. An 8-digit character,
57xxxxyy
, defines the Custom Beep. The four digits following the
57
, shown as
xxxx
,
represent the frequency and are taken from the Tone Code Table. The next two digits,
shown as
yy
, represent the duration in tens of milliseconds.
Custom beeps allow you to create a unique message with any frequency and any duration
to 990mS. As an example, let's define a custom beep of 1275Hz for 70mS. The custom
beep code would be
57078407.
