D Morse Code Settings
The COM/ID tone is sent according to the selected code (see Table D-1). The length of
the Morse code can be varied. For selected standard time scheme, the selected dot
length determines the setting of all other length parameters of the Morse code (dash
length, symbol space and letter space) . For selected user time scheme, all length
parameters of the code can be set independently. If no coding is entered, the COM/ID
tone is sent uncoded (key down).
The following values are default values:
●
A dot (.) has a tone duration of 100 ms
●
A dash (-) has a tone duration of 300ms
●
The time between two tones is 100ms
●
The time between two letters is 300ms
After each word, a word space is entered. The word repetition rate is 7 words per
minute. Since the word length can vary between 900 ms and 4500 ms, the word space
between the words varies accordingly.
Example:
ID code = MUC
The word length =
(300+100+300)+300+(100+100+100+100+300)+300+(300+100+100+100+300+100+1
00) = 3100 ms
