- This software is intended to help people who want to improve their morse
- copying skills for amateur radio licenses. It is not a morse code tutorial,
- although a tutorial program could be constructed with the included
- routines. If you have no knowledge of morse code, I'd recommend the
- ARRL "Tune in the World with Ham Radio" kit. Once you know some of the
- letters, the quiz program in this set will help to memorize the entire
- required set. The files in this collection are:
-
- MORSE.C
- This is the C function that sends morse code at a given speed. It is
- fully GEM compatible. The methods for calculating the timing constants
- are illustrated in the comments. I've checked the output speed against
- the "PARIS" timing, and it appears to be about 5% slower than the nominal
- speed. The ASCII-->morse mapping used is similar to that used by the
- AEA morse senders.
-
- QUIZ.PRG + source files
- This one sends the entire required morse alphabet one character at a time
- for you to identify. The letters are sent in random order until you
- have correctly identified all of them. This approach will familiarize
- you with the sound of the letters at the target speed.
-
- SENDER.PRG + source files
- This program sends any text file in morse code. The character speed
- and the spacing speed are independent; you should set the character speed
- to a value slightly higher than your target speed and then find a spacing
- speed that you are comfortable with. Increase the spacing speed until
- it matches the character speed, and you are ready for the test. (I don't
- recommend slowly increasing the character speed, because the characters
- sound different as the speed changes, and that complicates the learning
- process.)
- There is also an option to automatically increase the spacing speed.
- If the increment value is greater than zero, it will be added to the
- spacing speed each time a blank line is read in the text file, until
- the spacing speed equals the character speed. This is useful in helping
- you to find your `natural' copying speed when you are starting out.
- Finally, you can choose either filtered or literal text. In filter
- mode, only characters in the required morse alphabet are sent; blank
- lines are sent as AR and EOF is signalled as SK. Use this mode to
- send arbitrary text files (eg, your mail, this documentation).
- In literal mode, the full ASCII mapping, including the [prosign]
- notation is accepted. This mode allows you to prepare simulated
- QSO `scripts' to play for code practice class or whatever.

- Feel free to distribute this ARC collection to anyone anywhere by
- any means. PLEASE keep the files together so the recipients can
- customize the programs as desired.
