MORSE MANIA version 1.0
Morse Mania was written by Edward Plumer (KM6IQ).
This program is offered as Freeware and may
be distributed and used freely. However, the
author reserves all rights.
INTRODUCTION TO MORSE MANIA
This program was written as a practice program
for people already familiar with the International
Morse Code. It allows the user to practice copying
Morse code at various speeds and at different audio
pitches. Code copy is displayed in a 11-character
scrolling display.
Parameter selection dialog box:
keying: Selects the speed (wpm) at which each individual
character is keyed.
sending: Selects the sending speed (wpm) of code. This is
the overall speed that the code will be sent at.
extra space is used between characters if this is
slower than the keying speed. This allows the user
to implement "Farnsworth" spacing. Typical novice
tests are given as (s=5,k=12), for the general test
(s=13,k=18), and for the extra test (s=20,k=21).
pitch: Set the audio pitch of the code (this is
approximate since the nearest note on the chromatic
scale was used). Volume, by the way, is set on
the "Control Panel" as usual.
pure tone: This option make the keyed note a pure,
sinusoidal tone as is typically heard on the
air. Leaving the option off gives a raspier
one, similar to what I have usually heard at
VEC tests.
delayed display: Most code practice programs will display the
letter AFTER the letter is keyed. This option
is for consistency with such programs. The
default option, which I prefer, is to
synchronize the display of the letter and the
keying of the letter.
Character generation menu:
Play File: Play the contents any user generated text file.
File must have the type TEXT, so when using
a word processor to generate a file, make sure
to save as "Text Only". The characters recognized
by the program are A--Z in UPPER CASE, 0--9 and
the symbols / . , ? + = *
The symbols + = * represent the prosigns
_AR_, _BT_ and _SK_ respectively. All white-space
is treated as a blank.
Play Char: Random groupings of A-Z.
Play Number: Random groupings of 0-9.
Play Calls: Random, valid US callsigns with prefixes W,K,N.
Portable calls are also generated.
Play Abbrev: Randomly play standard CW abbreviations and Q-codes
from a vocabulary of about 80 words.
Play RST: Randomly generated reports of the form
"UR RST ### UR RST ### ..." As on the air, the
better reports are heard more often.

Some notes and disclaimers about Morse Mania:
I make no warranties either explicit or
implied about this program nor its effect on
your system (although I have had no problems).
Due to the differing speed of various types of Macs, the
timing of the keying may differ slightly on different machines
due to processing overhead between characters. The keying
speed should be correct, however, the sending speed may be off
by a percent or so. I have provided a couple of sample text
files (5WPM.text etc) which contain copies of the word PARIS.
Each file should take 1-min to play given the appropriate
sending speed regardless of keying speed.
In order to implement the fancy desktop icon, I have defined
my own ╥creator type╙ called ╘MRSE╒. Beware that This
creator-type is not yet officially sanctioned by Apple and may
conflict with the creator type of some other programs out there.
I welcome any suggestions for added features, comments
on the current implementation, and any bugs.

-----------------------------------
v 0.3B
* added support for random call signs, random RST, separate
random characters and numbers
* carriage returns are now played as "blanks"
v 0.4B fixes 8/92
* changed code to use Apple Sound Manager instead of
Sound Driver.
* Program now works on "Outbound Systems" Notebooks
(ver 1.3 of firmware required).
* volume fading encountered before on some machines has been
corrected
v 1.0 10/92
* changed parameter dialog box to use radio buttons instead
of editable text fields for speed and pitch.
* included optional "pure tone" and "delayed display"
* Compatible with System v7.1, no fancy v7 features at this time
