15.7. MorseKeyer
Summary: The MorseKeyer component is used to create a 4-letter morse code
sequence.
Description: The MorseKeyer component is used to translate 4 letter words into
Morse Code. The component allows control over the wordrate, interval and the fre-
quency (pitch) of the generated tone. In addition to the usual letters and numbers
defined in Morse code, it also includes the characters ‘*’ and ‘-’ to represent indi-
vidual dot and dash combinations.
Control Inputs
Enable
Type Default Value
boolean True
Description: When True it enables the Morse Keyer. When False
the Morse Keyer is disabled.
Frequency
Type Default Value
float32 1.0
Description: Provides the frequency (pitch) of the Morse tone.
Units are in Hertz.
Gain
Type Default Value
float32 1.0
Description: Scales the strength of the generated tone.
Ident
Type Default Value
ident n/a
Description: The 4-letter word that connects into Morse code. Ident
is a special variable Type which is defined as 4 ASCII characters
concatenated together. A HostIn component must be used to drive
this parameter.
Control Inputs
Interval
Type Default Value
uint16 1
Description: The total cycle in seconds before the ident message
starts playing including the pause. i.e. The wordrate time plus the
pause after the ident message (wordrate - interval) before a new
cycle begins. Interval number must be larger than the wordrate.
ILSPause
Type Default Value
boolean False
Description: When False, MorseKeyer uses normal Morse code
inter-character timing which is a three (3) dot gap between all ident
characters. When True, MorseKeyer uses a standard morse code
inter-word timing between the first and second characters (i.e. a
seven (7) dot gap). Inter-character timing for subsequent ident char-
acters will use standard Morse code inter-character spacing (i.e. a
three (3) dot gap).
Wordrate
Type Default Value
uint8 1
Description: Determines the rate at which the word is keyed.
Audio Output
OutSignal
Type Default Value
audio/audio n/a
Description: Outputs the keyed word when the PTT control is
enabled.
