morse
a program to read and transmit morse code.
Reading morse is done through the fire button on
joystick port 2 which can be wired up to your keyer or to an interface
to your rig.
The default mode is to transmit in morse code, lines typed on the
keyboard. However, if the line begins with a # character then that
line is a command line and is interpreted differently.
The letter immediately after the # defines the command, and the
command may be followed by a number or a file name as specified
in the list below. Morse can also have a filename as argument when
it is started up, in which case input comes from that file instead
of the keyboard. If the file can't be opened then morse prints out
some documentation. Here are the commands.
The #a and #v parameters are checked for reasonable values otherwise
they could crash the system. If an illegal value is given then #v
will be set to 0, and #a will be 63.
#a n Set the audio volume to n.
#d n Set the duration to n. This specifies the transmitted speed
of morse characters (which is independent from the spacing
between the letters). The default value of 30 gives a letter
speed of about 26 wpm and increasing or decreasing this value
will change the transmission speed proportionately. (See also
the #w command)
#w n Set the word parameter to n. This specifies the spacing
between characters and defaults to 60. It should always be
set to NO LESS THAN twice the value of #d but can be increased
as large as necessary so that, for example, you can transmit
30 wpm characters that are spaced at a speed of 10 wpm.
#t n Set the tone of the transmitted sound. The default value of
700 generates a tone of approx 800Hz which zero beats with
my FT-101ZD sidetone.
#v n Specifies which channel the sound comes out. Defaults to
channel zero and can be 0-3.
#l n This value is used for receiving morse code and specifies
the dividing line between a dot and a dash. The default value
of 6000 gives a speed of about 20 wpm.
#u n This value specifies the length of time after which a key-up
is interpreted as a word-space. The default value of 18000
gives a speed of about 20wpm.
#e exit from the program (and close the file if it is open ...
see the f command).
#r Enter receive mode.
Receive mode is terminated when the program receives a key
down that is at least three word space elements long.
#g n Generate n lines of random text and transmit it as morse code.
The program generates random 'words' of varying lengths
with punctuation added (i.e. period, comma, and question mark)
with occasional strings of numbers which may contain
the / symbol. This mode can also be used to generate the
random text into a file by starting up the program with
output redirected.
#G n As for g except that the code is random 5 letter groups which
can contain alphanumerics and the characters , . ? and /
with equal probability.
#o Toggle the sound on/off. This is useful with the g and G
commands as morse can be executed as 'morse >file' so that
output goes to the file .... then toggle the sound off with
the #o command and then use the g or G commands which will
then generate random strings into the file without also
generating the sounds, which speeds things up for you.
#f <file> Redirect input to come from the named file instead of
the keyboard .... thus the file can contain any of the #
commands (except #f) plus a specific text.
#s Print the current settings of all settable parameters -
thus typing #s first thing prints the default values for
all parameters.
